The Influence of Friction Coefficient on Tenon/Groove Contact Performance in Nickel-based Turbine Blade-disc Guocai Zhou1,a, Zhixun Wen2,b Zhufeng Yue3,c and Yufen Gao4,d 1,2,3,4School of Astronautics, Northwestern Polytechnical University, Xi’an 710072, China 2,3,4School of Mechanics and Civil.& Architecture, Northwestern Polytechnical University, Xi’an 710129, China azguocai882@nwpu.edu.cn,bzxwen@nwpu.edu.cn,czfyue@nwpu.edu.cn, dyufengao@mail.nwpu.edu.cn Keywords: crystallographic orientation; friction coefficient; tenon/groove; contact stress; fatigue life Abstract.
Therefore, the research of contact fatigue in tenon/groove of turbine blade has great significant in theory and engineering applications.
They obtained some conclusions to fit the engineering applications, but a deeper research was needed.
In engineering applications, lubricating the contact surface, increasing the surface coating or other chemical methods can be used to decrease friction coefficient.

New technology and mechanism study of the bearing enhancement of broken rock zone in underground rock roadway Pengwei Hao1,2,a, Hailong Dong2,b, Zhaohui Liu1,c, Jingpei Li1,d, Laiwang Jing2,e 1 School of Civil Engineering and Mechanics, China University of Mining and Technology (Beijing), Beijing, China, 10083 2 College of Science, Anhui University of Science and Technology, Huainan, Anhui, China, 232001 a57066490@qq.com, b824426446@qq.com, clzh4969183@163.com, dLijp6666@126.com, elxybg@aust.edu.cn Key words: broken rock zone, bolt support, floor heave, equivalent stress Abstract: Treating surrounding rock as absolutely loose mass helps to determine positions of the four “key reinforced points” in roadway, in other words, they are juncture locations between 45 degrees angle directions of two arch haunches and two footwalls.
Stability of roadway surrounding rock is similar to human body in some places, reinforcement for one position will have big or small impacts on other positions, so it is necessary to treat surrounding rock support as a systems engineering, never “to doctor the head if be headache, to doctor the foot if be foot-ache”. 3 Significances of key reinforced points Finding out key reinforced points accurately, can not only control deformation of surrounding rock effectively, but also can save lots of supporting materials.
