液压劈裂机楔块组件的有限元模拟

Finite Element Simulation on Wedge of Hydraulic Stone Splitter

液压劈裂器是液压劈裂机的关键部件,使用寿命如何直接影响到劈裂的效果和加工成本,从劈裂器的受力分析入手,应用ANSYS软件对内、外楔块进行了劈裂器各部分的应力分布分析,分别得出了内楔块和外楔块各部位的应力、变形值,其中外楔块的最大应力及变形值均发生在危险点的位置,并以此作为液压劈裂机提高楔块组件的性能提供了设计依据。

SpiRting wedge is the key part of hydraulic stone splitter. Operating life of the splitting wedge has a very important impact on final cost and effectiveness of the hydraulic stone splitter. A stress analyse was made to splitting wedge with software ANSYS.Through stress analyse on outer wedge and inside wedge, stresses and deformings on every part of them were got, where the bigest stress and deformation occurs at the dangerous point. The research provides a good basis for design of parts of hydraulic stone splitter.
