The purpose of this study is to optimize the acceleration operational data at suspension link pivotal point for Transfer Path Analysis (TPA). Generally, acceleration signal obtained at pivotal point contains not only fore-aft, radial, and tangential direction component but also undesirable rotational signal. An experimental approach to eliminate undesirable rotational signal is studied by adding extra accelerometer on the opposite side of where the original pivotal point acceleration is obtained. The acceleration signals at suspension link pivotal point are compared to one another then, averaged with phase. This averaged acceleration spectrum is then validated through TPA results.
