Analysis the impact of tension on automobile synchronous belt transverse natural frequency

Abstract

Abstract. The vibration of belt in the process of automobile synchronous belt transmission directly influence transmission smoothness, and produce noise and affect the service life of the belt. In this paper, through the establishment of mathematical model of belt transverse vibration in the process of synchronous belt transmission, solving impact of tension on transverse vibration natural frequency; As the same time, designing a synchronous belt transverse vibration natural frequency measuring device in order to measure the transverse vibration natural frequency when the tension is from 300N to 1000N, so as to verify the mathematical model about impact of tension on transverse vibration natural frequency, provide the foundation for choice of tension in the process of automotive multi-pulley synchronous belt design, and have a certain significance on reducing the noise in the transmission process and prolonging the service life of belt .
