An Adaptive Expandable Flywheel With Continuously Variable Moment of Inertia

Abstract

The invention discloses an self-adaptive unfolding flywheel with continuously variable moment of inertia, which includes a flywheel mounting plate and a plurality of unfolding flywheels; the edge position of the flywheel mounting plate is provided with a number of flywheels and unfolding flywheels at intervals along the circumference of the flywheel mounting plate. The corresponding flywheel connection part; the head end of the unfolded flywheel is rotatably connected to the position close to its head end on the corresponding flywheel connection part; end stroke, and then realize the continuous variable moment of inertia of the flywheel. It realizes the continuously variable moment of inertia of the flywheel and adapts to different working conditions without adding additional devices and using additional energy; not only can the maximum moment of inertia and minimum moment of inertia be designed according to the conditions of use, but also has a wider range of The utility model has a wide range of applications, and has a compact structure without excessively increasing the occupied space of the flywheel. At the same time, the manufacturing and assembly are simple, the cost is low, and it has good engineering application value.

Description

technical field [0001] The invention relates to the technical field of flywheel type inerter vibration reduction, in particular to an adaptive flywheel with continuously variable moment of inertia, especially a continuously variable self-adaptive flywheel that can be used in a vibration reduction system including an inerter. Adapts to deployable flywheels. Background technique [0002] In 2001, Smith of Cambridge University invented the "inerter". This new mechanical element can provide a very large amount of inertia with a small structural mass. An ideal inerter element is defined as a single-channel mechanical element with two relatively independent and free-moving endpoints. The forces on the two endpoints are equal in magnitude and opposite in direction, and are proportional to the relative acceleration. According to the structural principles, inerters are divided into four categories: mechanical, hydraulic, electromechanical and electromagnetic. In addition, accordin...
