| With the gradual expansion of the size and the daily throughput of the port,the application of the front crane in the port is more and more extensive.Therefore,it is an important way to improve the quality of the port trade by developing a higher quality of the crane.At present,the domestic container crane technology is still lagging behind foreign enterprises in the same industry,making China’s continuous introduction of foreign cranes to meet the huge demand for port cargo.Due to the existence of a large number of easy loss of hydraulic components,maintenance difficulties and high freight costs,affecting the development of enterprises.Therefore,the in-depth detection and research based on the hydraulic components of the front suspension has a profound impact on the development of the port freight.The positive hydraulic system plays an important role in the normal operation of the whole machine.Therefore,the research on the simulation of the hydraulic system is very important to the stability of the front crane.In order to study the influence of structural parameters of hydraulic components on the stability of the crane.This paper describes the structure and the working principle of the hydraulic system and the working principle of each part of the front suspension crane.Then,using AMESim software Mechanical,Hydraulic and HCD module,build reachstacker load sensitive variable pump and front jib crane frame,front differential valve balance valve and reachstackers control simulation model of the hydraulic system of the swing of the spreader.Through the simulation calculation,the influence of the structural parameters of the hydraulic components on the stability of the whole system is studied.The influence of the structural parameters of hydraulic components on the stability of the system is studied.The theoretical basis is provided for the development of the components of the front end of the container,which is easy to be lost and found and developed. |
