摘要：

以车用电控汽油喷油器为对象，从电磁学、机械动力学的基本原理出发建立了电控汽油喷油器工作过程的计算模型，依据通电后线圈电流的变化特点得出了动态响应特性与磁路结构参数的函数关系。以提高动态响应特性为目标，采用多目标模拟退火算法（MOSA）对磁路结构参数进行了优化。电磁场仿真结果表明，优化后的磁力线和磁感应强度分布更加合理。实验测试结果表明,优化后的汽油喷油器的开启延迟时间和关闭延迟时间分别比优化前缩短29.41%和29.23%。仿真和实验结果均验证了优化算法的有效性。

Abstract:

Taking the automotive electronic gasoline injector as an object,a computational model of the injector's working process was established from the basic principles of electromagnetism and mechanical kinetics. The relationship functions were derived between dynamic response characteristics and magnetic circuit structure parameters based on the coil current change after power on. As the goal to improve the dynamic response characteristics, the magnetic circuit structure parameters of the injector were optimized with the help of MOSA algorithm. The electromagnetic field simulation results show that the magnetic flux and magnetic induction intensity distribution are more reasonable after the injector optimized; the experimental results show that the opening delay time and closing delay time of the optimized injector are reduced respectively by 29.41% and 29.23% compared with before optimization. Above results verify the effectiveness of the optimization algorithm from simulation and experiments.

Key words: gasoline injector;magnetic circuit structure;dynamic response;multi-objective simulated annealing(MOSA) , algorithm
