In order to ensure slow continuity and stability of falling operation, at any time should keep the operation module of more group to participate in that exhaust operation, the operation module of less group participate in ventilation reset operation and operation rotation rhythm is even as far as possible, this can by the double wedge line 11 of adjacent operation module (the operation module of establishing two ends is also adjacent block) keep taking central axis 1 as axle center with angle misplace in turn and the dislocation angle sum of the double wedge line 11 of all adjacent operation modules is π (rad), and the maximum center of circle angle that the relative sliding in cylinder 101 experiences when 102 exhaust of appropriate design exhaust pition realizes, Fig. 4 is the Pareto diagram of the double wedge line 11 of each operation module (having ten group job modules), taking central axis 1 as axle center, pass through and be respectively the double wedge line 1101 of the first group job module, the double wedge line 1102 of the second group job module, the double wedge line 1103 of the 3rd group job module, the double wedge line 1104 of the 4th group job module, the double wedge line 1105 of the 5th group job module, the double wedge line 1106 of the 6th group job module, the double wedge line 1107 of the 7th group job module, the double wedge line 1108 of the 8th group job module, the double wedge line 1109 of the 9th group job module, the double wedge line 1110 of the tenth group job module, the double wedge line 11 of adjacent operation module keeps
the dislocation in turn of angle.
Operation module group number is no less than 8 groups; meet in the accuracy of manufacture of descending lifeline under the prerequisite of descending lifeline corresponding component normal operation, cylinder 101, the size of annular connecting rod 103 and connecting rod guide rail 1031 and angle design should make exhaust pition 102 get large value with the radian of cylinder 101 inwalls generation relative slidings in one takes turns exhaust as far as possible, but be less than π (rad), many group jobs module that so ensures to keep at any time trying one's best only has at most as far as possible less group job module in reset operation in exhaust operation, just start or when the intermittent conversion of operation module job state slow falling, the pressure of uprushing by the many group jobs module in exhaust operation with certain proportion shared, weaken thus the pulsed impact of the interior gas compression of cylinder 101 causing because of the pressure of uprushing on the generation of tumbler rotating speed, compared with only having 2 group job modules, more operation module group number can obviously weaken tacho-pulse formula fluctuating range and increase the frequency of tacho-pulse formula fluctuation, when operation module group number is more and all cylinders 101 cross section of inboard wall area summations when larger tumbler can be rendered as satisfied relative uniform rotation state.Finally provide following data analysis:
Suppose that descending lifeline has 10 group job modules, and whenever have 9 group job module exhaust 1 group job modules to reset for simplifying to get in calculating; Cylinder 101 cross section of inboard wall area summations equal 200 square centimeters, and the bearing capacity that descending lifeline delays while falling is that 100 kgfs and this bearing capacity put on the interior gas of cylinder 101 through conduction unchangeably by exhaust pition 102 sizes.
If falling the pressure of uprushing while just beginning slow causes the interior gas of first compressed cylinder 101 to be compressed into the m of cylinder 101 maximum volumes
*/ 9.Have
Solve m
*boundary, between 3 and 2, has 7 cylinders 101 compressed when stress equalization is described.The radius of turn of supposing exhaust pition 102 mid points is 13 centimetres, is to the maximum at the slow linear distance (distance declining with 2 busts) that falls piston mid point process while just starting to uprush pressure
centimetre.This bust distance can not damage human body, also can not cause huge impulse force and make it to damage descending lifeline.
The pressure jump that the intermittent job state conversion of operation module also can make each interior gas of cylinder 101 in exhaust operation be subject to, makes originally newly to add the cylinder 101 of the exhaust pressure of uprushing altogether in exhaust condition and 101 and 1,8 cylinders continuing exhaust
newton, total pressure-bearing is increased to 2800 newton by 2689 original newton.If the reason pressure of uprushing causes being reduced in the interior gas volume of each cylinder 101 of exhaust operation the e/9 of cylinder 101 maximum volumes thus, can solve e according to following formula:
Can solve e=0.1983, illustrating declines is no more than with the distance of 2 busts
centimetre, can ignore on the impact of uniform descent.
The technical scheme of the present embodiment is applicable to the descending lifeline of above-mentioned arbitrary embodiment.
