Mechanical Robust Design Based on ADAMS/MATLAB Joint Simulation

为了提升机械系统的精确度,首先构建ADAMS/MATLAB联合仿真的流程,确定ADAMS/MATLAB软件的输入和输出,并根据铝型材挤压机的特征添加约束力等参数。其次,根据建立的ADAMS/MATLAB仿真流程,模拟铝型材挤压机,由MATLAB软件得出仿真结果。最后,根据仿真结果,调整铝型材挤压机末端运动规律的冲击度,使铝型材挤压机可以平稳运行,提升铝型材挤压机的可靠性和稳定性。从运动学跟踪精度和加速度两方面对ADAMS/MATLAB的仿真结果展开测试,得出ADAMS/MATLAB仿真方法的运动学跟踪精度和加速度比较符合实际,精度较高,可以达到95%,误差较低,一般在3%左右,可以较好地还原铝型材挤压机的制作环境及制作过程,节约工业成本,降低错误率,提升机器质量。

In order to improve the accuracy of the mechanical system,the process of ADAMS/MATLAB co-simulation is first constructed,the input and output of ADAMS/MATLAB software are determined,and parameters such as binding force are added according to the characteristics of the aluminum extrusion machine.Secondly,according to the established ADAMS/MATLAB simulation process,the simulation of the aluminum extrusion machine is completed,and the simulation results are obtained by MATLAB software.Finally,according to the simulation results,the impact degree of the end movement law of the aluminum extrusion machine is adjusted,so that the aluminum extrusion machine can run smoothly and improve the reliability and stability of the aluminum extrusion machine.The ADAMS/MATLAB simulation results are tested from two aspects of kinematic tracking accuracy and acceleration,and it is concluded that the kinematic tracking accuracy and acceleration of the ADAMS/MATLAB simulation method are in line with the reality,with high accuracy,up to 95%,and low error,generally around 3%.It can better reduce the production environment and production process of aluminum extrusion machine,save industrial costs,reduce error rate,and improve machine quality.
