Magnet exciting coil winding method and device of magneto-rheological damper

Abstract

The invention provides a coil winding method and device of a magneto-rheological damper. The coil winding method comprises the following steps: splitting a single coil into first-class parallel-numbercoils, and splitting each of the first-class parallel-number coils into second-class parallel-number first coils; connecting and winding first-class parallel-number first coils in parallel to form second coils; and connecting the second-class parallel-number second coils in parallel to form a target coil, wherein the total number of turns of the target coil is the same as the number of turns of the single coil. The response time of current variation of the target coil or the response time of damping force variation is opposite to the variation trend of square of the product of the first-classparallel number and the second-class parallel number in the target coil. The response time of the magneto-rheological damper is shortened through increasing the first-class parallel number or the second-class parallel number; in addition, through adopting the winding manner of magnet exciting coils of the target coil, a magnetic field generated by the magnet exciting coils can be uniformly distributed in damping intervals of the magneto-rheological damper to enable the magneto-rheological damper to output force uniformly and keep force outputting balance.

Description

technical field [0001] Embodiments of the present invention relate to the field of structural vibration control, and in particular to a coil winding method and device for a magneto-rheological damper. Background technique [0002] At present, magnetorheological dampers have been widely used in many fields of vibration reduction. With the continuous expansion of its application fields, the requirements for various performance indicators of magnetorheological dampers are gradually increasing. In addition to the output damping force and adjustable range of the performance index of the magneto-rheological damper, the response time of the magneto-rheological damper is another important index. The response time of the magnetorheological damper directly determines its control effect. The shorter the response time, the more conducive to real-time control and the better the control effect. Especially under high impact loads, the action process is rapid, usually only a few hundred m...
