摘要
将虚拟样机技术应用于轴向柱塞泵球铰-回程盘相对运动关系的研究。根据柱塞泵的物理模型参数,并利用直角坐标系和球面坐标系间的转换关系,建立球铰-回程盘相对运动关系的数学模型;基于MSC.ADAMS和AMES im环境,通过构建柱塞泵固液耦合的虚拟样机模型来模拟二者间的实际相对运动情况。综合两种模型的分析结果表明:回程盘锥度、球铰半径、泵轴转速以及斜盘倾角是影响球铰-回程盘相对运动轨迹及相对运动速度的重要参数。
The application of virtual prototype on the relative motion between the ball guider and retainer within axial piston pump was introduced. According to the physical model parameters of piston pump and the conversion relation between fight angle coordinate and spherical coordinate, mathematical model of the relative motion was built. Based on the MSC. ADAMS and AMESim environment, the real relative movement between them was simulated by constructing the virtual prototype of solid-fluid coupling model. By comparing analysis of the two models, the results show that retainer taper, ball guider radius, axis rev and swash plate angle are important paranleters which affect the relative motion trajectory and speed between the ball guider and retainer.
