Investigation of cutting performance of a circular saw blade based on ANSYS/LS-DYNA
Zhiwen Wang, Qingliang Zeng, Zhenguo Lu, Lirong Wan, Xin Zhang, Zhihai Liu
Izvirni znanstveni članek
Oznake: circular saw blades;rock damage;cutting forces;stress;
The circular saw blade is widely applied in rock processing; its cutting performance significantly impacts rock processing. Therefore, the numerical simulation model of rock cutting with the flexible circular saw blade has been established to investigate the effects of cutting parameters on the stre ...

Investigation of dynamic behaviour of four-leg hydraulic support under double-impact load
Yunyue Xie, Qingliang Zeng, Kao Jiang, Zhaosheng Meng, Qinghai Li, Junming Zhang
Izvirni znanstveni članek
Oznake: impact load;four-leg hydraulic support;double-impact;force transmission;numerical simulation;
Hydraulic support is the key support equipment for underground coal mining. The frequent impact load during the mining process easily causes damage to the hinge joints and reduces the stability of the hydraulic support. To improve the stability of the hydraulic support, a rigid-flexible coupling num ...

Study on the dynamic characteristics of bit anchor cable drilling in the gravel sediments of a soft rock bottom hole
Kuidong Gao, Jihai Liu, Qingliang Zeng, Jingyi Cheng, Liqing Sun, Lisong Lin
Izvirni znanstveni članek
Oznake: bit;anchor cable;gravel drilling;dynamic characteristic;
During the pore-forming stage of floor heave treatment, the phenomenon of gravel sediment accumulation in the bottom hole often occurs, which causes great difficulties in the normal installation of the anchor cable. Based on this observation, a new anchor cable installation method was proposed, whic ...
