The invention discloses a reciprocating stroke lead screw inerter device with an adjustable inertia coefficient, and belongs to the technical field of engineering vibration isolation. The device comprises an upper cylinder barrel, a bearing, a lead screw, a crescent pin, a lead screw seat, a lower cylinder barrel and a flywheel. According to the inerter device, two-stage adjustment of the inertia coefficient is achieved through the lead screw, the lead screw is designed to be of a structure with one lead screw and two leads, the two-stage adjustment of the inertia coefficient is achieved through switching sliding of the crescent pin in grooves of the two leads of the lead screw, and due to the fact that the grooves of the two leads are connected in an end-to-end closed-loop mode, the stroke is fixed. The device can realize two working modes, specifically, the first mode is random switching, two-stage adjustment is carried out on the inertia coefficient of the inerter according to the actual working requirement, and when adjustment is not needed, the inerter works under the inertia coefficient of a certain stage; and the other mode is fixed switching, when the inerter is in a stretched (compressed) state, the inertia coefficient is b1 (b2), and when the inerter is in a compressed (stretched) state, the inertia coefficient is b2 (b1).
Description
technical field [0001] The invention relates to the technical field of engineering vibration isolation, in particular to a reciprocating stroke lead screw inerter device with adjustable inertia coefficient. Background technique [0002] Since the inerter was proposed, it has had a huge impact on the field of vibration isolation. As a mechanical component with free movement at both ends, it solves the problem that one end must be grounded when the quality characteristic is connected to the system, and effectively introduces the quality characteristic into mechanical vibration isolation. system. [0003] With the continuous development of the inerter, it has gradually fallen into the dilemma of fixed parameters. In order to solve this problem, many inerters with variable parameters are emerging, but for mechanical inerters, in order to realize the variable inertia coefficient, the complexity of the mechanism will be greatly increased, which will increase the difficulty of pro...
