某汽油机曲柄连杆机构多体动力学仿真
|
摘要
以某汽油机曲柄连杆机构为例,利用ADAMS/View软件在不考虑摩擦阻力与负载阻力的情况下建立了多刚体动力学模型,并采用Hypermesh软件将连杆进行柔性化处理,进而得到该机构的柔性体动力学模型。通过对多刚体模型和柔性体模型的动力学仿真结果对比分析发现,柔性体动力学模型更加接近于实际情况,可以为后续曲柄连杆机构的优化提供依据。
Taking the crank and connecting rod mechanism of a gasoline engine as an example,a multi-rigid body dynamics model is established by using ADAMS/View software without considering friction resistance and load resistance. The Hypermesh software were used to make the connecting rod flexible,and establish the flexible multi-body dynamics model. By comparing the simulation results of the multi-rigid body model and the flexible multi-body model,it is found that the flexible body dynamics model is closer to the actual situation and can provide a basis for the optimization of the subsequent crankshaft mechanism.
