摘要
在螺旋升降机领域经常遇到细长杆问题,尤其行程比较大且丝杆直径较小的场合。针对细长杆联合强度问题,提出一种通过等效改变约束条件来进行稳定性分析的方法,可以得出相应的临界载荷。建立理论模型,通过有限元分析,对所提出的方法进行了验证。
In the field of screw elevator, the problem of slender rod is often encountered, especially when the stroke is relatively large and the screw diameter is small. In order to solve the problem of joint strength of slender rod, a method for stability analysis by changing the constraint equivalently was proposed, and the corresponding critical load can be obtained.A theoretical model was established, and the proposed method was verified by finite element analysis.
