捕捉缓冲机构刚柔耦合多体动力学仿真研究

Rigid-Flexible Coupling Multi-body Dynamics Simulation of Capture Buffer Mechanism

大部分动力学仿真分析采用的都是刚性构件,在现实生活中把构件看成刚性系统来处理可以满足要求,但这忽略了构件变形的影响。为了得到更真实有效的数据,就必须把模型的部分构件看作柔性体来处理。为研究某捕捉缓冲机构的动力学性能,从理论层面介绍动力学的研究方法和刚柔耦合研究的整体思路,并利用ANSYS和ADAMS导出的.MNF文件和.LOD文件,从刚柔耦合多体动力学的角度对捕捉缓冲机构进行了综合实验分析和对比。通过刚柔耦合研究实现了动力学和结构学的联合仿真,得到了更精确的仿真数据,在获得动力学测量数据的基础上又获得了结构学数据,使仿真结果更为全面,同时也为对结果要求较高的多体动力学工程仿真问题提供了参考。

Most dynamic simulation analyses use rigid components.In real life,it can meet the requirements to treat components as rigid systems,but this ignores the influence of component deformation.In order to get more real and effective data,part of the model components must be treated as flexible bodies.In order to study the dynamic performance of a capture buffer mechanism,the research method of dynamics and the overall idea of rigid-flexible coupling research were introduced from theoretical level,and the comprehensive experimental analysis and comparison of the capture buffer mechanism from the perspective of rigid-flexible coupling multi-body dynamics were carried out by using.MNF file and.LOD file derived from ANSYS and ADAMS.By this coupled study,the combination of dynamics and structural simulation is realized,the more accurate simulation data are gotten,the structural data are obtained on the basis of the dynamic measurement data,making the simulation results more comprehensive.It also provide some reference for multi-body dynamics simulation problems with higher requirements.
