基于Hypermesh的洗扫车水箱有限元分析

水箱是洗扫车工作过程中供水系统的主要存储部件,其受力变形问题对整车的工作性能影响较大。为了实现水箱的结构优化,在分析水箱受力的基础上,利用Creo和Hypermesh软件,建立简化模型、划分网格、添加载荷与约束,得到水箱的应力应变云图;通过分析应力应变云图,得出水箱的最大应变出现在水箱的前侧下半部分,最大应力出现在零件间接缝处的结论。因此,通过采取水隔板均匀布置、水箱前板下端加撑进行加固、隔板人孔由方形改为圆形或椭圆形、增强零件间接缝处的焊接质量等措施,对水箱结构进行优化,进而增强了水箱的强度,提高了整车的工作性能。

Finite Element Analysis of Sweeping Vehicle Water-tank Based on Hypermesh

Water-tank is main storage components of washing water system in the process of sweeping vehicle, the problems about variation of water-tank influence on working performance of the vehicle. In order to achieve structure optimization of the water-tank, this paper using Creo and Hypermesh software to build a simplified model, to mesh, to add load and constraint, which obtain the stress strain cloud diagram of the water tank on the basis of the analysis of the tank force. Through the analysis of stress and strain contours of maximum strain appear in the water tank on the bottom half of the side, and the maximum stress appeared in the conclusion parts between the joint. Therefore, the structure optimization of water-tank by adopting baffle uniform layout, reinforce the lower end of the front plate of the water tank, clapboard manhole from square to round or oval, juncture place between parts of welding quality measures, so that saving the cost of enterprise, enhance the competitiveness of enterprises.
