摘　　要：填装器作为后装压缩式垃圾车重要结构部件,不仅起到封闭箱体的作用,而且是刮板、滑板平滑运动,实现垃圾压缩功能的重要保证。垃圾车使用工况恶劣,良好的强度性能是填装器能够正常使用的前提。针对新型后装压缩式垃圾车搭载的填装器结构,施加填装器开启和关闭状态下的载荷,对其进行有限元分析,求得填装器结构应力、位移分布云图,进而预知危险位置,并针对不满足强度性能区域进行结构改进,提升结构强度性能,降低填装器失效风险。The tailgate,as an important structural component of the rear loaded compression refu se collecto r,not only plays the role of closing the body,but also is an important guarantee for the smooth movement of the scraper and skid to achieve the function of refuse compression.As the refuse collector is used in harsh working conditions,good strength performance is a prerequisite for the normal use of the tailgate.For the structure of the tailgate mounted on the new rear loaded compressed refuse collector,the loads in the opening and closing states of the tailgate are applied,and a finite element analysis is carried out to obtain a cloud map of the stress and displacement distribution of the tailgate structu re,then predict the dangerous locations,and make structural improvement for the areas that do not meet the strength performance to improve the structural strength performance and reduce the risk of tailgate failure.
