摘要
在可伸缩式车载行李架结构设计的基础上,参照车载行李架的正常工作环境,基于ANSYS-Workbench结构仿真计算平台对相关运行工况开展详细地分析校核.结构静力学分析结果表明,全伸、半伸、全缩时最大应力和形变均低于设计阈值;考虑车辆在山区或颠簸路面行驶可能引发的车载行李架振动破坏,进行车载行李架模态分析,获取车载行李架在不同伸缩状态下的振型和固有频率,为后续车载行李架的设计优化提供了理论参考.
A structural design of a retractable on-board luggage rack is put forward.According to normal working environment of on-board luggage racks,relevant operating conditions are analyzed and verified in detail based on an ANSYS-Workbench structural simulation calculation platform.The results of structural static analysis show that maximum stress and deformation of full extension,half extension and full shrinkage vehicle luggage rack are all below the design threshold.In addition,considering the vibration damage of the on-board luggage rack that may be caused by vehicles driving in a mountainous area or on a bumpy road,the modal analysis of the on-board luggage rack is carried out accordingly.And vibration shapes and natural frequencies of the on-board luggage rack under different extend states are obtained,which can provide a theoretical reference for future design optimization of on-board luggage racks.
