摘要
建立了套在光滑旋转金属杆上圆柱形弹簧模型.运用微元分析法,得到了弹簧形变量的微分方程,并求得了表达式.实验验证了弹簧总长度与旋转角速度的关系式.
The model of circular spring encircling a rotating smooth metal rod is established. The differential e- quation of displacement is derived by infinitesimal analysis method and the solution is given. The theoretical expres- sion of total length of spring in rotation frame is given, which is in good agreement with the experiment data.
