Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention will be further described:

[0024] Such as figure 1 Shown is the circuit model diagram of the energy recovery damper. The inductance element represents the damper coil, and its function is to generate a certain electromotive force in the circuit through the law of electromagnetic induction, and then store energy; the capacity of the capacitor should be determined according to the parameters of the specific launch device, so that the maximum recovered energy does not "overflow", and the stored energy The energy can be discharged again for related tests; the diode adjusts the positive and negative polarities according to the charging direction to ensure a path when the energy is recovered, and a circuit break when it is reversed to prevent the stored electric energy from being released and dissipated. All the above components need to change the parameters accordingly according to the specific test con...

Abstract

The invention relates to an energy recovery damper, in particular to an energy recovery damper for an electromagnetic coil launcher. The energy recovery damper for the electromagnetic coil launcher mainly recovers accelerating armatures and converts the kinetic energy of the accelerating armatures to electrical energy for storage; one or a plurality of coil windings are arranged in the last level close to the multi-level accelerating windings; the one or the plurality of coils are enabled to be connected in series with a diode, a capacitor and a resistor, so as to form a closed loop. The energy recovery damper for the electromagnetic coil launcher has the following advantages: the energy recovery damper for the electromagnetic coil launcher can recover naturally dissipated energy in launchers of the conventional multi-level coil launching devices, so as to allow related experiments to utilize the energy; the experimental cost is reduced and the energy use efficiency is improved; the energy recovery damper for the electromagnetic coil launcher is provided with significances of energy conservation and environmental protection; besides, the energy recovery damper for the electromagnetic coil launcher decelerates the launchers moving at a high speed, and enables the speed reduction of the launchers moving at a high speed to be more remarkable in the same motion process, thereby being significant for general scientific research and experiments.

Description

technical field [0001] The invention relates to an energy recovery damper, which is mainly used in the field of electromagnetic coil launch, which can realize energy recovery and deceleration of the launch body, and is especially suitable for related tests and application needs, especially for electromagnetic coil launchers energy recovery damper. Background technique [0002] Electromagnetic emission technology is the application technology of electromagnetic field theory. This technology is widely used in many scientific and technological fields (such as national defense, aviation, space technology and industry). It is a research hotspot emerging in the international academic circle in recent years. Active power technology provides new ideas. [0003] Domestic related research and equipment almost only have acceleration coils for projectile acceleration, and once the projectile passes through all the acceleration coils, it will start to decelerate, and the eddy current in...
