Research Progress on Wear Behavior of Rocket Sled Slider under High Speed and Heavy Load Conditions
The rocket skid test is technical foundation of hyper-sonic technology.Up to now it has been considered as one of the research and development hotspots in the field of high-end equipment around the world.It is particularly important to conduct the study on operation and maintenance,and damage control of the rocket skid system.As link between the rocket sled and the rocket rails,the rocket sled sliders are also the key factor for highly reliable service of rocket sled test under high speed and heavy load.The wear damage of rocket sled slider under certain service conditions not only would threaten the reliable operation and long service life safety of rocket sled system,but also has been considered as the technical bottleneck that restricting the development and application of rocket sled system.Hence,there are important theoretical value and engineering significance to investigate the wear behavior of rocket sled slider under high speed and heavy load conditions.In this review,development history and present situation of rocket sled system at home and abroad was firstly introduced.Research progress on wear behavior of rocket sled slider under high speed and heavy load conditions has been presented on basis of experimentation,simulation and combination of experimentation with simulation.Three feasible strategies of simulation methods,design and preparation of new metallic materials with high performance,surface protective coating have been prospected.This paper is expected to create a database that could offer reference for service damage behavior and control techniques of materials under extreme conditions.
