【摘要】:双滚刀岩石试验台可以进行刀间距、贯入度等参数对滚刀破岩效率影响的试验,为掘进机刀盘滚刀的布置提供设计依据。设计了可调整刀间距的高速双滚刀岩石综合试验台并进行了受力和模态的有限元分析,并利用试验台对普通花岗岩进行了滚压试验。结果表明:经有限元分析试验台的应力小于制造材料的许用应力,分析了试验台振型及振动频率和振幅;岩石滚压试验表明试验台在强度和振动方面满足使用要求;通过普通花岗岩的破岩试验测得破岩力及支撑框架振动幅值,所设计的试验台滚压花岗岩具有良好的使用效果,满足工程研究及使用。
[Abstract]:The influence of the parameters such as tool spacing and penetration on the rock breaking efficiency of the hob can be tested on the double hob rock test bench, which provides the design basis for the arrangement of the cutter head hob of the tunneling machine. A high speed double hob rock comprehensive test-bed with adjustable tool spacing was designed, and the finite element analysis of force and mode was carried out, and the rolling test of ordinary granite was carried out by using the test bed. The results show that the stress of the test bed is smaller than the allowable stress of the manufacturing material, the vibration frequency and amplitude of the test bed are analyzed, and the rock rolling test shows that the test bed meets the requirements of strength and vibration. The rock breaking force and vibration amplitude of bracing frame are measured by rock breaking test of ordinary granite. The rolling granite of the designed test bed has good application effect, which is suitable for engineering research and application.
