Application of Eddy Current Sensor in the Experiment of Rocket Sled

In order to measure the related mechanical data conveniently and precisely,and constantly improve the scientific,security and reliability of the rocket sled design.Based on the practice of the rocket sled,this paper gives some application of the eddy current sensor in rocket sled.Through setting up the eddy current sensor,it can get the displacement curve of rocket sled motion.Compared with other methods,it is simple,cheap and reliable.The velocity and acceleration of rocket sled can be obtained by the simple differential operation of the initial data,which can be used as a reference for the design of the rocked sled body strength.At the same time,through comparing with vehicle vibration acceleration data,we can get the relationship between the amplitude and velocity of the sled motion.This helps to solve the problem of the mechanical environment adaptability of the tested product in the rocket sled.
