According to the inertial energy feedback vibration isolation system, through matching of different devices on an inner gear of an energy feedback device, change of inertial coefficients or energy recovery is achieved. Through different matching of a flywheel and a motor on the inner gear of the energy feedback device, change of the inertial coefficients of the three levels of large, medium and small and the energy recovery degrees of the two degrees of strong and weak can be achieved, the principle is simple, and the scheme is easy to implement. According to the scheme, the engineering application problem that energy of a mechanical inertial container is difficult to recover is solved, the structure is simple, and the practical application value is achieved.

Description

technical field [0001] The invention relates to an inertial energy feeding vibration isolation system for smart vehicles, in particular to a vibration isolation system coupled by a mechanical ball screw inerter and a vibration energy recovery device. Background technique [0002] The concept of "inertia" was first proposed by the Smith scholars of the University of Cambridge, UK. Based on the second type of electromechanical similarity theory of "force-current", the inertial vessel is defined as a two-terminal element. proportional to the relative acceleration of the endpoints. Its dynamic expression is: F is the force exerted on the two ends of the inerter, v 1 , v 2 is the speed of both ends, b is defined as the inertia coefficient, which is an important physical quantity to characterize the inerter. [0003] The birth of the inerter solves the single-end problem that the mass element must take the center of the earth as the reference system. The new mechanical vibrat...
