Abstract

This paper models and studies the dynamic characteristics of slewing system of 80T truck crane. Analyzing the composition and working principle of the hydraulic system, and building the model of slewing system based on AMESim, then testing the model. And the simulation analysis results indicate the factors which affect the dynamic characteristics of the system and propose the measures to improve them. The results show that adopting the bypass circuit makes the shock pressure reduced 18 percent when the system operates, besides, changing the system´s control strategy and installing one-way throttle enhance the stability of braking obviously.
