摘要
基于新能源汽车聚焦解决售价高和续航里程短特点,新能源汽车开发需要严格控制开发成本和整车自重,部分传统车解决方案不适用新能源汽车开发问题,需要重新优化整车设计和问题解决方案,文中以控制门下垂解决方案为案例,以Hypermesh 12.0,Abaqus 6.14-1等仿真软件为分析工具,结合试制车实物验证,提出针对新能源汽车控制门下垂经济实用解决方案,通过控制关键焊点和典型小件可以有效控制汽车门下垂,试制车验证结果表明方法有效。提示工程设计专业技术人员,新能源汽车与传统车开发特点差异影响问题解决方案制定。
Based on the characteristics of new energy automobile focusing on resolving the selling price and endurance mileage,the development of new energy automobile needs to strictly control the development cost and the weight of the whole vehicle.Some traditional vehicle solutions are not suitable for new energy automobile facing new problems,and need to reoptimize the vehicle design and problem solutions.In this paper,the solution of controlling door sag is presented.Taking Hypermesh 12.0,Abaqus 6.14-1 and other simulation software as analysis tools,combined with the physical verification of the trial vehicle,an economical and practical solution for the sag of the control door of the new energy vehicle is proposed.The sag of the control door can be effectively controlled by controlling key welding points and typical small pieces.The test results show that the method is effective.It is suggested that the differences between the development characteristics of new energy vehicles and traditional vehicles will affect the formulation of solutions to the problems for engineers and technicians in engineering design.
