摘要: 针对传统起重机变幅系统仿真分析中未建立机械结构准确模型,不能精确模拟变幅动作过程的问题,以某大型起重机为例,在变幅机构的工作原理和简化数学模型分析基础上,基于NX和AMESim软件分别建立高精度三维机械结构和液压系统仿真分析模型;然后在NX的运动分析模块Simcenter 3D中建立机液联合接口,继而搭建机械-液压联合仿真分析系统,仿真计算了变幅上升过程中的变幅液压缸无杆腔压力和变幅角度等关键参数曲线,并进一步计算传统情况单独基于AMESim的仿真分析结果;通过将机液联合仿真与基于AMESim的仿真分析结果与试验测试结果对比可知,联合仿真分析的无杆腔压力和变幅角度等关键参数分布曲线更接近试验测试曲线,可大幅提高仿真分析精度,更准确模拟起重机的变幅动作过程。

Abstract: Aiming at the problem that the crane luffing process cannot be accurately simulated since the accurate mechanical structure model is not established in the traditional simulation analysis, firstly, based on the analysis of the working principle and simplified mathematical model of the luffing mechanism, the high-precision 3D mechanical structure and hydraulic system simulation analysis models are established respectively based on the software NX and AMESim;Then, the mechanical and hydraulic co-simulation system is built based on mechanical-hydraulic interface in Simcenter 3D(motion analysis module of NX). The key parameter curves such as rodless cavity pressure of the hydraulic cylinder and luffing angle in the luffing rise process are simulated and calculated, and the simulation analysis results based on AMESim in the traditional situation are further calculated;By comparing the results of mechanical and hydraulic co-simulation and simulation analysis based on AMESim with the test results, it can be seen that the distribution curves of key parameters such as rodless cavity pressure and luffing angle analyzed by co-simulation are closer to the test curves, which can greatly improve the simulation analysis accuracy and more accurately simulate the luffing action process of crane.

Key words: crane luffing system, mechanical and hydraulic coupling, co-simulation, 3D structure model, luffing angle
