Momentum and energy absorption device shared by rubber and daub

Abstract

The invention provides a momentum and energy absorption device shared by rubber and daub. The device comprises an actuating device, a guide device and a buffer device, wherein the actuating device impacts the buffer device through the guide device, the buffer device is internally provided with daub, the buffer device absorbs kinetic energy of the actuating device through the daub, and the actuating device absorbs the kinetic energy through the daub for braking; and through holes are formed in the side wall of the buffer device, and the daub absorbs the kinetic energy and then is discharged through the through holes. For the device, the braking problem of the actuating device in an ejection test is effectively solved through the buffering and guiding design of the daub -rubber pad, and during the period, all parts are not damaged by rubbing, and can be quickly reset and reused.

Description

technical field [0001] The invention relates to the field of ejection devices, in particular to a momentum and energy absorption device shared by rubber and cement. Background technique [0002] When the missile adopts the cold launch method, a corresponding actuating device is required to push the missile out of the cylinder at high speed. In order to fully study the functional performance of missiles at different ejection velocities, it is usually necessary to conduct missile ejection tests during the development and design stage. During the test, the actuating device pushes the missile forward at high speed to the set speed, the missile is separated from the actuating device, the missile continues to fly, and the actuating device needs to brake to prepare for the next test. During the braking process of the actuator, the actuator is required to brake safely, stably and reliably, without causing damage to the relevant test devices and equipment. For the existing aerodyna...

AI Technical Summary

Problems solved by technology

For the existing aerodynamic test device, the energy absorbed by the traditional cylinder buffer is limited, and it is difficult to effectively brake the high-speed and large-mass actuator within a short braking stroke.

If the actuating device is easy to rub against other parts such as sleeves and end plates, it will be difficult to meet the repeated use requirements of the test
