Problems solved by technology
Since the internal impact reduction design of the separation device involves many factors, such as adjusting the amount of charge or burning rate, designing the internal buffer structure, and adjusting the driving work method, it is not a convenient and quick way
And reducing the assembly preload directly affects the connection strength and stiffness of the cabin structure, which is not desirable in actual work

The invention discloses an explosive bolt protection device for reducing impact. An explosive bolt is used for connecting a front-section cabin body and a rear-section cabin body, and a screw rod of the explosive bolt is arranged in the rear-section cabin body. The protection device comprises a protection box and a buffering inner pad, wherein the protection box is installed in the rear-section cabin body, the screw rod of the explosive bolt is arranged in the protection box, and the buffering inner pad is installed on the inner side wall of the protection box. The explosive bolt protection device is fixed on the front-section cabin body through using flat nuts and a flat cushion pad, and the flat cushion pad plays a role in buffering impact response; then the front-section cabin body and the rear-section cabin body are connected together through using inclined nuts, spring washers and flat washers; and a special-shaped buffering pad is adhered to the inner top surface of the protection box, and then the protection box and the buffering inner pad are mounted on the end surface of the rear-section cabin body together, so that the effects of restraining the explosive bolt bar and reducing the separation impact response are achieved together.
Description
technical field [0001] The invention relates to the technical field of explosive bolts, in particular to an explosive bolt protection device for reducing impact. Background technique [0002] Explosive bolts have the characteristics of small size and high energy density, and are often used in the connection and separation unlocking devices of missiles and rockets. Since the explosive bolt is a device driven by the explosion of explosives, it will generate a large impact load on the front and rear cabins, especially near the end faces, during the separation and unlocking process. If no impact reduction measures are taken, it may damage electronic equipment, Thin structures or brittle material structures, etc. pose a hazard. [0003] With the development of space vehicle connection and separation technology, it is more and more important to reduce the shock response of the separation device. The commonly used methods to reduce the impact response mainly include the internal ...
