[Abstract]:In recent years, the rear compressing garbage truck is developing rapidly at home and abroad, and the compression mechanism is one of its core components. In this paper, the classification and structure of garbage truck and the development status and trend of garbage truck at home and abroad are expounded, and it is pointed out that the level of development and application of domestic garbage truck is uneven, the cost is high and so on. Secondly, the classification and working principle of the compression mechanism of the rear loading garbage truck are explained, and the hydraulic system of the compression mechanism of the traditional rear loading garbage truck is analyzed, pointing out its shortcomings such as low efficiency, poor environment, more manpower and material resources and so on. On this basis, a new type of electronic hydraulic system for the compression mechanism of the rear loading garbage truck is proposed. The system is analyzed and compared with the traditional system. The advantages of this system are pointed out, such as saving manpower and material resources, accurate electronic control and so on. According to the reference of literature, according to the actual working process of the hydraulic system, the suitable one-way valve, relief valve, electromagnetic switch valve, three-position six-way directional valve, pilot proportional relief valve and so on are designed. The structure of each valve block is designed. And assemble the whole assembly drawing. Finally, with the help of AMESim software, the simulation model of each valve block is established, and the appropriate simulation parameters are set up, and the electronic control module model is established with the help of Matlab software. The transient response curves of the slide plate and the scraper are obtained through the simulation and analysis of the hydraulic system of the compression mechanism by AMESim-Simulink simulation. The analysis curve shows that the steady state characteristic and reliability of the electronic-hydraulic system of the compression mechanism are better and the reliability is higher.
