| Abstract: | Based on space analytic geometry,a mathematic model for double wishbone torsion bar suspension with steered wheel and 3D spatial structure is built,taking into consideration the spatial structure and its gesture and dimension of guiding linkages,elastic elements and damping elements.The characteristics of nonlinear damping and stiffness of spatial structure in the suspension are studied.The results of anlysis show that the equivalent damping and stiffness of the suspension exhibit obvious nonlinear features... |
