【摘要】：针对摆线转子泵理论流量计算复杂,经验公式精确度较低的问题,基于Creo/parametric将参数化建模技术引入到摆线泵流量计算中,建立了摆线泵容腔端面的参数化模型,通过建立测量特征计算出了泵的排量,通过与理论排量对比,验证了参数化模型精度高于经验公式精度,根据积分原理,建立了转子啮合运动中,容腔端面变化沿轴向的累积模型,通过敏感度分析建立了容腔端面对转子转角的变化率曲线,进而得到了泵的流量曲线,并通过和理论流量曲线对比,验证了曲线的正确性。
[Abstract]:According to the theory of cycloid rotor pump flow calculation is complex, the experience formula of the low accuracy problem, based on Creo/parametric parametric modeling technology is introduced into the cycloidal pump flow calculation, a parametric model of cycloidal pump chamber end, through the establishment of measurement characteristics to calculate the displacement of the pump by comparison with the theoretical displacement, verify the accuracy the parametric model is higher than the accuracy of empirical formula, according to the integral principle, established the meshing movement, the accumulation model of cavity face changes along the axial direction, through the sensitivity analysis of the cavity end face change of rotor angle curve is established, and then get the flow curve of the pump, and through the theory and flow curve comparison, verification the correctness of the curve.
