Design of the Main Parameter of Large and Heavy Workpieces Upender for Shell Units of Nuclear Power and Hydrogenation Equipment

Abstract:

In the production process for large and heavy workpieces of Nuclear Islande equipment and Hydrogenation reactor, Turn is the important technics of the convergence of every technological process, and a direct impact on production efficiency and production safety and production quality. The researching and manufacturing of overloaded upender for large and heavy workpieces will effectively contribute to the improvement of the production capacity. The force model under maximum load conditions is established. The force of upender body in the eversion process is analyzed. The main drive torque formula for upender turnover is obtained. From the actual functioning of the overloaded upender for large and heavy workpieces, carring a maximum load, the upender flip process is dynamic simulation on ADAMS. After the results were compared with theoretical calculations showed that: the variation between the two is consistent. The main parameter for driving of upender is designed. By theoretical calculations confirming simulation with each other, in simulation model, the feasibility of using the contact vice for defining non-hinged rotation vice is verified. And a new solution is provided for adding non-hinged rotation vice constraints to a similar shstem dynamics model. In this paper work it has an engineering value for the design of large and heavy equipment.
