摘要:机构学中存在着大量的混沌现象,有时会严重影响机构的特定性能,混沌的控制或利用是机构混沌研究的重要课题。为找到控制混沌的有效方法,首先利用Largrange方法建立了机构数学模型,通过MATLAB进行数值仿真,动力响应特性分析表明该机构为混沌机构;然后应用变胞原理对此混沌机构进行变胞,通过MATLAB对变胞后的机构进行数值仿真,从动力响应特性可以看出,混沌现象消失,变胞后的机构为非混沌机构。研究结果表明,应用变胞原理控制机构的混沌是一种可行的方法。

Abstract:There is a large number of chaotic phenomena in mechanisms, which will affect the specified characteristics of mechanism seriously sometimes. The control or the use of chaos is an important issue of the research in chaotic mechanism. In order to find the effective method to control chaos, this paper used the Lagrange method to establish the mathematical model of mechanism, and got numerical simulation by using MATLAB. The dynamic response showed that the mechanism is chaotic mechanism. The paper turned chaotic mechanism by using the metamorphic principle,and got numerical simulation by using MATLAB. The chaotic phenomena disappeared by the dynamic response, which showed that the mechanism is non-chaotic mechanism. It means that it is a feasible method to control chaos of mechanism by using the metamorphic principle.
Key words:Largrange;metamorphic principle;mechanism;chaotic control
