摘要
压填机构是自装卸式垃圾车的核心部件,在垃圾装载过程中发挥关键作用,然而在实际工作中常因其刚度和强度不足出现结构变形,甚至失效的问题。基于此,首先介绍了滑动-转动型压填机构的结构组成和工作原理,并分析其在极限工况下的受力情况;然后基于有限元理论,利用INVENTOR软件对滑动-转动型压填机构做结构静力学仿真,依据仿真计算结果找出薄弱部位后优化其结构;最后将优化后的滑动-转动型压填机构进行相同条件下的静力学仿真,与优化前的结果对比,刚度和强度显著提升,并能满足极限工况下的受力要求。
The compaction mechanism is the core component of self-loading garbage trucks,playing a crucial role in the garbage loading process.However,in practical work,structural deformation and even failure often occur due to insufficient rigidity and strength.The article first introduces the structural composition and working principle of the sliding-rotating compaction mechanism,and analyzes its force conditions under extreme working conditions.Then,based on finite element theory,the structural statics simulation of the sliding-rotating compaction mechanism is carried out using INVENTOR software.According to the simulation results,the weak parts are identified and the structure is optimized.Finally,the optimized sliding-rotating compaction mechanism is subjected to statics simulation under the same conditions.Compared with the results before optimization,the rigidity and strength are significantly improved,and it can meet the force requirements under extreme working conditions.
