摘要： 采用LSDYNA软件对某标杆车的滑移门保持件进行仿真分析,并根据国家法规GB15086—2013的要求进行了试验验证。对滑移门系统的中导轨、挂钩和后锁结构布置进行参数化设计,并结合最优拉丁超立方采样方法和径向基函数神经网络模型构建车门与门框最大分离距离的近似模型。最后,采用第二代非支配遗传算法(NSGA-II)对中导轨、挂钩和后锁高度方向的距离进行多目标优化。结果表明:车门与门框上端和下端最大分离距离分别为65.42和65.99 mm,导轮未从导轨中脱开,且B柱和C柱侧加载板总位移量均小于300 mm,保持件性能满足国家标准的要求。

Abstract: A simulation analysis on the sliding door keeper of a benchmarking car is conducted with software LSDYNA, and the verification test is performed in accordance with the requirements of GB15086—2013. Then the parametric design of middle guide, hook and rear lock structural layouts are carried out, and the approximate model for the separation distance between the door and frame is built based on optimum Latin hypercube sampling method and RBF neural network model. Finally, a multi-objective optimization for the distances of middle guide, hook and rear lock along vertical direction is completed by using NSGA-II algorithm. The results show that the maximum upper and lower separation distances between sliding door and its frame is 65.42 and 65.99 mm respectively, and the guide wheel does not fall off from guide rail, with the total displacements of both B and C column side loading plates are less than 300 mm, meeting the performance requirements of door keeper according to the national standard.

Key words: sliding door keeper, structure layout, multi-objective optimization
