Abstract

The attitude displacement process of nuclear power large piecesis time-consuming and very dangerous, which has became one of the important factors for improving productivity and enhancing the workpiece's surface quality.However, the research and development of upenders for nuclear power large parts is seldom reported no matter in domestic or abroad. The method that crown with wire ropeis commonly used , which is very low controllability. It carries out the research based on a nuclear large pieces 180° upender which we jointly developed with a heavy machinery factory. With the application of theoretical analysis and simulation analysis, the complex stressstate of dangerous sport nodes and the turning process in the equipment's operation process that upender completes the most difficult and most dangerous 300 tons dome head 180-degree shift is analyzed. The study result ensures the safety and reliability of the equipment for trial operation. It provides reliable theoretical for equipment structure optimization, dynamic parameter selection. There search also plays an important reference role for making turning process of different kinds of nuclear power large pieces.
