Description

technical field

[0001] The present application relates to devices and methods for coordinating magnetorheological damping / braking and energy harvesting (EH) in magnetorheological (MR) damping / braking systems. Background technique

[0002] Magnetorheological fluids are smart materials that exhibit a rapid, reversible, and tunable transition from a free-flowing state to a semi-solid state within milliseconds under an applied magnetic field. Magnetorheological fluids are very promising for semi-active vibration / brake control because they provide a simple and fast response interface between electronically controlled devices / systems and mechanical devices / systems.

[0003] figure 1 A schematic diagram of a typical magnetorheological damping system with a semi-active control system is shown. Such as figure 1 As shown, the magnetorheological damping system 100 includes a dynamic sensor 110 , a system controller 120 , a damper controller 130 , a current driver 140 , a magnetorheo...
