【摘要】：针对应用多作用定子导轨结构的径向柱塞泵,通过对柱塞副在等加速运动规律定子曲线下的动力学分析,研究了不同幅角分配方案对泵性能的影响。研究结果表明:定子曲线的幅角分配对度加速度、度速度、压力角、缸体受力、接触应力等性能有很大的影响,且幅角分配不对称系数约等于2,等速区幅角值是等加速区幅角值的0.9~1倍时,泵的综合性能相对最佳;吸排油过程中油液速率的许用值和接触应力的最大值分别可以作为等速区和等减速区幅角设计的参考基准之一。
[Abstract]:Aiming at the radial piston pump with multi-action stator guideway structure, the effect of different amplitude and angle distribution schemes on the pump performance is studied through the dynamic analysis of the piston pair under the stator curve of the law of equal acceleration motion. The results show that the distribution of amplitude angle of the stator curve has great influence on the performance of degree acceleration, degree velocity, pressure angle, cylinder block force, contact stress, etc. When the asymmetry coefficient of amplitude and angle distribution is about 2 and the amplitude angle of isokinetic zone is 0.9 times of that of equal acceleration zone, the comprehensive performance of pump is relatively best. The allowable value of oil flow rate and the maximum contact stress can be used as one of the reference datum for the amplitude and angle design of the isokinetic region and the equal deceleration zone respectively.
