压力机曲轴动力学仿真研究

Study on simulation of press crankshaft dynamics

运用Ansys建立某型压力机曲轴的有限元模型,结合ADAMS建立了包括曲轴柔性体以及随曲轴转动的零件刚性体在内的压力机曲轴系统的多体系统动力学模型,得到了关键构件的运动及载荷变化曲线,为深入研究曲轴系统动态响应奠定了基础。研究分析结果为压力机的优化设计提供了理论依据。

In this paper, Ansys is used to establish a finite element model of the press crankshaft, and then com- bined with ADAMS to establish a multi-body system dynamics model of the press crankshaft system that includes crankshaft flexible body and rigid parts rotating with the crankshaft. By utilization of this model, the paper presents the movement and load change curves of press key components, laying a foundation for in-depth study of crankshaft dynamic response. Re- sults of the study provide a theoretical basis for press optimal design.
