In this study, we theoretically investigated Methyl hydrazinecarbodithioate by quantum chemical calculations for geometry optimization, vibration frequencies, and electronic structure parameters. The geometry optimization by DFT, ab initio MP2 method and the frequency calculation by DFT method was performed at the highest available Pople style 6-311G++(3df,3pd) basis set level. The semi-emp...

In the current work, different methods for optimization of turbine blade internal cooling are investigated, to achieve higher cyclic efficiency and output power for a typical gas turbine. A simple two-dimensional model of C3X blade is simulated and validated with available experimental data. The optimization process is performed on this model with two different methods. The first method is ...

In this paper, the structural optimization of high-rise guyed tower is carried out for wire and column schemes. The schemes are compared from four wires eight wires, width column, uniform cross-section variable etc. And single-column with recommended tower. Through full-scale test study tower, safety feasibility engineering application verified. According to technical economic analysis traditio...

Abstract To meet the requirements of large tolerance, high precision, soft capture and reliability space gripper, a three finger end effector is developed. The gripper adopts fingered configuration, which needs to be used together with corresponding adapter. It characterized by stable grip, clamping force, tolerance strong correction ability. A 6-DOF microgravity equivalent device innovatively ...
