摘要
针对双元动力发动机存在的结构复杂和非线性磁路难以建立精确优化模型等问题,本文基于正交试验,对永磁活塞机械电力发动机定位力进行改进分析。研究了永磁体沿磁化方向长度、气隙宽度、齿槽槽宽对定位力的影响,利用正交试验法对各参数进行优化,并以定位力幅值最小为目标,得到发动机电动力结构的最优尺寸,同时对仿真结果进行极差分析,得到主要结构参数对目标值影响的权重顺序。分析结果表明,优化后定位力幅值为5.07 N,与优化前相比,降低了48.9%,验证了优化方法的有效性,有效改进了永磁活塞机械电力发动机结构的定位力。该研究为永磁活塞机械电力发动机的设计优化提供了理论依据。
Aiming at the problems of complex structure and non-linear magnetic circuit that are difficult to establish an accurate optimization model of the dual-element power engine,this paper improves the analysis of the positioning force of the permanent magnet piston mechanical electric engine based on orthogonal tests.The effects of the length of the permanent magnet along the magnetization direction,the air gap width and the slot width of the tooth slot on the positioning force are investigated,and the orthogonal test method is used to optimize each parameter to obtain the optimal size of the engine electrodynamic structure with the minimum positioning force amplitude as the target,while the extreme difference analysis is performed on the simulation results to obtain the weight order of the influence of the main structural parameters on the target value.The analysis results show that the optimized positioning force amplitude is 5.07 N,which is 48.9%lower than that before optimization,verifying the effectiveness of the optimization method and effectively improving the positioning force of the permanent magnet piston mechanical electric engine structure.This study provides a theoretical basis for the design optimization of the permanent magnet piston mechanical electric engine.
