ABSTRACT
On the background of a bridge, the existing maintenance vehicle has problems such as a small operation area, small load, and expensive price. A new type of maintenance vehicle suitable for the bridge is developed. In order to verify its deformation and carrying capacity, the mechanical performance of the maintenance vehicle door frame is simulated and analyzed by the finite element software ANSYS. Then, the mechanical performance and stability of the maintenance vehicle truss under two working conditions are analyzed by MIDAS simulation and through various combinations of live load and wind load, it may be encountered in real working environments. Simulation results show that the maintenance vehicle's size and performance can meet the requirement of practical engineering, strength, and rigidity.
