摘　　要：利用AMESim软件分别建立了某型柴油机液压调速器控制阀和执行机构的一维模型,研究了调速弹簧刚度、控制阀质量、飞块质量等参数对调速器性能的影响,以及优化前后控制阀和执行机构的响应特性。研究结果表明:调速弹簧刚度值为40(k N·m-1)时,控制阀响应时间最短;控制阀质量为0.03 kg时,震荡剧烈程度显著减小;飞块质量在0.052 kg时,可有效减少控制阀响应时间;优化前调速器响应时间为3 s,优化后为0.1 s。优化后的调速器控制阀以及执行机构能够很好地满足准确性和快速性的要求。One-dimensional models of the controlling valve and actuator were established respectively based on AMESim to study influences of the governing spring stiffness, controlling valve mass and fly- weight mass on performance of speed governor and response characteristics of the controlling valve and ac- tuator before and after optimization. Results showed that, the minimum response time of the controlling valve appeared when the governing spring stiffness was 40 （ kN m - 1 ）. When the controlling valve mass was 0.03 kg, the intensity of shock decreased dramatically. When the flyweight mass was 0.052 kg, the response time of the controlling after optimization while it was 3 valve reduced s before. The effectively. The response time of speed governor was 0.1 s optimized controlling valve and actuator of speed governor could meet the requirements of accuracy and rapidity well.
