摘要

打击气压是液压锤打击参量中影响动态特性的关键因素,为了提高设备的控制精度,以液气锤为研究对象,分别建立液气锤打击过程在未发生塑性变形阶段和塑性变形阶段的拉格朗日动力学模型,利用Matlab/Simulink数值计算方法研究液气锤打击过程的运动规律,深入分析打击气压变化对锻打系统动态特性的影响,为后期设备调试提供理论依据,以达到精确控制的目的。经现场试验研究表明,控制系统可以满足液气锤精确打击工艺的要求。

Abstract

Blow pressure is the key factor to influence the dynamic characteristics of liquid-air hammer,in order to improving control accuracy of the forging equipment,liquid-air hammer was regard as research object,established liquid-air hammer blow process stages of non-plastic deformation and plastic deformation of Lagrange dynamics model,using the Matlab/Simulink numerical simulation to analyze movement regularity of liquid-air hammer blow process,researched for blow pressure impact on the dynamic characteristics of liquid-air hammer,provided the theoretical basis for the equipment later debugging in order to achieve the purpose of precise control.The field experiment results show that the control system can meet the requirements of liquid-air hammer precision blow process.
