间歇传动链系统的动力学分析
|
摘要
分析了影响传动链系统间歇运动的动力学因素,讨论了传动链系统的动力学建模方法,建立了传动链系统动力学方程,然后采用模态叠加法求解方程。为了验证建模的准确性,以模切机间歇传动链系统为例,建立了动态实验装置,对链条间歇运动的动态特性进行了测试和分析。实验结果表明,提出的建模方法精度较高,为深入研究间歇传动链系统特性提供了依据。
The dynamics factors affecting the intermittent motion of the transmission chain system are analyzed. The dynamics modeling method of the transmission chain system is discussed. The dynamics equation of the transmission chain system is established, and then the equation is solved by the modal superposition method. In order to verify the accuracy of modeling, taking the die-cutting machine intermittent transmission chain system as an example,a dynamics experimental device is established to test and analyze the dynamic characteristics of chain intermittent motion. The experimental results show that the modeling method has higher precision. It provides a basis for in-depth study of the characteristics of the intermittent transmission chain system.
