Self-balancing structure for medium-high pressure blast load generator

Abstract

The invention relates to the technical field of blast load generator development, and provides a self-balancing structure for a medium-high pressure blast load generator. The self-balancing structurefor the medium-high pressure blast load generator is provided with an experiment section bottom assembling tool plate pre-buried in a foundation structure at the bottom of the blast load generator. Anexperiment section cylinder base is fixedly connected above the experiment section bottom assembly tooling plate; the self-balancing structure is further provided with long pull rod assemblies and short pull rod assemblies which are evenly distributed around the blast load generator. An experiment section cylinder body, a blast cavity cylinder body, a buffer element and a top cover of the blast load generator are fixedly connected above the experiment section cylinder body base in sequence; and a plurality of explosion drivers are arranged in the blast cavity barrel. The upper ends of the long pull rod assemblies and the short pull rod assemblies can be connected with the blast cavity cylinder through a quick-opening door lower meshing fluted disc; vibration and bounce of the main body structure of the blast load generator are effectively reduced so that the blast load generator is always in a self-balancing state, and the blast load generator is protected from being damaged.

Description

technical field [0001] The invention relates to a balancing device, in particular to a self-balancing structure for a medium-high pressure explosion load generator. [0002] technical background [0003] The explosion load generator is an important experimental equipment for accurately simulating the explosion shock wave environment. It is mainly composed of top cover, explosion chamber, pressure equalization and shaping section, experiment section and other structures from top to bottom. There is an explosion driver inside the explosion chamber. Explosive drivers generate massive recoil during operation. [0004] Explosive load generators built at home and abroad usually use reaction frames and foundation anchors to balance the reaction force generated by the explosion load. For large-scale medium and high pressure explosive load generators, the reaction force may be as high as tens of thousands to hundreds of thousands of tons. To balance such a large dynamic load, for thi...

[0004] Explosive load generators built at home and abroad usually use reaction frames and foundation anchors to balance the reaction force generated by the explosion load. For large-scale medium and high pressure explosive load generators, the reaction force may be as high as tens of thousands to hundreds of thousands of tons. To balance such a large dynamic load, for this type of explosion load generator, it is necessary to design a corresponding self-balancing structure to balance the explosion reaction force
