Axles with leaf spring suspension systems are still a popular choice in many commercial vehicles. However, leaf springs are not in perfect conformity to standard multibody vehicle models because they combine guidance and suspension in one single element. Combining standard multibody vehicle models with sophisticated finite element leaf spring models results in rather complex and computing time-consuming solutions. Purely kinematic models, defined by lookup tables or the design kinematics approach, cover only some but not all features of the leaf spring suspension. As shown here, the five-link model, which incorporates a quasi-static solution of the leaf spring compliance, provides a very practical model. It is comparatively lean and provides results of sufficient accuracy in the whole application range.

带有板簧悬挂系统的车轴仍然是许多商用车的热门选择。然而，板簧并不完全符合标准的多体车辆模型，因为它们将引导和悬架结合在一个元件中。将标准多体车辆模型与复杂的有限元板簧模型相结合会产生相当复杂且计算耗时的解决方案。由查找表或设计运动学方法定义的纯运动学模型仅涵盖了板簧悬架的一些但并非全部特征。如此处所示，五连杆模型结合了板簧柔度的准静态解，提供了一个非常实用的模型。它相对精简，并在整个应用范围内提供足够准确的结果。
