Abstract: Reliability optimization design of the gear box is proposed. It includes an objective function, 30 design variables and 52 constraints. It is important to note that material properties, geometry parameters and applied loads of the structure are assumed to be normal random variables. Reliability calculation adopts the HL-RF method. The comparison of design parameters demonstrates the proposed method.

Abstract: The end coupling is the main component of the aluminum hot rolling process. The end coupling used for transmission of rotational power with heavy-duty load. Fracture of the end coupling causes serious economic injury because an end coupling is a very expensive component and takes a long time to repair. To prevent the destruction of the end coupling it is essential for mechanical life cycle to be known. In this paper, a parameter study on end coupling was performed in order to minimize maximum stress of an end coupling under static loads. To verify the interference of spindle assembly with modified end coupling, kinematic simulation was performed by applying the various combination type and dynamic boundary condition of the spindle assembly. The interference of an optimized model did not occur during combination process and driving process. As a result of an optimum design for life extension on end coupling, the maximum stress of end coupling was reduced about 26% compared with original model.

Abstract: Cryostat is an important equipment of International Thermonuclear Experimental Reactor (ITER).It is the outer part of ITER Tokamak. There are three issues to solve the parametric design of cryostat: First, the parametric description of cryostat model; Second, program design; Third, the establishment of Database. In this paper, take a simplified model of the cryostat as an example, after the parametric description of cryostat finished, the parametric design of cryostat has realized through ACCESS Database and the automation technology of the secondary development of CATIA under VB (Visual Basic).

Abstract: For being convenient for researching the dynamic characteristic and the improvement and use of the planar six bar mechanism, for improving the dynamic technical performance, the three-dimensional solid model of the mechanism was established with ADAMS. Each part of the model in ADAMS was set up. Simulation analysis on the working process of the mechanism was achieved. The structure optimization parameters of the mechanism were obtained. The result proves that the vertical location of revolute joint of link and rocker, the location of revolute joint of crank and frame, the horizontal locations of two revolute joints of link are almost no impact on the vertical speed of slider. The vertical locations of revolute joint of frame and rocker and revolute joint of block and slider have less impact on the vertical speed and acceleration of slider. The vertical location of revolute joint of link and crank, the horizontal locations of revolute joint of frame and rocker and revolute joint of block and slider have greater impact on the maximum vertical speed and acceleration of slider.
