• In this study, target level setting method for reference signal of operational TPA was considered using principal component regression method. A principal component having high contribution to the response signal was selected and target levels of the reference signals were calculated using the principal component by principal component sensitivity analysis. In addition, a useful information obtaining procedure for countermeasure was proposed using analysis of principal component behavior. Principal component behavior analysis shows the vibration behavior at a principal component having high contribution to the response signal. By referring to the behavior, the vibration behavior that should be measured to reduce response signal vibration could be obtained. To verify the effectiveness of these methods, operational TPA with the new methods were applied to a small model vehicle. In the experiment, floor vibration was set as the response signal and nine measurement points such as motor attachment point were used as the reference signals.The reduction target levels of each reference signal were calculated by principal component sensitive analysis and the countermeasure was considered by the principal component behavior analysis. By referring to the analytical result, a countermeasure was performed actually. As a result, the floor vibration level was reduced almost same as the target level. Through these consideration and experiment, operational TPA could have more function in which the method could set the target of reference signals and suggest the countermeasure guideline in addition to performing contribution separation.
