Magnetorheological damper capable of recovering heat energy and chemically generating power under power loss state

Abstract

The invention discloses a magnetorheological damper capable of recovering heat energy and chemically generating power under a power loss state. The magnetorheological damper comprises an outer cylinder barrel, a left end cover and a right end cover; chemical reaction chambers are formed at the inner sides of the left end cover and the right end cover; electrode bars are arranged in the chemical reaction chambers; an electrolyte containing cavities is arranged in the outer cylinder barrel; electrolyte is filled in the electrolyte containing cavity; a middle connection rod is arranged between aleft piston and a right piston; an inner cylinder is arranged on the middle connection rod; an excitation coil is arranged at the outer side of the inner cylinder; magnetorheological liquid is filledbetween the inner cylinder and a sealing ring and a middle cavity; an external power connector is arranged at the outer side of the outer cylinder barrel; and two ends of the excitation coil are connected with the external power connector and the electrode bars through leads. According to the magnetorheological damper, automatic compensation and power supply can be carried out under the power lossstate so as to continuously generate damp, and damping effect of magnetorheological liquid can be effectively enhanced so as to greatly improve the stability and reliability of the whole magnetorheological damper.

Description

Technical field [0001] The invention relates to the technical field of dampers, in particular to a magnetorheological damper capable of recovering heat energy and transforming students' electricity in a power-loss state. Background technique [0002] Magnetorheological fluid is a new type of multifunctional material, which is composed of magnetic particles, base fluid and related additives. When there is no external magnetic field, the magnetorheological fluid has properties similar to the behavior of Newtonian fluid. When there is a magnetic field, the internal magnetic particles are rapidly chained along the direction of magnetic force, resulting in changes in rheological properties such as viscoplasticity. The time is in milliseconds, and the magnetorheological fluid becomes viscous solid accordingly, and the whole process is reversible. According to the rheological properties of the magnetorheological fluid, it can be made into magnetorheological damper, magnetorheological c...
