摘要
为了缓解主轴的疲劳破坏程度,提高露天矿环锤式破碎机主轴寿命,以PCH1010 环锤式破碎机为研究对象,基于ADAMS对破碎过程进行动力学仿真,得到关键零部件的受力数据;结合名义应力法和疲劳累计损伤原理对环锤式破碎机主轴进行疲劳寿命计算,在保证夹板和圆盘结构强度的前提下,对圆盘和夹板的结构进行优化设计,并根据优化结果对环锤式破碎机主轴总成进行重建.结果表明:重建后的环锤式破碎机主轴最小循环次数为 5.6×109 次,疲劳寿命提高了 60%,主轴总成在运行稳定性方面有明显的改善.
Abstract
In order to alleviate the fatigue damage of the main shaft and improve the life of the main shaft of the ring hammer crusher in the open-pit mine,this article takes the PCH1010 ring hammer crusher as the research object,carries out the dynamic simulation of the crushing process based on ADAMS,obtains the force data of the key parts.Based on the nominal stress method and the principle of fatigue cumulative damage,the article calculates fatigue life of the main shaft of the ring hammer crusher.Under the premise of ensuring the structural strength of the splint and the disc,the aticle optimizes and designs the structure of the disc and the splint,and reconstructes the main shaft assembly of the ring hammer crusher according to the optimization results.The results indicate that the minimum number of cycles of the reconstructed ring hammer crusher spindle is 5.6×109 times,the fatigue life is increased by 60%,and the spindle assembly is significantly improved in terms of operational stability.
