Prediction model in correcting distortion for elevator guide rail base on FEM method

As the elevator´s guidance system, the elevator guide rail is an important component affecting the safety and comfortableness of elevator. Its distortion degree is an important factor to restricting the development of express elevator. FEM software ABAQUS is used to analyze the correcting method for six initial distortion degree rail in this thesis, the plan of dividing into different steps is put foreword, numerical simulation of correcting stroke parameter for every distortion degree is finished, and obtain satisfactory results, then get the T guide rail´s correcting stroke prediction model based on the parameter.
