为对某型周转斜盘发动机的动力学特性进行优化,建立了其连杆力模型、反作用转矩模型、接触转矩模型及主轴转矩模型.在对各数学模型进行仿真分析的基础上,提出设置2°的周向原始位移以保证反作用转矩始终为正,更改直导槽约束机构为“∞”型导槽约束机构以降低接触转矩和主轴转矩的波动幅度、减小滚轮与导槽的接触力、保证发动机主轴良好的输出特性.仿真研究表明:采用“∞”型导槽约束机构,并设置2°的周向原始位移,可优化周转斜盘发动机的动力学特性.
In order to optimize the dynamic characteristics of a swash plate type engine, the link force model, reaction torque model, contact torque model and spindle torque model were established.Based on the simulation analysis of each mathematical model, It is proposed to set the original circumferential displacement of 2 ° to ensure that the reaction torque is always positive. The change of the straight guideway restraint mechanism to the “∞” guideway restraint mechanism is to reduce the fluctuation of the contact torque and the spindle torque, The contact force between the roller and the guide groove ensures the good output characteristic of the engine shaft.The simulation results show that the power of the swash plate engine can be optimized by using the “∞” type guide groove restraining mechanism and setting the original circumferential displacement of 2 ° Learn characteristics.
