Research on the Structural Transfer Path of New Mechanical Elastic Wheel Vibration

Abstract

To explore the double buffer damping performance of a new mechanical elastic wheel vibration (MEW), the structural transfer path of MEW vibration was studied using the evaluation method of path transfer ratio and insertion loss. According to the transmission path of the wheel's exciting force, the model of wheel vibration transfer path system was established. Combined with the analysis results of modal test, the response of the each vibration transfer path system was analyzed quantitatively, and the contribution of each transfer path of the wheel vibration was qualitatively evaluated. The analysis results indicate that the two paths have higher transfer ratio in each order natural frequency, the transfer ratio and insertion loss of path 2 are greater than the path 1 in low frequency, the transfer ratio and insertion loss of path 1 are little with the path 2 in high frequency. The analysis results reflect the objective law of the actual vibration transfer characteristics of the MEW, and provide a reference for the MEW structure optimization.
