| 摘 要： | 运用分形接触理论,分析得到了轮盘结合面切向刚度模型,通过轮盘表面材料性能参数、拉杆转子法向载荷、切向载荷及轮盘表面的分形参数来得到轮盘结合面的切向接触刚度,对其变化规律进行数值仿真,并通过试验进行验证.研究结果表明:在定性理论模型上,分形接触理论是正确的,但分形理论有其适用范围,适用于粗糙度较小、拉杆转子法向载荷较大的...

| Abstract: | Based on the theory of fractal contact,the tangential contact stiffness of the roulette joint surface is calculated by the performance parameters,the normal load,the tangential force and the fractal parameters of the roulette surface.The tangential contact stiffness of the roulette joint surface is calculated and its variation regular numerical simulation,and through the test to verify.The results show that in the qualitative theoretical model,the fractal contact theory is correct,but the fractal theory has its scope of application,suitable for the roughness is small,the normal load of the larger model.In the experimental aspects of a good complement to the contact fractal theory of the applicable environment. |
