The Rocket Sled Test Method of Load Impact Based on the Artillery Firing Principle

This paper analyzes the present situation of load impact test, briefly explains the characteristics and limitations of several commonly used load impact test methods. Introduces a low peak and long duration load impact test method based on the artillery firing principle, powered by propellant combustion, and relying on the rocket sled test facility. Elaborates the principle of the test method, briefly shows the configuration and function of the test system, and predicts the result of the load impact test using the simulation method. With a certain test, analyzes and controls the factors effecting peak and duration, compares and illustrations the load impact curve, and finally the application prospect and follow up research direction of this test method is described.
