Large-area complex curved surface synchronous impact loading method

Abstract

The invention relates to a synchronous impact loading method for a large-area complex curved surface. The synchronous impact loading method comprises the following steps: uniformly mixing photosensitive explosive powder in a liquid dispersant; the load needing to be loaded by the target object is converted into the loading thickness of the photosensitive explosive; according to the converted charging thickness, the moving track of a spray gun in spraying operation is planned; spraying the photosensitive explosive coating on the surface of the target object according to the planned moving track by using a spray gun to form an explosive coating; drying the explosive coating on the surface of the target object; a strong flash light source is arranged, strong light generated by the light source irradiates all the explosive coatings, and synchronous detonation impact loading on the large-area complex curved surface is achieved; according to the method, the large-area complex curved surface can be synchronously detonated and loaded.

Description

technical field [0001] The invention relates to a large-area complex curved surface synchronous impact loading method, and belongs to the technical field of synchronous detonation. Background technique [0002] In some mechanical studies, it is often necessary to apply an impact load to the surface of an object at the same time. At present, the commonly used technical means is to arrange some explosives on the surface of the object to form arrays as required, and to strictly control the detonation time of these explosive arrays to achieve the maximum Possible simultaneous detonation effects. [0003] The disadvantage of this method is that if the area of ​​a single charge in the array is small, it is difficult to effectively simulate the effect of the synchronous impact load on the entire surface as a whole, which is equivalent to turning a plane into densely distributed points on this plane, and at the same time The synchronization requirements of the detonation system are...

Problems solved by technology

[0003] The disadvantage of this method is that if the area of ​​a single charge in the array is small, it is difficult to effectively simulate the effect of synchronous impact loads on the entire surface, which is equivalent to turning a plane into densely distributed points on this plane, and at the same time The synchronization requirements for the detonation system are extremely high, and it is difficult to detonate accurately and synchronously;

If the area of ​​a single charge in the array is enlarged and the entire plane is replaced by many densely distributed circles or other shapes, it is difficult to ignore the explosive detonation process in a single charge, and synchronous detonation cannot be achieved inside a single charge
