摘　　要：针对棱柱形压缩弹簧稳定性研究方面的不足,运用相当刚度理论,考虑剪力的影响,对于临界载荷,得到了小升角对称棱柱形压缩弹簧的横向失稳条件及不同条件对稳定性的影响,得出了圆柱形压缩弹簧是其特殊情况等结论.In order to study the stability of symmetrical prismatic pressing spring, the comparative rigidity theory is applied; for critical load, the transverse instability conditions for the symmetrical prismatic pressing spring with small rising angles have been obtained, considering the effect of sheering forces. The effect on stability of different conditions was discussed. This paper points out some results, for example, the cylinder spiral spring can be treated as a special case of that of the symmetrical prismatic spring.
