RAIL STAND FOR SIMULATION OF IMPACT IMPACTS

摘要

A useful model "The rail stand for modeling of impacts" can be used for dynamic testing facilities on impact. The purpose of this utility model is to provide a stand structure for percussion dynamic test products on exposure to shock pulses with predetermined shapes and parameters, including high-energy, with simultaneous high-speed full-scale simulation test and the effect on it of the incident aerodynamic flow. This object is achieved in that on the carriage with the test object being accelerated rocket motors on rails missile track cantilevered cutter, the cutting edge in the direction of carriage movement, and along the rails installed abutment with a set of rods arranged in the tool path transversely with respect to its a cutting edge direction. Sectional profile, size, material, number of rods, their location on the palm, and the sharpening angle and cutter orientation of its cutting edge in a plane cutting the rods are assigned in accordance with predetermined parameters and shape of the shock pulse. The impactor momentum realized when the carriage movement with the test object during interaction with the cutter rod material.
