新能源汽车车身结构设计及仿真分析

New Energy Vehicle Body Structure Design and Simulation Analysis

通过对燃油汽车和新能源汽车的车身构造进行比较,分析两类汽车车身的区别;以新能源汽车车身作为研究对象,采用CATIA软件对新能源汽车车身进行三维模型设计;应用ANSYS对车身模型进行静态分析,验证设计的新能源汽车车身满足车辆行驶要求的静刚度,最后对设计的车身进行了振动与噪声模态计算。通过分析最终证明,所设计的新能源汽车车身具有较好的综合性能。

The investigation encompasses a comparative analysis of the structural configurations in conventional petrol-driven vehicle and electric vehicle,examining the unique characteristics of each.With a primary emphasis on the electric vehicle’s architecture,a detailed three-dimensional modeling of the electric vehicle’s chassis is executed utilizing CATIA software.Following this,a static analysis is performed on the modeled structure through ANSYS,ensuring the engineered electric vehicle body exhibits sufficient static rigidity for secure operational purposes.Furthermore,a comprehensive vibration and noise modal analysis are conducted on the designed chassis.These analyses conclusively validate the exceptional overall performance of the proposed electric vehicle body design.
