摘要
为了降低重型自卸车货箱质量和车辆油耗,提高车辆运输效率,采用三维软件PRO/E建立重型自卸车货箱底板的应力分析有限元模型,并导入ANSYS Workbench中。利用ANSYS Workbench有限元仿真软件计算静态工况与动态工况下货箱底板的应力分布和变形量。基于静态与动态有限元仿真结果,提出了正三角布置重型自卸车货箱底板中部横梁的轻量化设计方案,并对改进设计后的货箱底板变形量进行仿真,验证轻量化设计方案的合理性。研究结果显示:在满足货箱底板应力要求和强度要求的前提下,通过对货箱底板的轻量化设计,使货箱底板总质量降低20. 88%,实现了轻量化的目标。
In order to reduce the weight and fuel consumption of heavy dump trucks and improve transportation efficiency,the three-dimensional software PRO/E was used to establish the stress analysis finite element model of the heavy dump truck cargo floor and imported into ANSYS Workbench.The ANSYS Workbench finite element simulation software is used to calculate the stress distribution and deformation of the bottom plate of the tank under static and dynamic conditions.Based on the static and dynamic finite element simulation results,a lightweight design scheme for arranging the middle beam of the heavy dump truck cargo box floor with a positive triangle is proposed,and the deformation of the improved cargo box floor is simulated to verify the rationality of the lightweight design.The research results show that under the premise of meeting the stress requirements and strength requirements of the cargo box floor,the lightweight quality of the cargo box floor is reduced by 20.88%,and the goal of lightweight is achieved.
