摘要
主要对某公司一款新能源客车车架进行强度和刚度分析:以该种混合动力型城市客车的车架为分析研究对象,基于有限元分析方法,利用三维建模软件CATIA对该款客车的底架进行建模,再通过有限元分析软件ANSYS对所导入的客车车架模型进行多工况的静力学分析.分析该车架在 3 种工况(匀速行驶、紧急转弯和紧急制动)下所受的应力与变形情况,对车架的强度及刚度进行校核,为客车的行驶安全性提供保障.
Abstract
With the continuous enhancement of China's comprehensive national strength,people's quality of life is getting higher and higher.At the same time,considering environmental pollution and energy consumption,new energy vehicles have gradually become an important means of transportation in today's society.By using finite element method to analyze and detect vehicles that are about to be put into the market,it can optimize the design deficiencies,provide certain guarantees for passenger safety,and reduce design and manufacturing costs.This article mainly analyzes the strength and stiffness of a new energy bus frame from the XXX company.By taking the frame of this hybrid city bus as the research object,and based on the finite element method,the 3D modeling software CATIA is used to model the chassis of the bus,and then use the finite element software ANSYS to conduct a static analysis of the input bus frame model under multiple working conditions.By analyzing the stress and deformation of the frame under three operating conditions(constant speed driving,emergency turning,and emergency braking),the strength and stiffness of the frame are verified to provide assurance for the driving safety of the bus.
