摘要
车架作为汽车总成的一部分,行驶过程中会承受复杂交变载荷的作用,所以,对其强度和刚度的设计尤其重要。运用有限元法对车架进行分析。利用UG建立了金龙XMQ6608NE1客车车架结构模型,运用UG中有限元模块对车架进行有限元静强度分析,得出车架应力分布云图和位移云图。分析结果表明:最大应力值为165.21 MPa,最大位移为2.815 mm,在弯曲工况中,最大应力发生在车架首、尾部,相对于车架的总长度而言,最大位移变形量和最大应力均满足设计要求。
As part of the automobile,the frame will bear the complex alternating load during driving,so the design of its strength and stiffness is particularly important.The finite element method is used to analyze the frame.The frame structure model of Kinglong XMQ6608NE1 bus is established by UG;the finite element module in UG is used to analyze the static strength of the frame,and the stress distribution and displacement of the frame are obtained.The analysis results show that the maximum stress value is 165.21 MPa,and the maximum displacement is 2.815 mm.In the bending condition,the maximum stress occurs in the front and rear of the frame.In view of the total length of the frame,the maximum displacement deformation and maximum stress meet the design requirements.
