摘要
文章从多体动力学的理论入手,介绍了ADAMS的接触理论,应用ADAMS建立了滚珠丝杠副的仿真模型;利用对比实验针对滚珠丝杠副的滚珠滚道截型的形状进行了仿真实验,分析了滚道截面形状对滚珠丝杠副动力学性能的影响,提高了滚珠丝杠副运转的平稳性。
In this paper, from the theory of multi-body dynamics, this paper introduces the contact theory of ADAMS, and then dynamic simulation model is established by using the muity-body dynamics simulation software ADAMS. Using the contrast experiment,the models of shape sof raceway section of the ball screw mechanism are simulated, analyzes the influence of dynamic performance on cross section shape of the raceway of the ball screw mechanism, and improves running stability of the ball screw mechanism.
