Abstract
Aiming at the problem of testing time consuming and low accuracy of transfer function estimation in the traditional TPA method, an improved TPA method is presented based on a new transfer function estimation method.Adopting the improved TPA method, the three-point suspension of powertrain was analyzed and a contrast simulation experiment was made.Since the new transfer function estimation method can eliminate the influence of the random noise, the estimation accuracy is enhanced.The improved TPA method elides the car body impendence testing and reduces the testing time.The simulation results show that the improved TPA method is viable.关键词
