摘要: 通过详细分析航空柱塞泵排油过程中的过流面积变化,同时考虑油液的压缩性和柱塞泵的泄漏,建立了航空柱塞泵瞬时流量的非线性数学模型.提出了一种航空柱塞泵配流盘结构的动态优化方法,该优化方法以航空柱塞泵瞬时流量脉动幅值最小为优化目标,采用旋转矢量法对配流盘结构参数进行实时在线寻优.仿真结果表明:该动态优化方法具有很高的效率和实用性,为航空柱塞泵的结构优化设计和消震、降噪研究提供了有力的理论依据.

Abstract: Through the discharge area of aviation piston pump was calculated accurately, and the compressibility of oil and leakage of cylinder were considered, the nonlinear mathematical model of instantaneous flow rate was established. A dynamic optimization method of valve plate structure was proposed based on the nonlinear instantaneous flow model. The amplitude of instantaneous flow fluctuation was the objective function of the dynamic optimization method. With rotate-vector method, the structural parameters of valve plate were optimized on line dynamically. The simulation results indicate that the dynamic optimization method is high practical and efficient. This provides the theoretical foundation to the structural optimization of aviation piston pump, and the study of vibration elimination and noise reduction.
