摘要

摘要: 为研究不同轴径比转子系统对航空泵功重比的影响, 建立了十一柱塞航空液压泵缸体、传动轴、支撑轴承这3部分组成的转子系统。首先, 建立了泵排量、流量和功率的计算模型, 基于排量不变原则, 设计了16组不同轴径比的航空柱塞泵转子系统, 并对缸体强度进行理论校核; 然后建立了转子系统的功重比计算模型; 最后, 通过对缸体强度有限元仿真计算和功重比理论计算, 得到了重构建的不同轴径比缸体能够满足转子系统的强度要求和不同轴径比转子系统对功重比的影响规律。为后续航空液压泵的不平衡响应分析以及缸体结构优化设计提供了理论支撑。

Abstract: In order to study the influence of rotor systems with different shaft diameter ratios on the power-to-weight ratio of aviation plunger pumps, a rotor system consisting of three parts of the eleven-plunger aviation hydraulic pump cylinder block, drive shaft and support bearing is modeled in this paper. First, a calculation model for pump displacement, flow and power is established. Based on the principle of constant displacement, sixteen groups of aviation plunger pump rotor systems with different shaft diameter ratios are designed, and the cylinder strength is theoretically checked. Then, the power-to-weight ratio calculation model of the rotor system is established. Finally, through the finite element simulation of the cylinder block strength and the theoretical calculation of the power-to-weight ratio, it is concluded that the rebuilt cylinder blocks with different shaft diameter ratios can meet the strength requirements and requirements of the rotor system. The influence law of the rotor system with different shaft diameter ratios on power to weight ratio is obtained, which provides theoretical support for subsequent analysis of unbalanced response of aviation hydraulic pumps and optimization design of cylinder structure.
