Response Analysis of a Combat Platform System to Pavement Excitation

When the combat platform is running on the road at a constant speed, it will have different vibration responses due to the different speed and road roughness. Road excitation is the main vibration source of the vibration system of the combat platform. Obtaining accurate road information is the key to analyze and evaluate the impact of the combat platform system on the road. In this paper, based on the fitting expression of road power spectral density recommended by GB/T7031-2005 and Simulink simulation software, the simulation model of combat platform is established when it is moving, and then the time-domain response of 1/2 combat platform system dynamics model under road random excitation is analyzed. The influence of road roughness and running speed on the vibration response of platform body is analyzed. It provides a theoretical basis for the design and structure optimization of combat platform.
