[0003] Chinese patent application 201410650452.4 discloses a ball screw type inerter with mechanical variable inertia coefficient and variable inertia coefficient. Chinese patent application 201510461811.6 discloses an integrated screw electromechanical inerter. The above two inerters Both involve ball screw type inerters. When the screw nut changes the direction of movement, it drives the lead screw to change the direction of rotation. The flywheel and the lead screw of the above two inerters are rigidly connected. However, during the rotation of the flywheel, inertial force is generated, and the instantaneous change of direction will cause impact on the screw and the screw nut, resulting in time lag, increasing the nonlinear factor of the inerter, and having a certain impact on the performance of the inerter

Abstract

The invention provides a stable-switching ball screw type inerter device. The stable-switching ball screw type inerter device comprises a first mounting part, a second mounting part, a first cylinderbarrel, a second cylinder barrel, a screw nut, a screw, a flywheel A, a flywheel B, a one-way clutch A and a one-way clutch B and is characterized in that the screw is mounted between the first cylinder barrel and the second cylinder barrel in a penetrating manner, one end of the screw is rotatably mounted in the first cylinder barrel, and the other end of the screw penetrates the screw nut fixedly mounted on the second cylinder barrel and is coordinated with the screw; the first mounting part is mounted at the left end of the first cylinder barrel, and the second mounting part is fixedly mounted at the right end of the second cylinder barrel; when the motion direction of the nut instantly changes, only one of the two flywheels synchronously rotates along with the screw, flywheel impact, caused by rotation direction change, on the screw during switching is avoided effectively, stable switching is achieved, influence of nonlinear factors is small, and the performance of the inerter device is improved effectively.

Description

technical field [0001] The invention relates to an inerter, in particular to a ball screw type inerter with steady switching and no impact. Background technique [0002] In 2002, Professor Smith of the United Kingdom invented the mass element with two ends - the inerter. With the research on the inerter, it has been used in the fields of automobile suspension, buildings, trains, robots and so on. Through the research, it is found that the inerter is used in In the vibration isolation system, the vibration isolation performance of the system can be effectively improved. Therefore, the research and invention of the inerter has great development potential in the field of vibration transmission. [0003] Chinese patent application 201410650452.4 discloses a ball screw type inerter with mechanical variable inertia coefficient and variable inertia coefficient. Chinese patent application 201510461811.6 discloses an integrated screw electromechanical inerter. The above two inerters...
