Abstract：To excavate rationally technical potential, design and application of freight bogies need to rely on the basic test means so as to gradually form the correct cognition of their suspension nonlinearity through heuristic model simulations, and avoid correlative excitations to be produced between lightweight car-body and running part.With the rigid-flexible coupled simulation technique, the analyses of typical engineering cases indicated that the clamping stagnation in laden is one of the main causes to form correlative excitations; under influences of the clamping stagnation in laden, the local structural instability in inclined bars of central lateral trestles and lateral structural instability of central side-walls appear, both of them are converted into vibration cracking or vibration fatigue problem; the equivalent wedge friction model has heuristic significances to affect dry friction nonlinearity, and form two correct cognitions including that relative friction factor is not constant, it is generally less than 0.10 in laden and that the unilateral mechanical property of clamping stagnation makes vertical dynamic loads of central bowls tend to pulse-type ones and its negative effects on fatigue damage of lightweight car-body structure can’t be ignored; combined with demands of rapid railway freight, the technical scheme to solve problems of clamping stagnation in laden is reasonably formulated, i.e., the strong nonlinear influences of dry friction can be removed or reduced through adopting the novel technique of composite wedge, referencing typical configurations and increasing the wedge angle appropriately.
