A controllable and intelligent magnetorheological pulse generator

Abstract

The present invention relates to a controllable intelligent magnetorheological pulse generator. The generator comprises an upper chamber A, a lower chamber B, a piston (22) and an elastic body (23) which are located inside the chambers respectively; the housing (21) and the piston (22) of the chamber B (20) are formed by solidifying magnetizers (17) and a plurality of magnetic separation bodies (18); a gap between the chamber B (20) and the piston (22) is filled with a magnetorheological fluid; the housing (21) outside the chamber B (20) is wound with an electromagnetic coil (19) which is connected with alternating current; a magnetic field generated by the electromagnetic coil (19) passes through vertically a gap between the top of the chamber B (20) and the piston (22); the elastic body(23) is located in the chamber A (10); and one end of the elastic body (23) is connected with the upper end portion of the piston (22), and the other end of the elastic body (23) is connected with thetop of the chamber A (10). According to the controllable intelligent magnetorheological pulse generator of the invention, the strength of the magnetic field can be changed through changing the magnitude of current, so that the stiffness and damping of the magnetorheological fluid can be changed, and the top output waveforms of the chamber A can be controlled to be pulse waveforms.

Description

technical field [0001] The invention relates to a pulse waveform generator, in particular to a pulse generator controlled by magneto-rheological fluid. Background technique [0002] With the rapid development of today's information age, there are more and more types of electronic products, and the internal structure is becoming more and more complex. With the gradual popularization of electronic products in daily life, people will use electronic products for various leisure activities. Interaction, which means that electronic products must be able to work normally in various environments, so generally electronic products are required to do various tests when they leave the factory, simulating the working conditions in various situations in the real environment. [0003] There are various forms of mechanical force on electronic equipment in the actual working environment, such as vibration, impact, centrifugal force, friction force generated by mechanism movement, etc. Among ...

Secondly, the hydraulic servo system is used more often to control the movement of hydraulic actuators to realize the control of its motion acceleration. However, due to the slow response speed of the hydraulic system (especially the hydraulic system with large flow rate), it is difficult to achieve real-time control.
