24-29Results of mathematical modeling of determination of character and the law of change of forces and tension arising in the field of contact of interacting bodies on the example of dynamic contact at impact of an elastic sphere about motionless, absolutely rigid plate are presented in article, at its flat movement. The received results can be used at calculations of contact forces and material tension in a metalwork at shock influences.
88-101The traffic speed increasing on the railways makes strict requirements to the supporting and supporting structures of the contact network, as well as to the parameters and indicators of the contact suspension. The presence of dry friction in the cantilever attachment points indicates a negative effect on the accuracy of adjusting the wires of the contact suspension and on its parameters. The article presents the results of studies of the dry friction value in the console fastening points depending on the type of the contact suspension and suggests a method for reducing friction in the console attachment points. The results of calculations of the effect of friction in the console attachment points on the tension variation along the length of the anchor section are presented.
