Estimation method for vehicle interior noise and vibration contribution estimation by Operational and Component TPA - Basic consideration employing simple vehicle model -

An analytical method was considered for estimating vehicle interior noise and vibration identifying main contributors in case the power source is replaced by combining operational (OTPA) component transfer path analysis (CTPA) methods. A simple model equipped with motor small test bench prepared basic consideration this study. In method, OTPA CTPA were applied to following three steps. first step, at condition obtain contribution functions from multiple reference points response point. second steps, another on blocked force. Subsequently, point (motor attachment point) estimated using force function model. Finally, integrated into model, calculated. Through verification bench, observed be accurately method. addition, high contributing also indicated correctly.
