Description

Technical Field

[0001] The invention relates to the technical field of impact test equipment, in particular to a high-seal rotary pressure ring assembly. Background Art

[0002] Impact testing is generally a test method to determine the safety, reliability and effectiveness of military and civilian equipment when subjected to external impact or action. The impact test bench is mainly used for mechanical environmental testing of products. It can simulate actual impact pulses and impact energy, and simulate non-repetitive impacts that products are expected to suffer during use, loading and unloading, and transportation, so as to determine the product's adaptability to various impact environments.

[0003] At present, most impact test equipment is implemented by free-fall impact testers driven by gravity. However, for impact tests of certain specimens, horizontal impact must be used. Among them, the high-frequency vibration control mechanism that generates impact force plays a major role. The current horizontal impact test bench uses the deformation energy of the elastic rope as the power to generate the required initial impact velocity. Because it relies on the deformation energy of the elastic rope to accumulate energy, as the number of uses increases, the elastic rope gradually wears out, and its elastic coefficient decreases accordingly. When it reaches a certain level, it needs to be replaced, and the maintenance cost is high. Therefore, there is now a high-frequency vibration control mechanism that uses a cylinder to achieve it. However, in this high-frequency vibration control mechanism, it is necessary to ensure that the rotating distribution wheels are relatively sealed. For this reason, we propose a high-seal rotating pressure ring assembly. Summary of the invention
