The Simulation and Test of Anti-Torsion Frame for Off-Road Vehicle
This paper studied the calculation and design of anti-torsion vehicle frame to reduce the torque transmission via the frame and advance the reliability of off-road vehicle’s loading equipment. Two kinds of projects are designed and analyzed by the tools of FEA on the extreme condition, then tested the prototypes of the two projects to compare the distributing of the load equipment’s stress and analyzed the road reliability of the whole system to validate the feasibility of the projects. The test data indicates that the average principal stress decreased to 43.6% ~49.2% after equipped flexible vehicle frame. This paper gives a helpful trial for decreasing the stress transmission from the ground to the vehicles on the off-road terrains and improving the reliability of the special’s load equipment.
