Article Preview

Abstract:

This paper explains and demonstrates how to construct integration simulation model of exavtor operator based on modelica language. The paper firstly introduce the history of modelic language and application in production design; secondly the paper construct exavtor operator dynamics model by D-H method and construct operator’s modelica model by dymola soft; then the paper analyse the hydraulic system of operator, and construct hydraulic simulation model which integrate to operator mechanism system; at last the paper gives simulation results of vauious operating mode. Because of consideration in coordination of mechanism and hydraulic of operator,the simulation results approach actual working process,and improve the exavtor’s design efficiency and reliability.
