Description
Technical Field
The invention relates to the field of buffer power generation, in particular to a buffer power generation device.
Background
With the development of technology, in the fields of vehicle suspension, space docking and the like, how to solve the problem of impact braking in the process of linear reciprocating motion and reduce the damage of impact to mechanical devices is an important point of research attention of domestic and foreign students. Aiming at the impact braking problem, the device can be used for buffering and braking by adopting viscous and visco-elastic dampers, electromagnetic and eddy current dampers and the like, but the devices have the problems of high control difficulty, final conversion of energy into heat energy consumption, low energy utilization rate and the like.
Compared with the traditional viscous and viscoelastic damper, the electromagnetic damper has no contact between the stator and the rotor in the process of generating damping force, and does not influence the dynamic response and material properties of the system; compared with the eddy current damper, the electromagnetic damper can be externally connected with an energy recovery circuit to convert mechanical energy into electric energy for recovery, and the eddy current damper can only convert energy into heat energy for consumption. In addition, the electromagnetic damper has the advantages of small noise, convenient maintenance, long service life of the system, simple working principle, convenient control, high reliability, no pollution to the environment and the like. Because of its superior performance and characteristics, electromagnetic dampers are very widely used in the engineering fields of vibration suppression, vehicle suspension systems, space docking mechanisms, braking of high-speed trains, transmission systems, and the like.
According to the electromagnetic induction theorem, when the conductive material and the magnetic field move relatively, eddy currents are induced in the conductive material, and the eddy currents excite the induced magnetic field. It is also known from lenz's law that the induced magnetic field acts to block the relative movement of the conductive material and the main magnetic field, i.e. to apply a damping force to the conductive material. Furthermore, since the resistance of the conductive material itself is not zero, the generated electrical energy will dissipate in the form of thermal energy according to ohm's law.
The electromagnetic damper is an electromagnetic device based on the principle, a rotor of the electromagnetic damper corresponds to a main magnetic field source, and the stator comprises a conductive material. The relative movement of the mover magnetic field and the stator induces a current in the stator conductors that interacts with the main magnetic field to create a damping force. From the viewpoint of energy conversion, first the mechanical energy of the electromagnetic damper mover is converted into electric energy in the secondary conductor, and then the electric energy in the secondary conductor is converted into heat energy to be released into the air or the cooling liquid.
The electromagnetic damper can be divided into an electric excitation electromagnetic damper, a permanent magnet type electromagnetic damper and a mixed excitation electromagnetic damper according to different excitation sources of the rotor. In addition, the electromagnetic damper may be classified into a linear electromagnetic damper, an axial electromagnetic damper, and a radial electromagnetic damper according to the difference of the main magnetic flux circuit thereof. The permanent magnet type electromagnetic damper has a simpler structure, and the magnetic field strength generated by the electro-excitation electromagnetic damper and the mixed excitation electromagnetic damper is larger, so that the effect of the generated electromagnetic resistance is better.
At present, a large number of researchers and engineers at home and abroad invest in researching the principle and application of the permanent magnet electromagnetic damper, but a plurality of problems are still unresolved. The key technologies of the permanent magnet type electromagnetic damper for the gun backseat are studied in terms of five aspects of overall scheme design, dynamics, energy recovery property, temperature field property and electromagnetic vibration property, but a specific mechanical structure of the actual permanent magnet type electromagnetic damper for a brake device is not provided (yellow general. Key technology research of electromagnetic novel anti-squat device [ D ]. University of North China, 2020.).
