Performance Analysis of On-line Cleaning Machine for Rail Transit Vehicle Skin

To verify whether a certain type of independent research and development of rail transit online cleaning machine to meet the performance requirements. First of all, building washer assembly finite element model, conducting modal analysis of the washer assembly based on OptiStruct, Verify whether the connection of each part of the structure meets the requirements under the incentive. Then, by applying impact loads under three different operating conditions to verify whether the static strength requirements are met. The analysis results show that the safety factors under all three conditions are all greater than 1.3, meeting the static strength design requirements.
