PROBLEM TO BE SOLVED: To improve accuracy in identification of input power, in the acoustic vibration analysis for a vehicle, which uses a statistical energy analysis, in term of an acoustic vibration analysis method and an acoustic vibration analysis device for a vehicle.SOLUTION: The measured value of energy in at least one of measurement elements is obtained (A20), and a design variable corresponding to the measurement error of the energy is set (A30). Additionally, based on the energy balance between the elements with the energy of the measurement element is restrained using at least the addition value of the design variable and the measurement value, provisional power input to each element is calculated (A40, A50). Based on the provisional input power and the design variable corresponding to this, power input to each element is identified (A60). |
