摘要
为解决高精度转台的位置控制精度问题,以二维精密高速转台为研究对象,使用Ad-ams软件建立转台动力学模型进行仿真分析,以固定角度驻留效果来评价模型精度,实现了动力学仿真与分析.为进一步提高模型驻留精度,采用Amesim软件和Adams软件开展了联合仿真,由Adams软件负责传动计算求解,Amesim软件进行位置控制.相较于仅使用动力学模型进行仿真,联合模型的仿真结果相对误差在60°和120°的驻留分别减小到0.13%和0.09%,从模型精度上保证了联合模型在二维精密高速转台设计或改造上的准确性.最后对传动座样机进行测试,记录样机真实驻留角度,验证了联合模型的准确性和精度.
Abstract
To solve the position control accuracy problem of high-precision rotary tables,a two-dimensional precision high-speed rotary table was studied using Adams software to establish a dynamic model for simula-tion analysis.The model accuracy was evaluated based on the fixed angle retention effect,achieving dynamic simulation and analysis.In order to further improve the model retention accuracy,joint simulation was carried out using both Amesim and Adams software,with Adams software responsible for transmission calculation and solving,and Amesim software for position control.Compared with using only the dynamic model for simulation,the relative errors of the joint model simulation results at the retention angles of 60° and 120° were reduced to 0.13%and 0.09%,respectively,ensuring the accuracy of the joint model in the design or modifi-cation of two-dimensional precision high-speed rotary tables from the perspective of model accuracy.Finally,the transmission seat prototype was tested,and the actual retention angle of the prototype was recorded to verify the accuracy and precision of the joint model.
