The rigid subframe cannot fully reflect the impact of its own elastic deformation on the movement of the car.Hypermesh was used to flex the front subframe and generate a rigid-flex coupling vehicle model.The linear simulation of the vehicle model was carried out using the Belgian road spectrum,and the lateral,lateral and vertical accelerations at the centroid of the rigid-flexible coupling vehicle were obtained,and compared with the simulation data of the vehicle equipped with a rigid front subframe.The results show that the acceleration at the center of mass of the rigid-flexible coupling vehicle is smaller,which can reflect the influence of the elastic deformation of the frame of the flexible front sub-vehicle on the motion of the vehicle to a greater extent.
