机械系统动态性能的好坏将直接影响系统的安全性与可靠性 ,因此 ,在对机械系统进行动力学分析时 ,计及各部件 (或构件 )变形的影响就显得非常必要 .当系统中含有梁式结构的构件时 (如凸轮机构、连杆机构等 ) ,常应用有限段方法建立系统动力学模型并对其进行动力学分析 .依据Kane方程 ,建立了梁式柔性体动力学的有限段模型 ,并编制了该方法的应用程序 .算例表明 ,有限段方法是分析梁式结构机械系统动态性能的一种简单、有效的方法
Mechanical system dynamic performance will directly affect the safety and reliability of the system, therefore, in the mechanical system dynamics analysis, it is necessary to take into account the impact of the deformation of each component (or component) is very necessary when the system contains In the case of beam-type structure components (such as cam mechanism, link mechanism, etc.), the finite element method is often used to establish the system dynamics model and perform dynamic analysis. According to the Kane equation, the finite element method Model, and the application of this method is compiled.Examples show that the finite-section method is a simple and effective method to analyze the dynamic performance of a beam-type mechanical system
