Abstract

The invention relates to a modeling method of an electromagnetic track launcher: simultaneously realizing the matching of the physical field and the armature velocity in the prototype and the model. Then the similarity constants of each physical quantity need to satisfy: (1) the geometric similarity constant is k; (2) the electromagnetic correlation similarity constant: the similarity constant of the current density is 1 / k, and the similarity constant of the electrical conductivity is 1 / k, and the magnetic permeability (3) The similarity constant of thermal correlation: the similarity constant of thermal conductivity is k, the similarity constant of heat capacity per unit volume is 1; (4) The similarity constant of time and kinematics: the similarity constant of time is k, and the similarity constant of density and velocity The constant is 1. The present invention realizes the matching with the analysis result of the kinematic equation; it can realize the similarity of the electric field; it can realize the matching of the physical field and the armature velocity at the same time, and can effectively simulate the physical phenomenon related to the velocity; the required materials are simple and easier to realize; Ensure the similarity of the model and prototype emitter temperature fields.

Description

technical field [0001] The invention relates to the technical field of electromagnetic launch, in particular to a modeling method of an electromagnetic track launcher. Background technique [0002] The main part of the electromagnetic rail launcher consists of two parallel rails and an armature that is in good contact with the rails and can slide freely along the rails. When power is applied to the rear ends of the two rails, the two rails and the armature conduct the drive current as part of the circuit. The armature is accelerated along the track by the ampere force, so as to obtain high speed. [0003] In recent years, electromagnetic orbital launch technology has developed the fastest in the field of electromagnetic launch technology. Because of its wide application prospects and important military significance, it has attracted widespread attention from various military powers. At present, it is generally in the stage of researching key technologies such as launch tec...
