Экспериментальное исследование контактного взаимодействия сложнопрофильных шероховатых тел с учетом податливости

Abstract

Important task is to determine the possible application of the developed, adapted or improved methods for the numerical investigation. Accuracy of numerical solutions by varying the parameters of numerical models is also an important task. The boundary element method is used for numerical solution of the contact problem. The article describes the method and results of experimental research of contact interaction complex-shaped bodies. The technology of pressure-sensitive films, which are placed between the contacting bodies, was used; they serve as indicators for the determination of the contact areas and sensors for measuring the contact pressure distribution. The correspondence used model with Winkler elastic foundation was shown. The magnitude of the compliance of the intermediate layer was obtained experimentally. Possibility of modeling contact interaction of complex-shaped bodies with the elastic layer using variants of the method of boundary integral equations has been demonstrated.
