Embodiment Construction

[0024] Hereinafter, the present application will be described in detail with reference to the accompanying drawings.

[0025] The magnetorheological damping devices / systems described herein may include magnetorheological dampers and magnetorheological braking devices. Magneto-rheological dampers, such as vehicle suspension systems, operate under linear motion conditions. In this type of magneto-rheological damper, a damping force will be applied to the system. Magneto-rheological braking devices such as smart knee prostheses work under rotational motion conditions. In such a magneto-rheological braking device, a braking torque will be generated on the system. It is worth noting that the magneto-rheological damping device / system described in this paper includes both a magneto-rheological damper and a magneto-rheological braking device.

Abstract

The invention discloses equipment and method for coordinating magneto-rheological damping / braking and energy collection in a magneto-rheological damping / braking system. The equipment comprises an allocator, a magneto-rheological damping / braking controller and an energy collection controller, wherein the allocator is configured to generate a first allocation signal and a second allocation signal according to total damping force / braking torque which is required, the magneto-rheological damping / braking controller is configured to generate a magneto-rheological instruction signal for generating the allocated damping force / braking torque in response to the first allocation signal, and the energy collection controller is configured to collect the allocated energy according to the second allocation signal.

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...
