基于ANSYS的后装压缩式垃圾车刮板有限元分析

Finite Element Analysis of Rear Loading Compression Garbage Truck Scraper Based on ANSYS

刮板是后装压缩式垃圾车用于收集垃圾的主要工作部件,其受力变形问题对整车的工作性能影响较大。为了实现轻量化设计,在分析刮板受力的基础上,利用NX和ANSYS软件,建立简化模型、划分网格、添加载荷与约束,得到刮板的应力应变云图;通过分析应力应变云图,得出刮板的最大应变出现在刮板下半部分的中部,最大应力出现在零件间接缝处的结论。因此,通过采取筋板不均匀布置、刮板两侧减重、增强压板接缝处的焊接质量,对刮板结构优化,进而节约企业成本、提高竞争力有较大的好处。

Scraper is the main working part of garbage collection in the rear loading compressed garbage truck,and the stress deformation has large influence on working performance of the vehicle. In order to realize the lightweight design,based on the analysis of the force of the scraper,the simplified model is established by NX and ANSYS software,and the stress and strain nephogram are obtained by dividing the mesh and adding the load and the constraint. By analyzing the stress and strain nephogram,the maximum strain of the scraper appears in the middle of the lower half of the scraper,and the maximum stress appears at the indirect joint of the parts. Therefore,through the uneven arrangement of the stiffened plate,the weight reduction on both sides of the scraper and the enhancement of the welding quality at the joint of the pressboard,it is of great benefit to the optimization of the scraper structure,thereby saving the cost of the enterprise and enhancing the competitiveness.
