The article provides a review of models allowing to take into account the viscoelastic properties of springs made using polymer composite materials. The features of solving equations with fractional derivatives that describe the considered models are considered. The equation of the stress-strain state of the composite spring is obtained, which takes into account the rheological properties of the material. A model has been developed in MATLAB / Simulink, which allows calculating composite springs. A composite spring was made and tested, which made it possible to compare the elastic characteristics of the spring obtained as a result of modeling and experiment. The authors of the article determined the scope of such springs in the automotive industry and the direction of improvement of composite springs used in wheeled vehicles.
