基于仿真分析的活塞冷却喷嘴主要结构参数对打靶效率的影响
为探究活塞冷却喷嘴打靶准确率受哪些因素影响，先是建立了二维模型，并通过Fluent模拟打靶过程，针对活塞冷却喷嘴参数繁多，控制变量法仿真过于繁琐的问题，首先结合正交分析减少实验次数，并通过极差分析和方差分析找到主要影响参数，通过主成分分析和多因素分析验证主要影响参数的信息贡献率，获得了活塞冷却喷嘴各个参数对打靶准确率的影响，并通过再次修改主要参数验证了仿真结论。最后根据回归分析获得了活塞冷却喷嘴参数对油束扩散角度和打靶准确率的回归方程，及最主要影响因素。
To investigate the factors affecting the accuracy of the piston cooling nozzle in the shooting process, a two-dimensional model was first established, and the Fluent software was used to simulate the shooting process. Due to the large number of parameters involved in the piston cooling nozzle and the complexity of controlling variables in simulation experiments, the orthogonal analysis was employed to reduce the number of experiments, and the main influencing parameters were identified through range analysis and variance analysis. The information contribution rate of the main influencing parameters was verified by principal component analysis and multiple factor analysis, and the effects of various parameters on the shooting accuracy were obtained. The simulation conclusion was further verified by modifying the main parameters. Finally, the regression equation of the piston cooling nozzle parameters on the diffusion angle of the oil beam and the shooting accuracy, as well as the most important influencing factors, were obtained through regression analysis. Overall, this method uses numerical simulation and statistical analysis to efficiently and reliably identify the main influencing parameters and their effects on the shooting accuracy of the piston cooling nozzle, and provides guidance for its optimization.
