| 摘 要： | 为了研究星轮转速对连续采煤机和掘进机装载机构效率的影响,采用有限元分析软件ANSYS,对星轮装载机构进行了模态分析和谐响应分析,分别得出了星轮机构前10阶固有频率及位移与频率的关系曲线,确定星轮机构不发生共振的激振频率在1.8～2.6 Hz,星轮机构工作的安全转速在36～52 r/min.该研究为改进星轮的设计和改善星轮的性能提供理论依据.

| Abstract: | Targeted at the study of the effect of star-wheel rotational speed on loading mechanism of continuous miner and roadheader,the paper offers modal analysis and harmonic response analysis of a star-wheel loading mechanism by means of finite element analysis software ANSYS.The analysis finds relational curves between fro-10 nature frequencies,displacement and frequency and determines the excitation frequency of 1.8~2.6 Hz in which star-wheel loading mechanism is subjected to no resonance,and safe rotation spee... |
