Abstract

Taking the Woodward´s UG-25plus electro-hydraulic governor for research object, this paper established mathematical model of the electro-hydraulic speed governing system of diesel engine. By means of simulink simulation, analyzed the main factors which affect dynamic characteristics of hydraulic actuator, emphatically Analyzed influence of damping ratio, natural frequency and flow gain of servo valve on dynamic characteristics of Hydraulic system, and analyzed the dynamic characteristics of the speed governing system of diesel engine and obtained coincide with experimental results. The research provides theoretic basis for improvement design of electro-hydraulic governor during localization.
