以锥形转子球面斜盘轴向燃油柱塞泵为研究对象,在分析滑靴油膜设计中的摩擦功率损失、泄漏功率损失、容积效率随滑靴的机械结构参数变化的基础上,基于遗传算法对上述多变量、多目标优化问题进行计算.权重系数法优化结果表明:优化后燃油柱塞泵设计点的摩擦功率损失和泄漏功率损失减少了7%左右,容积效率略微提升,并且优化得到的机械结构参数在不同转子转角和柱塞倾角的情况下也显示出性能上的优势,从而证明了多目标遗传算法对设计航空燃油柱塞泵油膜静压润滑是一种有效的方法.
Taking the tapered rotor spherical swash plate axial fuel plunger pump as the research object, based on the analysis of the frictional power loss, the leakage power loss and the volumetric efficiency of the sliding shoe oil film design, with the change of the mechanical structural parameters of the sliding shoe, The optimization of the multivariable and multi-objective optimization problems is carried out.The optimization results of the weight coefficient method show that the frictional power loss and leakage power loss at the design point of the optimized fuel plunger pump are reduced by about 7%, and the volumetric efficiency is slightly increased, and the optimized The mechanical structure parameters also show the performance advantages under different rotor angles and plunger inclination, which proves that the multi-objective genetic algorithm is an effective method to design the hydrostatic lubrication of the aerofluid piston pump.
