The reduction in the duration of the development of new vehicles and the associated desire to re-duce the costs of automotive plants contribute to a more active application of mathematical model-ing to solve engineering problems. The tasks, which are analyzing and predicting the fatigue life of vehicle components and assemblies, can be solved using a set of methods and tools of mathematical modeling. This article discusses the development of a complex of mathematical models of the front and rear suspensions of a passenger automobile, which have the properties necessary for accurate reproduc-tion of wheel loads and dynamic behavior of the suspension as a mechanical system. The complex of mathematical models is implemented in a multi-link modeling environment. The models are de-signed to carry out a subsequent validation study of the loading of individual suspension compo-nents during forced service life tests. In the future, this complex of mathematical models can be used for simulation of semi-natural forced resource tests of the suspension module, as well as a sample for the development of suspension models of other automobiles. The purpose of this work is to form sufficient requirements for mathematical models for the im-plementation of fatigue durability studies using mathematical modeling methods and obtaining reli-able calculation results. Research engineers will be able to follow these requirements to determine and collect initial data for the development of their own mathematical models.
