GERMAN PATENT OFFICE

The subject of the main patent application S 36261 IX / 42 k is a device for determining the Centers of gravity of a floating body z. B. a ship in which in a plane parallel to the plane of oscillation passing through the center of gravity of the body, at least three in one Polygon to each other and at a sufficient distance from the probable position of the center of gravity axis arranged measuring points are available, their Accelerations or decelerations are measured for each oscillation, the accelerations or delays in the measuring points are a measure of their distance from the center of gravity. In the main patent application it is already pointed out that for the proper determination of the Centers of gravity axes of a floating body (ship) according to the specified procedure certain special aids are required. Their purpose is to amplify the required measuring currents or measuring voltages for very small rolling or pitching vibrations and also the correction of the Gravity compensation at different heel or trim angles.

Another source of error can occur in the fact that the axis of rotation of the vibrations in rough seas not always exactly with the center of gravity

609 527/447

S 39774IX / 42 k

coincides, the center of gravity axis rather only corresponds to the middle position of the oscillation axis.

According to the invention, this error is avoided,

by including all measured acceleration resp. Delay values of each measuring point with their absolute

■■ Values summed up over a certain period of time and instead of the instantaneous values of the accelerations or decelerations measured at the measuring points the ratio of their sum values to the determination of the distances of the measuring points from the Center of gravity axis used.

This method is based on the consideration that in a sufficiently long period of time the Deviations of the momentary position of the oscillation axis from the real position of the center of gravity axis have to compensate, so that a deviation in one direction after a certain time one or the sum of several deviations in opposite directions Direction must correspond.

ao Another advantage of this procedure is that one also corrects the gravity compensation of the for. Measurement required masses proportionately can easily make and finally that the summation of even very small instantaneous measured values sufficient if the period is long enough. , Supplies measuring currents or voltages.

On the left:

However, with this method the position of the center of gravity is not continuously displayed, but only after the mentioned measurement period. However, this is not a disadvantage because of the location of the center of gravity usually does not change as quickly during the journey as the ones in question Measurement times could result in greater inaccuracies.

In Fig. Ι a force diagram is shown for two mutually opposite measuring points on both sides of the ship. The masses used to measure the accelerations are marked with m, their weights with G, the acceleration forces with B and the forces exerted by the measuring springs with F. Let the roll angle be φ, its amplitude (p _max . Furthermore, a heel angle φ _{0 is} assumed. The following calculation does not take into account that if the actual gravity

The resulting error can, as shown in the main patent application, be eliminated by a suitable design of the display device (cf. main patent application, FIGS. 5 a and 5 b).

From Fig. 1 result. the following balance of power :

The previous considerations are already given in the main patent application. They prove that the corrected instantaneous measured values are proportionate to the distances of the corresponding measuring points from the center of gravity. However, these measured values cannot be used directly for the integration, since the corrected measured values have opposite signs during the second half-period - their sum would therefore result in zero. If the measured values f during the first half-period are denoted by f _u and / " ₂₁ or f ' _u and f' _iU during the second half-period by f ₁₂ and f _i% or f ' _n and /" 22, then the values must the second half-period received a negative sign for integration:

In Fig. 2 this is shown by the dashed curves. In the case of the subject matter of the invention, this will be achieved by reversing the direction of rotation of the integration devices.

The figure shows of those shown in Fig. 4 a of the main patent application, in the square arranged two pairs of measuring points only the left measuring point. of the horizontal and the upper measuring point of the vertical pair. A corresponding arrangement must be provided for the other two measuring points.

A further rotary transformer 57 with the rotor 571 controlled by an inclinometer (gyro) via the axis 573 and the two-phase wound stator 572 are _{taken from alternating voltages e 12} , which correspond to the sine of the respective angle of inclination φ and thus the expression G sin (φ ₀ + y _mK sin ω ty relatively equal. the rectified by the rectifier 58.

e ₁₂ = ^ ₁ M ₁₂ = - k [G sin << p _o '-f Ψ, ηαχ sin ω ty. (18)

The axes of the two integration motors 561 and 562 are coupled to one another via a differential gear 563 in such a way that the speed M _{1 of} the third axis 564 of the gear unit is equal to the difference in the speeds M ₁

Belt 51 and cam 52 of the alternating current-fed rotor 531 of a rotary transformer 53 are adjusted so that voltages arise in the stator 532 of the rotary transformer which are proportional to the spring travel of the measuring springs or the accelerations to be measured (decelerations). The alternating voltages are rectified via a rectifier 54 and fed via the switching contacts 551 and 552 of the relay 55 to the integration motor 561, whose speed M _{11 is} proportional to the stator voltage of the rotary transformer e _n and thus to the accelerations (decelerations) to be measured

In the same way one obtains for the (not gen (drawn) measuring arrangement assigned to measuring point 1 Measuring point 3 (see. Fig. 4 a of the main patent application).

The arrangement for the measuring points of the horizontally lying pair of measuring points is somewhat different necessary.

The acceleration pendulum 2 (Fig. 3) with the mass 20 and the measuring springs 25 and 25 'adjusted t2o also by means of band 61 and cam 62, the rotor 631 of the rotary transformer 63 in such a way that the voltages of the stator 632 the accelerations (decelerations) to be measured at measuring point 2 are proportional. They are via the rectifier 64 and the. Changeover contacts 651 and 652

of the relay 65 is fed to the integration motor 661, the speed M _{21 of} which is proportional to the rotary transformer voltage e ₂₁ or the acceleration values.

e ₂₁ = k, M ₂₁ = k [[G (1 - cos O _n + cp _max sin ω t}) + mr ₂ ω ² (p _max sin ω i \.

Alternating voltages corresponding to the cosine of the respective angle of inclination φ are taken from the second stator winding of the rotary transformer 57. Furthermore, an AC voltage of such magnitude is taken from a transformer 67 with a fixed transformation ratio that the difference e _{22 of} the voltages of the fixed and rotary transformers rectified via the rectifiers 681 and 682 together with the associated parallel resistors 683 and 684 expresses the expression

G (x— cos <9? ₀ + <p _max sin ω t}}

is proportional. This voltage e ₂₂ is fed to an integration motor 662 with the speed W ₂₂ via the changeover contacts 653 and 654 of the relay 65.

= A ₁ « ₂₂ = k [G (1 - cos

_ax sin o> i ». (22)

The axes of the integration motors 661 and 662 are coupled to one another via the differential gear 663, the third shaft 664 of which has a speed M ₂ = M ₂₁ -M ₂₂ .

M ₂ = M ₂₁ -U ₂₂ = K- mr _% ω ² <p _max sin ω t. (23)

For the (not shown) measuring point 4 is obtained with an appropriate measuring arrangement

M ₄ = M ₄₁ - M ₄₂ = K ■ mr ^ ω ² cp _max sin ω t. (24)

The relays 55 and 65, which have only been briefly mentioned so far, are treated in accordance with those discussed above Considerations switched from a contact device controlled by an inclinometer, the indicates the mean heel (trim) value. They are used for the second half of the period to give negative integration values the corresponding positive sign to the oscillation.

The number of revolutions of the third shaft of the differential gear during any period T. is then

Ή = J ⁿ i dt = K ■ W ₁ o) ² (p _max [sin ca t dt (25)

The ratio of the number of revolutions per one Measuring arrangement pair is so

Jm ₁ dt jn ₃ dt

(26)

However, the simple integration device described has certain disadvantages. She is sensitive to tension and assumes constancy of the alternating supply voltage for a simple measurement. This However, the disadvantage is only of minor importance for the overall measuring arrangement, since it is not the absolute value but only the ratio of two integration values is required for the measurement. Furthermore, the calibration curve should the integration motors on the whole range, starting from zero, are linear, which in reality is not the case. This is all the more important as in the case of the integration motors due to the above ' reversing circuit described even a reversal of the direction of rotation is required. Below integration devices are therefore proposed which do not have these disadvantages.

In Fig. 4 the transmitter for inductive generation of alternating voltages as a function of the acceleration (deceleration) values of the measuring point 1 is the same as in Fig. 3 and consists of the mass 10 with the measuring springs 15 and 15 ', the mechanical transmission with belt 51 and cam disk 52 and the rotary transformer 53. The voltages taken from the stator 532 of the rotary transformer are, however, fed to two voltage transformers 533 and 534, the secondary side of which _{supply an identical voltage ^ 1} , which is the same as the acceleration values.

By means of a transformer 535 with a fixed transmission ratio, an additional voltage e ₀ is now generated and rectified via the rectifier 541. The voltages e _n , which are likewise rectified via the rectifiers 542 and 543, are added once additively and once subtractively to this direct voltage e _0. To this end, serve the appropriately sized parallel resistors 544, 545 and 546. The voltages e _{x 0} f e and e ₀ - e _x are through resistors 547 and 548 and the changeover contacts 551 and 552 of the relay 55 each one provided with additional excitation winding integration engine 101 or 102 supplied. Since their counter electromotive force is small in relation to the applied voltage and its armature resistance is also small in relation to the total resistance of the circuit, the back EMF can be neglected. The motors also have brake disks 103 and 104 and brake magnets 105 and 106 excited by the total current of the two motors.

The relays 55 (Fig. 5) and 65 (Fig. 6) are used as in Fig. 3 to the during the second half period of To give vibration to negative integration values the positive sign. But this does not happen how in Fig. 3 by reversing the direction of rotation of the integration motors, but in each case by interchanging of the supply lines for a pair of motors each. It is thereby achieved that all engines always run in the same direction and further how to get out. from the above calculations it can be seen that even the rotation value zero is never reached; rather, the integration can always take place in a speed range happen in which the calibration curve runs in a straight line.

In Fig. 7 of the axes 83 and 84 are the

: ■. so arms 853 and 872 will have made a full revolution before 863 and 882 do.

When both contact arm pairs have started their way from the drawn zero position, 853 and 872 will have reached the zero position again, while 863 and 882 have only reached the position shown in dotted lines. The resistors 871 and 881 of the rotary resistors, which should have the resistance value w , are connected with their beginning A via a resistor 891 or 892 with the resistance value w and with their end E directly with the free ends of a cross-connected cross-coil pair of the double cross-coil system 89 connected, whose coil pairs are connected in star. The wiper 872 of the rotary resistor 87 is connected to the positive pole via the normally open contact 915 of the relay 91, the wiper 882 of the resistor 88 via the protective resistor 893 to the negative pole of a direct current source.

Now the grinder 882 has the dotted line. Position reached and the resistance value χ tapped at the rotary resistor 88, the moving coil of the system 89 would move according to the

The contact tracks of the contact devices 85 and 86 each consist of one over the entire circumference with the exception of the zero position reaching contact piece 851 or 861 and one zero contact piece 852 each or 862. Relay 93 is on contact piece 851, the other end of which is on the positive pole of the coil. Relay 94, whose other end of the coil is connected to the negative pole, is connected to 861. The relays 93 and 94 can also be switched on by the contacts 951 and 952 of the relay 95. The contact pieces 852 and 862 are connected to each other via relay 95. The 853 wiper is on the negative pole, the 863 wiper at the positive pole of the power source. Relay 90 and that provided by capacitor 92 with drop-out delay Relays 91 can, as shown, via the normally open contacts 901 of the relay 90 and 911 of the relay 91 and via the normally closed contacts 902 of relay 90, 932 of relay 93 and 942 of relay 94 switched will. Furthermore, the pair of motors 101, 102 is through the normally open contact 931 of relay 93 and the normally closed contact 912 of relay 91, the motor pair 301, 302 through the normally open contact 941 of relay 94 and the normally closed contact 914 of relay 91 and the motor pair 601, 602 through the normally open contacts 933 of relay 93, 943 of relay 94 and the normally closed contact 913 of Relay 91 switched on or off. The mode of action is now as follows:

If the sliders 853 and 863 are in the zero position, the relay 95 is switched on. In order to relays 93 and 94 are also switched on via 951 and 952, respectively. These in turn switch with their contacts 931, 941, 933 and 943 all motor pairs. So the integration device begins to work until one of the two pairs of sliders 853, 872 or 863, 882 reaches the zero position again has. During this time relay 95 has dropped out again, but relays 93 and 94 remain via the ' Arms 853 and 863 and the contact pieces 851 and 861 turned on. Relays 90 and 91 cannot either

527/447

S 39774IX / 42 k

be operated because the normally closed contacts 932 and 942 are open.

However, has z. B. the faster running pair of sliders 853, 872 reaches the zero position again, while the pair of sliders 863, 882 is about only in the position shown in dotted lines, the supply circuit for relay 93 is first interrupted. This also interrupts the supply circuits for the motor pairs 101, 102 and 601, 602, and the wiper pair 853, 872 remains in the zero position. By yourself again. Closing normally closed contact 932- the relay 91 is now switched on, which in turn switches on the relay 90 with the contact 911 .. By contact 914 of the relay 91, the motor pair 301,302 is also switched off and stops. The contact 915 finally closes the measuring circuit for the cheese system, and the measurement proceeds in the manner described above.
The relay 90 switched on by relay 91 interrupts the circuit for relay 91 again immediately through its contact 902. However, this drops out with a delay, so that there is enough time for the measurement process, which is interrupted again after relay 91 drops out. The relay 90, in turn, maintains itself through its contact 901.

After relay 91 drops out again, contact 914 is closed again. Hence it works Motor pair 301, 302 switched off for a short time now continue again until the pair of grinders 863, 882 die Has reached zero position. At this moment the relay 95 and thus the relays 93 and 94 are switched on, the relay 90 is again de-energized by 932 and the supply circuits for the integration motor pairs closed again. So the game starts all over again.

Since the system 89 is switched on only during the short measuring time, it must expediently during the During the period of powerlessness held by a locking device in its last position.

Furthermore, the run of the remaining integration motor pair after the measurement are accelerated by an artificial circuit so that the grinder of this pair can reach the zero position again as quickly as possible and start the measuring process again can.

Finally, it is also possible if the measuring currents generated by the rotary transformers are very high Small oscillation processes should not suffice for a measurement, these measuring currents in the main patent application proposed way to reinforce.
