轻型货车桥壳振动特性分析
Vibration Characteristics Analysis of Light Truck Axle Housing
摘要
Abstract
In order to analyze the vibration characteristics of the axle housing.The finite element model of the axle housing was built by using finite element software,and modal analysis of the axle housing was made by using the Lanczos method.The modal test of the axle housing was carried out by using LMS test system,and the modal proportion factor (MCF) and the modal assurance criterion (MAC) ensured the reliability of the modal test.Comparing the frequencies and modal shapes of the modal analysis and modal test of the axle housing,the first five modal frequencies error were less than 5％ and the modal shapes were consistent.The modal frequencies of axle housing were away from the excitation frequency of the road,and the resonance failure would not occur.The vibration amplitude of the transition between the middle triangular plate and the axle housingl of the axle wrapped part of the axle housing was larger.Research results show that the axle housing finite element modeling is accurate,and lays a good foundation for the dynamic simulation of axle housing,static strength analysis and fatigue analysis.关键词
