Study on Failure Trend of Double Column Deflection Machine Structure on Basis of Static Strength Analysis

To ensure the safe use of double column deflection machine for processing and manufacturing railway vehicles. This paper analyzes the use conditions of double column deflection machine, and makes a contact nonlinear finite element analysis on various typical use conditions. The positions of parts subject to danger can be found out through the results of static strength analysis, which finds out the weaknesses and prejudges the failure trend of parts, and which provides guidance for prejudging the faults in actual production and can prevent occurrence of accidents.
