【Abstract】 A three_dimensional finite element model of the LCD machinery system of one kind of portable computers is developed to perform modal analysis and transient response analysis.Based on the results,main factors which affect the residual vibration response of the LCD system are found and studied.Residual vibration response of the LCD can be suppressed rapidly and significantly if structural parameters are modified properly.The results of dynamic measurement are in good agreement with that calculated by FEM.更多还原
