Description
Technical field
This utility model is related to a kind of suspension rod and in particular to a kind of be applied to the suspension rod measuring weight and center of gravity.
Background technology
Determine that weight of object and the position of center of gravity have very important meaning in engineering, particularly having safety requirements
Object application on especially show its importance.For example gondola extension fly during, gondola center of gravity must be limited to one fairly small
Design requirement in the range of, especially the takeoff and landing of aircraft when, the accuracy of gondola center of gravity directly affects flying of aircraft
Row safety；In the development process of various airborne plant equipment, the weight of various plant equipment and the determination of center of gravity are that design subtracts
The requisite work of shake system.
Because the measuring principle of center of gravity is especially clear and definite, can be using different measurement sides for different measurands
Method；Measuring Object barycentric coodinates method has gravitation method, suspension method, moment balancing method, moment of mass conservation method etc. multiple at present；For
The larger object center of gravity measurement of weight, moment balancing method is now the most frequently used one kind, using principle of moment balance Measuring Object
The mode of weight and center of gravity has three kinds of modes at present：Weighing platform formula, suspension type, jack type；Which kind of mode is all logical
The force cell crossing, or many strong points at 3 points at 4 points perceives the size of force value, then by acquisition system to sensor senses force value
The collection of data signal, by the resolving to this signal for the computer software, just obtains the positional value of object center of gravity.
The method of testing of main flow has the shortcomings that test condition is complicated, test error is larger or testing cost is higher at present.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of structure simple, easy to use
It is applied to the suspension rod of measurement weight and center of gravity.
In order to realize above-mentioned target, this utility model adopts the following technical scheme that：
A kind of suspension rod being applied to measurement weight and center of gravity, including the body of rod, the central point at described body of rod top is provided with hangers,
The bottom at described body of rod two ends is respectively provided with the hook that having electronic claims.
Above-mentioned hangers is arranged on body of rod top by reinforcement.The intensity of strengthening hanging.
The above-mentioned body of rod is homogenizing rectangle.Reduce the error of measurement.
Above-mentioned hook mutual back to.Ensure the safety of hanging, reduce the sliding probability hooking of hanging.
It is provided with reinforcing plate between above-mentioned hook and post.The intensity of strengthening hanging.
Above-mentioned hook is passed through some strengthening nuts and is connected with the body of rod.The intensity of strengthening hanging.
Of the present utility model it is beneficial in that：What this utility model provided a kind of is applied to measurement weight and the hanging of center of gravity
Bar, by being arranged on the hook that the having electronic at post two ends claims, large-scale rod component is sling, by the electronic scale of actual measurement
Measured value, calculate weight and the center of gravity of component according to equalising torque.Structure of the present utility model is simple, user
Just, maintenance cost is low, measures the weight of rod component and the process simple and fast of center of gravity, has very strong practicality.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is made with specific introduction.
A kind of suspension rod being applied to measurement weight and center of gravity, including the homogenizing rectangle body of rod 3, the central point at the body of rod 3 top sets
There is hangers 1, the bottom at the described body of rod 3 two ends is respectively provided with the hook 6 of the opening extroversion that having electronic claims.
Hangers 1 is arranged on the body of rod 3 top by reinforcement 2, is provided with reinforcing plate 5, passes through between hook 6 and the body of rod 3 bottom
Some strengthening nuts 4 are connected with the body of rod 3.
Linking up with 6 centre-to-centre spacing is 762mm.
During measurement, it is connected with lifting appliance by hangers 1.
The hook 6 of two having electronic scales is caught on two hangers 8 of component 7 respectively it is ensured that stress is vertical, uniform force.
By lifting appliance, whole component 7 is sling, to vacant state.
Now two electronic hanging scales can show two measured values.
Finally, weight and the center of gravity of component 7 is calculated according to measured value.
Component 7 is rod component 7, and coordinate system center is hangers 1 center, the center of gravity equal 0 of Y-axis and Z-direction, and X-axis is structure
The horizontal axis direction of part 7.
If two measured values are equal, illustrate that the center of gravity of component 7 is located at hangers 1 center, X-direction barycentric coodinates are
0.
Deviation of gravity center hanger 8 center of component 7 if two measured values are unequal, is described, if X-direction center of gravity
Coordinate is X, and A is the electronic scale display numerical value on one end hook 6, and B is the electronic scale display numerical value on other end hook 6, passes through
Torque equilibrium equation can calculate the numerical value of X.
A*(762/2-X)=B*(762/2+X)；
X=(A-B)*381/（A+B）.
Of the present utility model ultimate principle, principal character and advantage have been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment in any form limit this utility model, all by the way of equivalent or equivalent transformation
The technical scheme being obtained, all falls within protection domain of the present utility model.
