【摘要】：为研究RV减速器系统的弹性特性、齿轮间啮合刚度和阻尼对系统动态特性的影响,需要对系统进行建模和仿真分析.由于采用传统动力学建模存在部分物理过程难以用数学方法表达,状态方程繁琐难以求解等缺点,采用键合图理论建模的方法能够避免这些缺陷,实现系统规则化建模.建立了RV减速器的键合图模型,利用键合图专用软件20-Sim进行仿真分析.仿真结果表明:键合图模型是一种相当优越的数学模型,应用键合图理论对系统进行仿真能较好地反映系统的动态特性,为RV减速器的设计、改进提供一定的理论依据.
[Abstract]:The elastic characteristics of reducer system for the study of RV, influence of gear meshing stiffness and damping on the dynamic characteristics of the system, the need for modeling and Simulation Analysis on the system. Because the traditional modeling part of the physical process is difficult to be expressed by mathematical method, the state equation is difficult to be solved the disadvantages of methods using bond graph theory modeling to avoid these defects, realize the system rules of modeling. Established RV reducer bond graph model of software 20-Sim was used to simulate and analyze the key. The simulation results show that the bond graph model is a mathematical model of a superior, the application of bond graph theory to simulate the system can better reflect the dynamic the characteristics of the system, RV reducer design, provide a theoretical basis for improvement.
