摘要
随着经济发展和人民生活水平的提高,汽车设计多样性需求日益受到用户的重视。掀背式后举门和常规后盖相比能够满足更多的功能需求,促进了后举门在乘用车领域的应用。后举门依靠气弹簧辅助用户完成开合动作,气弹簧力不可避免地造成了后举门的变形。常规后举门匹配方法在实车造出以后才进行评估,时间节点偏晚,设计更改难度大,成本高。提出采用有限元模拟对后举门气弹簧变形进行评估的方法,可以在早期驱动结构改进,也可以为匹配优化提供参考。与实测数据的对比表明,采用有限元模拟方法评估效果良好。
With the economic development and the improvement of people’s living standards,the demand for the diversity of automobile design is increasingly valued by users.Compared with conventional backoo cover,lift gate can satisfy more function requests and becomes popular in car structure design.Gas spring affects the result of lift gate matching and becomes one of the factors that must be considered.In conventional lift gate matching method,the assessment is carried on after the real vrhicle built,design optimization is difficult and optimization cost is high.Numerical simulation can be used to evaluate the gas spring deformation,which can drive structural improvments in the pre?projects and provide support during matching.Through comparsion of mesaures data,the gas spring deformation by numerical simulation shows the effectiveness.
