Damping slide block device for high-speed rocket sled test

Abstract

The invention discloses a damping slide block device for high-speed rocket sled test. The damping slide block device comprises a slide block body and a damping mechanism. The slide block body comprises a box-type cavity, the center of the box type cavity is provided with a positioning boss, and the sidewalls of the box-type cavity are provided with lateral connection holes. The damping mechanism is mounted in the box-type cavity, and comprises a casing, a vertical damping assembly, a course damping pad and a lateral damping pad, the center of the casing is provided with a positioning hole, the sidewalls of the casing are provided with kidney-shaped connecting holes, the casing is vertically provided with through holes, the vertical damping assembly is mounted in the through holes, the course damping pad is mounted between the outer wall, along the direction vertical to a slide rail, of the casing and the box-type cavity, and the lateral damping pad is mounted between the outer wall along the slide rail direction of the casing and the box type cavity. The damping slide block device can damp vibration of a rocket sled in three coordinate directions to provide a proper environment for rocket sled test.

Description

technical field [0001] The invention belongs to the technical field of high-speed rocket sled slide rail tests, and in particular relates to a vibration-damping slide block device used for high-speed rocket sled tests. Background technique [0002] The rocket sled rail test is a very effective ground dynamic test between the laboratory and the full-scale flight test. With the characteristics of large speed and overload range, high efficiency, safety, high repeatability and excellent economy, it has become an indispensable test equipment for identifying new theories, new technologies, new materials and new structures of various weapons and equipment, such as aviation, aerospace, weapons, Electronics, nuclear weapons and other majors have incorporated more and more rocket sled tests into basic test methods. [0003] The slider is the key component of the rocket sled. The rocket sled runs along the track at high speed by means of the slider fastened on the rail head of the sli...

AI Technical Summary

Problems solved by technology

[0006] Traditional vibration reduction measures mostly adopt the method of installing shock absorbers at the joints of the test pieces or core components that have high requirements on the vibration environment. When the size and weight of the test pieces are large and the installation space around the core components is insufficient, it is often difficult to accomplish

At the same time, in order to ensure the integrity of the test piece, the shock absorber is often installed outside it, which increases the structural weight and overall size of the rocket sled, and puts forward higher requirements for the thrust and aerodynamic shape of the rocket sled engine, resulting in design difficulties. and substantial increases in implementation costs
