Abstract

The invention discloses a high-speed motion measuring instrument calibrating device capable of conveniently and accurately calibrating and measuring a conventional high-speed motion measuring device. The device comprises a worktable of which the upper surface is a smooth horizontal plane; two sides of the upper surface are provided with a bearing respectively; a permanent alnico thrust bar is horizontally arranged between the two bearings; the permanent alnico thrust bar is sleeved with a linear motor rotor; the lower end of the linear motor rotor is provided with an air floatation bearing which forms non-contact type supporting with the upper surface of the worktable; the device also comprises a metal strip raster measuring system, wherein a metal strip raster read head is arranged on the lower end face of the linear motor rotor; a metal strip raster is arranged on the upper surface of the worktable and corresponds to the metal strip raster read head; the device also comprises a microcomputer control system which is connected with the metal strip raster measuring system and the linear motor rotor respectively and can read a measuring result of the metal strip raster measuring system and control the motion of the linear motor rotor.

Description

technical field [0001] The invention relates to a calibration device for a high-speed motion measuring instrument, which uses magnetic levitation technology, can reproduce dynamic displacement, velocity, acceleration and other dynamic values ​​of high-speed motion, and can realize dynamic calibration of a high-speed motion measuring analyzer. Background technique [0002] In the field of military industry, high-speed motion measuring instruments, laser velocimeters, high-speed cameras, etc. are used to measure recoil parameters, such as displacement, velocity, and acceleration, for light weapons, small-caliber artillery and other weapons and equipment. Wait. Due to the lack of corresponding high-speed motion calibration devices to reproduce dynamic quantities, most measuring equipment has been in a state of being unable to calibrate for a long time. Currently, it is limited to vibration measurement standards to reproduce low speed and acceleration parameters below 0.5m / s, wh...
