摘要
采用有限方法建立3-PRS并联机构的刚-弹耦合的多体系统动力学模型,并求解了该模型。建立的模型与MSCPatran的计算结果相差无几,误差率不超过5%,这说明模型是正确的,而且完全满足精度要求,从而开辟了虚拟轴机床动力学研究新的思路。
In this paper, rigid-elastic coupling muhi-body system dynamic modeling of 3-PRS parallel mechanism is established and solved by finite element method. The established modeling calculations with the MSC Patran is almost the same, error rate is no more than 5%, this shows that the model is correct, and fully meet the required precision, thus opened up new ideas of dynamics study of the virtual axis machine tool.
