Description
Technical Field
The invention relates to the technical field of equipment tests of weapon equipment systems, in particular to a method and a system for testing and simulating vibration separation of shrapnel under an overload condition.
Background
The shrapnel separation technology is one of core technologies of missile launching, and bullets are conveyed to a specified position through a mother bomb and are thrown under specific attitude and overload conditions. The ground verification technology is one of the difficulties of the shrapnel separation technology. In the ground separation test, a bullet is usually thrown after a mother bullet is fixed or the mother bullet is directly thrown freely from high altitude, and the bullet is released in the free falling process (0g overload) of the mother bullet. The test method can only simulate delivery overload of 1g and 0g, and has poor practicability and poor space-to-ground consistency.

However, in order to accurately simulate the vibration of the parent bomb in the separation process, a method of applying vibration through a vibration table in the separation process of the parent bomb is often adopted in a ground test, but the overload of the parent bomb under the test method is limited to 1g, and the actual separation overload cannot be simulated.
Therefore, a novel ground test method is needed in the industry, which can simultaneously simulate the vibration and overload of the primary bomb in the separation process of the primary bomb, so as to enhance the ground-air consistency of the test and improve the confidence of the ground test.
