通过对液压支架双耳联接头恶劣工况受力状态的分析,得出双耳联接头常见损坏部位与损坏原因,针对双耳联接头的受力特点与损坏原因对双耳联接头的结构进行优化设计,同时采用数值模拟方法对优化设计前后的联接头进行受力分析,通过对比应力云图得出优化设计后的双耳联接头受力状态较好,最后指出在双耳联接头设计中的注意事项。 Based on the analysis of the stress state of the binaural joints of hydraulic support, the common damaged parts of the binaural joints and the causes of the damage were obtained. The structure of the binaural joints was analyzed according to the stress characteristics and the causes of the damage of the binaural joints Optimize the design, at the same time using numerical simulation method to optimize the design of the joint before and after the force analysis by comparing the stress cloud chart shows that the optimal design of the double-ear coupling is better stress state, and finally pointed out in the design of the double-ear coupling Precautions.
