Research And Development Of Electronically Controlled Hydraulic System For Garbage Truck Compression Mechanism

In recent years, rear loading compression garbage truck was very rapid in the domestic and foreign development. Organization of compression is one of its core parts.This article first carries on the elaboration from the classification, structure as well as the domestic and foreign garbage truck’s garbage truck current development and tendency,points out that the domestic garbage truck’s level in development application is irregular and costs high. Next, the article reduces the classification and compression of principle of work organization to the rear loading garbage truck carries on the elaboration, and compresses the organization hydraulic system to analyze to the traditional breech loading garbage truck, points out that its efficiency is low, the environment difference and manpower and resources are many and other shortcomings.Based on this, one kind of new rear loading garbage truck compresses the organization electrically controlled hydraulic system, and analyzes to this system, with tradition compares systematically,points out that it saves manpower and resources, accurate electric control and other merits.Through the consult literature as well as this hydraulic system’s practical work process selection appropriate cone-way valve and overflow valve, the article has developed electromagnetism switch valve, three six cross valve and forerunner proportion overflow valve and so on, carries on the structural design to each valve block, and assembles the overall assembly drawing. Finally, with the aid of the AMESim software, the article establishs each valve block the simulation model, and has established the appropriate simulation parameter. With the aid of the Matlab software, the article establishes electrically controlled module. To compressing the organization oil duct carries on the simulation analysis through the AMESim-Simulink union simulation, the article obtains the transient response curve of scraper and slide, the analytic curve may know, establishes the compression organization electrically controlled hydraulic system steady-state characteristic to be good, the reliability is high.
