COMPUTATIONAL-EXPERIMENTAL ANALYSIS OF CONTACT INTERACTION BETWEEN TECHNOLOGICAL SYSTEMS PARTS

In the work on the example of parts of dividing dies the calculation-experimental analysis of contact interaction of elements of technological systems is carried out. For this purpose, parametric models of the system of contacting bodies are constructed. Numerical and experimental studies of the stress-strain state and contact interaction of the studied objects were performed in parallel. This makes it possible to establish the features of the distribution of the components of the stress-strain state and the contact pressure in the connection of bodies. The obtained experimental results are the basis for determining the parameters of finite-element models by the criterion of accuracy of numerical modeling of contact interaction of elements of technological systems.
