FIELD: measurement equipment.SUBSTANCE: loading impact at a sample of a product is applied with a load, which in its shape, weight and dynamics of impact corresponds to typical load at the product in process of its operation at typical time intervals of impact, and the index, values of which are assessed at the end of the impact, is relative deformation of product compression, which is determined on the basis of the ratio. The device comprises a test table, a load, a measurement scale, an indicator of load position variation, the first lever, at one end of which there is a load fixed, a reducer-multiplier fixed on the test table and kinematically connected with the indicator of load position variation, an axis connected by one end with the reducer, and by the other end - to the second end of the first lever, a frame fixed on the test table, the first and second cylinders, connected by a hydraulic line via a throttling valve, and the second lever, with one end hingedly connected to the test table, and in the middle part hingedly connected to the second cylinder, at the same time the first cylinder is hingedly connected by one end to the frame crosspiece, and by the second one - with the first lever in its middle part.EFFECT: expansion of a field of application and increased accuracy.2 cl, 1 dwg |
