STAND FOR WHEELS AND WHEEL PAIR AXLES DURABILITY TESTING AND METHOD OF TESTING

摘要

FIELD: test equipment.;SUBSTANCE: invention relates to stands for wheels and axles of wheel pairs of railway rolling stock durability testing. Stand contains a motor, loader with a free mass, support plate supported by springs on the foundation. On the support plate, two or more cavities for installing and fixation of the objects under test are equipped evenly with respect to its center, equipped with load devices with free masses, with the possibility of rotation them with the same rotational speed by means of a gear transmission while maintaining such a mutual arrangement of the free masses, at which the inertia forces created by them maximally balance each other within the support plate. Gist: in the nests made on the support plate, two or more test objects are installed and fixed, on the upper non-fixed ends of the axes of which load devices with free masses are installed, which are driven into rotation with identical rotational speed, and free masses are selected so that, to ensure a given amplitude of voltage changes in the objects under test, and orient each other in such a way that the main vector and the main moment of inertia created by them are minimal and do not cause significant vibration of the support plate.;EFFECT: possibility of simultaneous testing on one support plate of two or more objects with the maximum balancing of inertia forces transferred to it.;5 cl, 4 dwg
