Continuous moving body acceleration system for strong impact test and working method thereof

Abstract

The invention discloses a moving body continuous acceleration system for a strong impact test and a working method thereof. The system comprises a moving body high-speed motion pipeline, a primary pneumatic acceleration device, a secondary pneumatic acceleration device, a moving body recovery device and a moving body arranged in the moving body high-speed motion pipeline. An air outlet of the primary pneumatic acceleration device is communicated with an initial pipe orifice of the moving body high-speed motion pipeline to drive the moving body pneumatically so as to obtain an initial speed ofhigh-speed movement in the moving body high-speed motion pipeline. An air outlet of the secondary pneumatic acceleration device is communicated with the body of the moving body high-speed motion pipeline to drive the moving body pneumatically multiple times so as to realize acceleration and high-speed movement in the moving body high-speed motion pipeline. The moving body recovery device is used for recycling a moving body ejected from the moving body high-speed motion pipeline. According to the invention, the moving body can be accelerated continuously in the strong impact test and thus the high-speed movement of the moving body in the moving body high-speed motion pipeline is realized; and the acceleration effect is good.

Description

technical field [0001] The invention belongs to the technical field of strong impact test devices, and in particular relates to a continuous acceleration system for a moving body used in strong impact tests and a working method thereof. Background technique [0002] In the strong impact experiment, it is necessary to use gas-driven acceleration equipment to accelerate the moving body to simulate and explore the motion state of the high-speed moving body. The existing gas-driven acceleration equipment has the following shortcomings: [0003] 1. The continuous acceleration effect on the moving body is not good, resulting in a large error in the strong impact test and reducing the accuracy; [0004] 2. When the moving body recovery device recovers the moving body, it is easy to cause impact damage to the moving body, resulting in the inability of the moving body to be reused, resulting in waste and increasing the input cost of the strong impact test.
