摘　　要：为了提高燃气比例阀的性能以便于更好地对其进行推广应用,使用AMESIM软件对燃气比例阀进行仿真建模,并结合动态特性试验对影响比例阀性能的因素进行研究,结果表明操作阀下方至针阀阀口流动通道(18)直径、腔室q1体积、燃气入口调节器的弹簧刚度和主切断阀阀口面积对燃气比例阀动态性能的影响较为明显,但是其他的因素也不可以忽略。在模型正确的基础上,针对这些影响因素进行仿真分析,并对原燃气比例阀模型进行改进。仿真结果表明,改进后的模型在性能优于原模型。To improve the characteristics of the gas proportional valve and for a better application, simulation modeling with AMESIM software has been introduced to find the factors affecting its properties, and measures have been made to improve its characters, and results show that the performance of the new gas proportional valve improved is better than the old one.
