Because the complex configuration and variation of sections does not allow for sufficiently accurate theoretical calculations to determine the elastic strain, and it is necessary to perform experimental determination also. The paper experimentally determined elastic deformation of the framework and it’s calculated rigidity characteristic. Calculate the linear rigidity characteristic – on the direction of the force and angular rigiditys characteristic. Calculate also the mechanical work consumed for elastic deformation of the fight and then determines how much percent of mechanical work of the press.
