Abstract
The This article deals with the replacement of the magnetic grippers on the VPO-3-3000 machines with roller grippers. The novelty lies in the establishment of dependences characterizing stress and strain in the elements of the lifting and straightening devices and in the rails during the operation. Reliability of the program for calculating the structural parameters of the lifting and straightening device for the VPO-3-3000 track renewal machine is shown. The developed design of the lifting and straightening device makes it possible to select the rational parameters of the technology and the operating mode of the device. It This design is recommended to for use it when developing working bodies for the straightening machines. The article presents the calculation of the lifting and straightening device structural elements' strength during its operation, in the Ansys WB software package.
