摘要
针对PLA70压力补偿控制型变量柱塞泵建立其配流盘单个柱塞内油液压力梯度(压力)变化的数学模型,定量分析了控制体在预升压过程中未开槽和开三角槽时,在一定转速下、不同接触角度时模型的压力梯度(压力)与转角变化之间的关系,在用Matlab对该模型进行仿真,得出三角槽过流面积的最佳结构参数。
Aim at PLA70 press compensation control variable piston pump,build math model on press grads (press) of port plate's single piston,make quantitative analysis when it has damping groove or not on the relationship between press grads (press) and corner of the eduction oil cavity and damping groove when the rotate speed is constant and the osculant corner is different during beforehand rising press,use Matlab to simulate the math model,enduce the best frame parameter of the damping groove's passing acreage.
