Analysis on Random Vibration and Impact Response of Vehicle-Borne Electronic Chassis
Abstrak
AbstractIn order to meet lightweight design requirement of vehicle-borne electronic chassis, vibration and impact response of chassis was analyzed based on the theory of random vibration and transient impact dynamics. Considering the influence of heat dissipation, corrosion resistance, material strength and economy of processing, weight reduction design was carried out according to vibration and impact response stress nephogram of chassis. The computation results show that the weight of chassis frame decreased by 16.4% and the first-order modal frequency of chassis decreased by 14.2% after weight reduction. Impact response had a lag relative to input impact spectrum. The increase of vibration stress was obviously higher than that of impact stress in different directions, which was still less than the corresponding material yield strength. That is, the structural strength of chassis after weight reduction meets the requirements of vibration and impact resistant design. The research results can provide theoretical basis of electronic equipment lightweight design under vehicle vibration and impact environment.
