Pneumatic test bench for strength testing under the action of vertical loads

摘要

The utility model refers to the testing technique, in particular to the impact test equipment, which is characteristic for the transport of various instruments and equipment. The pneumatic bench contains a support base with a means of acting on the movable platform for fixing the object under test, guides that are rigidly connected to the support base, a lower damper located between the movable platform and the means of acting on it. As a means of action, the bench is equipped with a controlled double-acting pneumatic cylinder, which provides movement of the movable platform along the cylindrical guides by means of a rod connected to the mobile platform. Linear bearings fitted with flanges for fastening to a movable platform are mounted on the cylindrical guides. The stand additionally contains a pneumatic cylinder control unit, upper dampers of a given stiffness placed on the cylindrical rails above the movable platform, limiting the movement of the movable platform. The technical result: obtaining specified positive and negative shock loads for one work cycle of the stand, work of the stand in automatic mode, shortening the test time, more accurate reproduction of the impact load. 2 z.p. f-ly, 1 il. more accurate reproduction of the shock load. 2 z.p. f-ly, 1 il. more accurate reproduction of the shock load. 2 z.p. f-ly, 1 il.
