FIELD: physics. ^ SUBSTANCE: installation for testing articles on effect of impact pulses has a base fitted with apparatus for the tested article, a group of hammers in form of loads, elastic members joined to the hammers, separate controlled trigger devices for the hammers and apparatus for accelerating the hammers, which includes a shaft and a shaft rotary drive. The installation has flexible rods which are joined by one end to the hammers. There are wheels on the shaft of the acceleration apparatus, on which second ends of the flexible rods are wound. The trigger devices are in form of holders for joining the wheels with the shaft and the elastic members are tied to the base. ^ EFFECT: increased amount of information by carrying out tests with multipoint impact loading of the surface of articles with independent variation of frequency and impact force during tests. ^ 1 dwg |
