摘要

在多领域统一建模仿真平台MWorks下,采用Modelica语言建立液压起升机构的多场耦合仿真模型,对吊重瞬间离地起升这一典型工况进行动态仿真,分析液压起升机构的动态特性,以及变量泵容积调速系统在减小冲击方面的影响。结果表明,采用建立的仿真模型能够较好地模拟起升机构性能,反映液压耦合的作用,为起升机构的设计提供理论依据

Abstract

This paper sets up a multifield coupling simulation model based on Modelica modeling language and a unified multi-domain modeling and simulation platform named MWorks. The typical operation condition of hoisting from ground suddenly is simulated dynamically with computer. The dynamic characteristics of hydraulic and mechanical parts of the hoisting mechanism are analyzed. Also the effect of the Pump-controlled system is studied. It is shown that mathematical model will properly simulate the hoisting mechanism performance, show the effect of hydraulic coupling and the result of this study provides a theoretical basis for the design of the hydraulic hoisting mechanism for truck and crawler cranes.
