【摘要】 简单介绍了利用铁木辛柯梁模拟钢板弹簧的基本理论,使用MSC Adams/Car软件建立了不考虑片间摩擦作用的钢板弹簧参数化模型。进行平行轮跳试验仿真。将所建立的钢板弹簧悬架系统应用于某商用车整车模型,进行平顺性仿真分析,并利用道路试验验证了钢板弹簧模型的正确性。通过修改关键参数迅速重新构建钢板弹簧模型,以改善整车平顺性,为改进钢板弹簧设计方案提供了依据。更多还原

【Abstract】 The common theory of building leaf-spring model with beam method is introduced simply.The leaf-spring model with various stiffness values is built by using MSC Adams/Car without considering the friction between the leaves.The simulation of parallel wheel travel is carried out.The full vehicle multi-body dynamics model is created in Adams/Car.The simulation of ride performance is carried out,and its results are conformable to that of vehicle test on proving ground.Therefore,it proves that virtual prototype model is correct and believable.The stiffness value used in the simulation of ride performance can be got through adjusting the key parameters of the beam,the analysis can provide evidence in designing leaf-spring.更多还原
