Abstract:

Based on the methods of CAE,bench testing and vehicle torsion test,the torsional mechanism of vehicle was revealed through using the normal condition.The research promotes the precision of the simulation value of the body torsional rigidity and the testing value by using the theory of non-linear interpolating,and the torsional stiffness of body and the torsional stiffness of suspension were systematically analyzed,and the theoretical basis and test methods for the static torsional stiffness of whole vehicle were provided,namely,the torsional stiffness of the equipped state body is 1.72 times than BIW,the proportion of the front suspension torsional stiffness and rear suspension is 1.44,the torsional stiffness of BIW is 5.8 times than suspension,the torsional stiffness of the equipped state body is 11 times than the suspension,ande the torsional stiffness of the equipped state body is 1.89 times than BIW.On the basis of the theory study,three matching principles are explored.It provides theoretical basis and design methods for the passenger car.The research results have the promotional value of practicability and a wide range of engineering application.

Key words: vehicle engineering, body, torsional stiffness of suspension, torsional stiffness, distribution
