Description
Technical Field
The invention relates to the technical field of vibration control, in particular to an electromechanical coupling device based on ball screw inertia capacity.
Background
Inertial capacity is a double-ended mechanical element taught by Smith of the university of cambridge in 2002, the force acting on both ends of which is proportional to the relative acceleration of the two ends, and this ratio is called inertial capacity. The mechanical vibration isolation network composed of the inertial mass-spring-damper is widely applied to the fields of vehicle suspension vibration isolation, building vibration isolation and the like. Inertial volume is widely used because of relatively simple structure and relatively good effect. Currently, ball screw type inertial volume, gear rack inertial volume and hydraulic type inertial volume are mainly available. The ball screw type inertia capacity based on the flywheel proposed in the early stage converts the linear horizontal motion of the nut into the rotation of the flywheel, but the inertia moment of the flywheel cannot be actively regulated, and the effect is poor when the ball screw type inertia capacity is used for vibration reduction and energy collection.
