摘　　要：建立了折弯机的三维模型,分析了下横梁液压补偿机构的原理并对其进行了设计计算。采用有限元软件CosmosWorks对折弯机下横梁进行了静力分析,定量地描述了下横梁的变形和应力分布状态。通过折弯角度的误差分析以及折弯机滑块与下横梁上表面的挠度曲线的对比研究,得到液压补偿装置的变形规律,验证了液压补偿系统具备对下横梁的挠曲变形进行补偿的能力,为液压补偿装置的设计和使用提供了理论依据。A three-dimensional model of press brake has been established. The principle of lower beam hydraulic compensation mechanism has been analyzed and designed. The finite element software CosmosWorks has been used to conduct the static analysis of lower beam on press brake. The deformation and stress distribution of lower beam have been quantitatively described. The deformation rules of hydraulic compensation device have been obtained by error analysis of the folding angle and comparative study on flexibility curves of press brake slider and upper surface of lower beam. It is verified that the hydraulic compensation system is capable of compensating for the lower beam,which provides theoretical reference for design and application of the hydraulic compensation mechanism.
