Similarly, for situation shown in 2B, the first extrusion head and first is generated the trend being located remotely from each other by pressure head first, Process is similar with the above process.
Other design details of embodiment one are as follows:
First connecting rope 3-1-2 is in the part of first pulley 3-1-1 and the first anchor 2-1-3 and one ontology 2- of component The extending direction of 1-2, the i.e. direction of vibration of building one are parallel, in first pulley 3-1-1 and the first cable fixing member 3- The part of 1-3 is then parallel with the axis direction of First piston bar 1-1-2;
Second connecting rope 3-2-2 is in the part of second pulley 3-2-1 and the second anchor 2-2-3 and two ontology 2- of component The extending direction of 2-2, the i.e. direction of vibration of building one are parallel, in second pulley 3-2-1 and the second cable fixing member 3- The part of 2-3 is then parallel with the axis direction of second piston bar 1-2-2;
It is as follows for the program analysis of above-mentioned the application:
For the ease of the transmitting of extruding force, as shown in figure 3, first by pressure head vertical-horizontal slope ratio x less than 1;
First point discussion, in the first extrusion head and first by pressure head from equilbrium position to the state being located remotely from each other, if initially Under state, the first extrusion head is contacted with first by both pressure heads, since x is less than 1, far from when, the first extrusion head and the One by pressure head during contact, will lead to the first connecting rope and be in certain tensional state;But then balance is returned to it During position, it will lead to first and squeezed bad situation by pressure head.
But the first extrusion head under original state is not contacted with first by both pressure heads, not necessarily condition, because For direction of the adjustable first connecting rope 3-1-2 in the part of first pulley 3-1-1 and the first anchor 2-1-3.
Component one ontology 2-1-2 and the first extrusion head 2-1-1 move right dL distance, consider the influence of pulley, and first By the climb of pressure head are as follows: dy=dL/cos θ;θ indicate original state under the first connecting rope 3-1-2 first pulley 3-1-1 with The angle of the part of first anchor 2-1-3 and the direction of vibration of one ontology of component;
The dL distance and the first extrusion head 2-1-1 moves right, can allow first climb dy1=dL by pressure head x
It needs to meet: dy≤dy1 and is just avoided that the situation of Fig. 4.
It is found that in the case of 1≤xcos θ, the problem of can avoid Fig. 4.
As the above analysis, at θ=0 °, 1≤x can just be met the requirements, however when 1≤x, and stress is difficult to realize, i.e., and the One extrusion head and first excessive by the pressure between pressure head, may result in first hit by pressure head it is curved.
Therefore at θ=0 °, first is not contacted by pressure head with the first extrusion head under original state, is in contrast preferable Design.
Second point discussion, in the first extrusion head and first by pressure head from equilbrium position to state close to each other, then again It when returning to equilbrium position, needs to guarantee, the first connecting rope 3-1-2 remains relaxed state, is otherwise returning to balance position When setting, damping action is necessarily had, the main body design of this and the application are runed counter to.
L distance has been moved to the left in the first extrusion head, and first by the downward distance of pressure head is Lx;θ=0 ° the case where Under, the relaxed length of the first connecting rope are as follows: L-Lx, that is, as long as x≤1, can meet: flat returning in the case where θ=0 ° When weighing apparatus position, the effect of damping action will not be generated.
Consider in elongated situation, the difference in height of the anchored end of the center of circle of first pulley and the first anchor is u, first Extrusion head has been moved to the left L distance, and the radius of first pulley is r, and θ indicates that the first connecting rope 3-1-2 is first under original state The angle of the part of pulley 3-1-1 and the first anchor 2-1-3 and the direction of vibration of one ontology of component, the expression of θ 1 are moved to the left L apart from when the first connecting rope 3-1-2 the part of first pulley 3-1-1 and the first anchor 2-1-3 and component one The angle of the direction of vibration of body;
Original state, the first extrusion head and first is by pressure head when being contacted with each other,
First by the downward distance of pressure head be Lx, the relaxed length of the first connecting rope are as follows:
[r θ+(u+rsin θ)/sin θ]-[r θ 1+ (u+rsin θ 1)/sin θ 1]-Lx(θ, 1 θ indicate radian)
Wherein, the method for solving of θ 1 are as follows:
Rsin θ 1+(u+rcos θ 1) cot 1=rsin of θ θ+(u+rcos θ) cot θ-L
It only needs to meet: [r θ+(u+rsin θ)/sin θ]-[r θ 1+ (u+rsin θ 1)/sin θ 1]-Lx >=0.
Above formula, it should which positive number is taken for arbitrary L(), it should all meet and just may be used.
