摘 要：Abstract：The invention discloses a variable-inertia and variable-damping torsion damper. The variable-inertia and variable-damping torsion damper comprises a variable-inertia assembly and a variable-damping assembly; the variable-inertia assembly comprises a left end disk, a right end cover, an inner iron core, a permanent magnet, an inner coil and variable-mass-distribution ferrofluid; and the inner coil and the permanent magnet are combined to generate a magnetic field to change the distribution and the magnitude of a magnetic field at the position of the ferrofluid, and the magnitude of rotating inertia of the variable-inertia assembly is continuously adjusted. The variable-inertia and variable-damping torsion damper can independently serve as a front end torsion damper of an internal combustion engine and can also serve as a secondary flywheel of a dual-mass flywheel to be connected with a clutch; the transmission system damping and the rotating inertia can be adjusted in a self-adaptive manner according to requirements of a control algorithm; and torsion vibration of a transmission system is effectively inhibited. The variable-inertia and variable-damping torsion damper has the beneficial effects that the structure is compact, output damping torque is large, the rotating inertia adjustment range is wide, and the dynamic response is fast; and the fuel oil economy of the internal combustion engine can be improved easily, and the variable-inertia and variable-damping torsion damper can also be applied in a zero-gravity environment of the aerospace and thus has wide application prospects in rotating type mechanical devices.
