二维颗粒堆力传递模型在颚式破碎机设计分析集成系统中的应用

为缩短颚式破碎机的设计周期和满足智能化生产对颚式破碎机不同应用场合的要求,根据颚式破碎机的机构特点,开发了基于SolidWorks和ANSYS联合二次开发的颚式破碎机设计分析集成系统。应用圣维南原理建立了二维颗粒堆力传递模型,以确定不同破碎颗粒大小下颚板应力分布情况。对颚板进行静力学分析,并运用APDL进行参数化建模优化设计。结果表明,该模型可有效提高颚式破碎机设计分析集成系统对不同破碎颗粒的适应性,大大提高颚式破碎机设计准确度和效率。

Application of Two-dimensional Particle Packs Force Transfer Model in Jaw Crusher Design and Analysis Integrated System

In order to shorten the design cycle of jaw crusher and meet the requirements of intelligent production for different application occasions of jaw crusher,according to the mechanism characteristics of jaw crusher,an integrated system of design and analysis for jaw crusher was developed based on the secondary joint development of SolidWorks and ANSYS.Based on Saint Venant’s principle,a twodimensional particle pile force transfer model was established to determine the stress distribution of jaw plate with different particle sizes.The jaw plate statics were analyzed,and the parametric modeling optimization design was carried out by using APDL.The results show that the model can effectively improve the adaptability of the jaw crusher design and analysis integrated system to different crushed particles,greatly improve the design accuracy and efficiency of the jaw crusher.
