Generally, initiating terminal or end of a period end of the position of fatigue fracture in vortex lines occur for flexure spring.It is conventional to reduce
The method of flexure spring stress concentration is to increase the radius of closing circular arc, to expand closed outline, eliminates stress concentration.This side
The shortcomings that method is, although stress concentration at this can be reduced by expanding closing arc radius simply, because excision is excessive
Material, while can also reduce the axial rigidity and radial rigidity of the flexure spring, the design that it cannot be satisfied refrigeration machine is made to want
It asks.
In the dynamics Design of small-sized Cryo Refrigerator, in order to make complete machine reach resonance, the quality of subsystem is controlled
It is very crucial.Flexure spring also shows particularly important as the part in entire subsystem, the control of quality.It is logical
For often, because flexure spring excircle is fixed, it is only vortex arm section really to participate in part of reciprocating vibration, generally according to
Experience takes the 1/3 of flexure spring gross mass to be used as mover quality.When by change flexure spring thickness or flexure spring arm it is wide come
When adjusting flexure spring quality, the mover quality really changed is not the practical quality increasedd or decreased of flexure spring, and
And by changing thickness and arm is wide adjusts flexure spring quality, the rigidity and stress of flexure spring can certainly will be influenced again, this is just
No small difficulty is brought to design.
