Abstract Aiming at the problems of insufficient oil suction and slow system response caused by the unreasonable parameters of the distribution check valve in single plunger pump system, a multi parameter optimization method based on linear regression was proposed. Firstly, the simulation analysis of single plunger pump system was carried out by AMESim software, and the relationship between different check valve parameters (spring pre-tightening force, spring stiffness and valve core mass) and oil inlet flow was discussed by using MATLAB fitting toolbox. Then, on the basis of using the principal component analysis method to eliminate the correlation between the parameters, taking the oil inlet flow as the dependent variable, the spring pre-tightening force, spring stiffness and valve core mass as the independent variable, and the value range of each parameter as the constraint condition, a check valve parameter optimization model based on linear regression was established, and the genetic algorithm was used to optimize the solution. Finally, according to the parameters of the check valve before and after optimization, the simulation analysis and experimental verification of the single plunger pump system were carried out. The simulation results showed that the oil inlet flow was increased by 21.3% after optimization; the experimental results showed that the actual oil inlet flow was increased by 16.8% after optimization. The research shows that the proposed multi parameter optimization method is an effective method, which can provide reference for the parameter optimization of the distribution check valve in single plunger pump system.

基于线性回归的单柱塞泵单向阀参数优化
针对单柱塞泵系统中配流单向阀参数不合理所导致的吸油不充分、系统响应慢等问题,提出了一种基于线性回归的多参数优化方法。首先,通过AMESim软件进行单柱塞泵系统仿真分析,并利用MATLAB拟合工具箱分别探讨了不同单向阀参数(弹簧预紧力、弹簧刚度和阀芯质量)与进油口流量的关系。然后,在利用主成分分析法消除各参数之间相关性的基础上,以进油口流量为因变量,弹簧预紧力、弹簧刚度和阀芯质量为自变量,各参数的取值范围为约束条件,建立了基于线性回归的单向阀参数优化模型,并采用遗传算法进行优化求解。最后,根据优化前后的单向阀参数,对单柱塞泵系统进行仿真分析和实验验证。仿真结果表明,优化后进油口流量提高了21.3%;实验结果表明,优化后进油口的实际流量提高了16.8%。研究表明,所提出的多参数优化方法是一种有效的方法,可为单柱塞泵系统中配流单向阀的参数优化提供参考。
