| Abstract: | Using the method of finite element analysis and actual measurement,the load-carrying capacities of the prestressed stand on straightening machines are analyzed respectively under the situation of pretightening and straightening,and the evolution of prestressed stand stress is discussed.The result shows that the main reason of device failure is the impact stress during the process of steel biting and throwing.This study has the guiding meaning to the design of the frame of pre-tensioned leveler and the regul... |
