【摘要】 轴向柱塞泵工作过程中,滑靴会在倾覆力矩作用下相对于斜盘表面形成一定的楔形油膜,在油膜静压支承力和油膜动压效应和挤压效应作用下滑靴副楔形油膜压力场始终与滑靴所受的外力和外力矩处在动态的平衡中。本文采用一种新的研究方法对滑靴油膜动态特性进行研究,用牛顿迭代算法对滑靴受力/力矩情况和滑靴副油膜的耦合关系进行研究。在Matlab软件中以低层编程的方法揭示滑靴副楔形油膜动态特性,从而对滑靴副工作特性进行预测。更多还原

【Abstract】 In the process of axial piston pump working,because of overturning moments the wedge oil film will form between the slippers and swashplate,which makes the pressure field of slipper pads,produced by oil film’s hydrostatic bearing,dynamic pressure effect and film’s extrusion effect,and external forces and external moments are in a dynamic balance.This paper introduces a new method to study the dynamic characteristics of oil film,and study the coupling relationship between all the extern forces/torques exerted on the slippers and film properties by the damped Newton’s method numerically.In Matlab Soft through programming to study the oil film properties in order to predict the performances of slippers by simulating.更多还原
