Design of the Mechanical Device of the Manipulator Design Principle.
According to the cylindrical supporting bar under the stress of 175.4N, the displacement constraint, material property, and stress, etc[4]. of the cylindrical supporting bar are set with Pro/E, the static analysis of the cylindrical supporting bar is newly conducted, and the analysis result is finally obtained from the result definition window.
The correction factor is selected to be k=1.1 and the pressure here is calculated to be F=(6/0.319/1.1)N=17.09N with the influence of the frictional force of influence.
What's more, the accuracy of spare parts processed according to related drawings meets requirements, the assembly accuracy of the shearing mechanism may affect the performance to some extent, and the its stability shall be yet to be improved.

The wearings on beads in two modes of vertical and horizontal cuttings are evaluated separetely and modelled as function of rock properties, machine and cutting characteristics.
For this purpose, the rocks of different mechanical properties in the field are cut horizontally and vertically by using the diamond wire cutting machines.
The physical and mechanical properties of the rock are determined in laboratory under ISRM [8] and T.S.E.
According to Table 4, the rock parameters namely the modulus of elasticity and specific gravity and the machine parameters namely the cutting time and energy and water consumption are the most important parameters affecting the bead wearing.
This methodology gives the comparative effects of the factors on wearing.

It is well known that nanocrystalline materials have enhanced diffusion properties due to their high grain boundary density which act as fast diffusion channels compared to the lattice.
Introduction In the past fifteen years, nanocrystalline materials developed by severe plastic deformation are of great interest since they show enhanced mechanical properties [1] [2] [3] and especially they show enhanced diffusion properties which allow thermochemical treatments like nitriding to be more efficient on such materials [4].
Many studies have shown that mechanical properties of the nitrided nanocrystalline materials are much enhanced compared to their coarse grain equivalent [4] [5] [6] [7] [8].
Thus, for given mechanical properties after treatment, they present deeper affected depths [4], lower treatment temperatures [4], or reduced nitriding duration [9].

Therefore, the design of power-train vibration isolation system directly affects the NVH performance.
In general, one definite power-train’s physical parameter will not change easily, so we can only optimize the physical parameter of mounting component geometry and physical properties [6].
