<p>The invention belongs to the field of testing machinery and can be used in strength tests of constructions and for simulation of construction motions. In addition, the invention can be used in production processes for shaping panels and bars and for making sophisticated-shape parts of flat and straight-line blanks. The specific features of the construction loading, deformation, and movement method being advanced are as follows: (a) As soon as a certain travel length that is close to the maximum permissible value for a particular drive is over, the load is passed to the second drive while the first drive returns to the initial position. (b) When the load is being passed from one drive to the other, the sum of the loads applied to the first and second drives remains equal to the program-controlled value. The method advanced provides a considerable expansion of the construction movement range, a unification of the long movement drives, and an increase of the loading accuracy. <IMAGE></p> |
