The Simulation Research on Controlling Noise Source of Self-propelled Artillery Engine

摘要

The kinetic simulation system for whole diesel engine system of the self-propelled gun has build up by using Simulink tool of Matlab software. On the basis of simulation on the model under disturbance of sine and white noise signal, the analyses on the results of the curves about torque and rotational speed output from prove that the model has high reliability, and set-up of the model will provide the way for deep simulation researches of engine. Through using dynamic simulation model, vibration conditions of output rotating speed and torque of engine caused by loud distribution and intake link are investigated, and vibration-reducing control has been also investigated under sine signal and white noise signal disturbance, meanwhile PI close-ring technology is used, the curve results of output torque and rotating speed are indicated that vibration-reducing is exhibited with high performance, and pave the way to further realize vibration control of self-propelled artillery engine.
