|
摘要
针对机械系统动力学仿真分析软件ADAMS中的多接触求解困难问题,基于粘滞阻尼理论来研究多接触求解,以及接触参数的设置对结果的影响,通过理论与实践相结合,分析了在多接触问题求解过程中最大阻尼系数Cmax对系统的多接触仿真分析结果的影响,为多接触问题的研究提供了一些理论基础与实践经验,且对此问题的进一步研究具有一定的参考与借鉴作用。
According to the multi-contact solving difficult problems of the mechanical system dynamics simulation software ADAMS,this paper based on the viscous damping theory to study the solving contact and setting parameters affect the results.Researched on how the maximum damping coefficient cmax affects the results of the system contact simulation and analysis in contact-solving process.The paper provides some theoretical basis and practical experience for the study of multi-contact problems,and has a certain amount of guidance on the multi-contact solving problems.
