Roller-concave plate type variable stiffness self-adaptive vibration isolation device with auxiliary mass
The invention relates to a roller-concave plate type variable-stiffness self-adaptive vibration isolation device with auxiliary mass. The roller-concave plate type variable-stiffness self-adaptive vibration isolation device comprises an auxiliary mass mechanism unit and a variable-stiffness mechanism unit, the auxiliary mass mechanism unit comprises a plurality of pairs of auxiliary mass rotating nuts, the auxiliary mass rotating nuts are arranged on rotating screws in a sleeving mode, two connecting rod pieces are connected between the rotating screws and the main body rod piece, baffles are arranged on the rotating screws, and rotating springs are connected between the auxiliary mass rotating nuts and the baffles; each variable stiffness mechanism unit comprises a hexagonal structure and a roller-concave plate structure, each hexagonal structure comprises six main body rod pieces, springs are connected among the main body rod pieces, each roller-concave plate structure comprises a concave plate, a spring and a roller, and the springs are connected between the rollers and the main body rod pieces. Compared with the prior art, non-linear enhanced inertia control force and variable stiffness restoring force related to deformation amplitude, speed and acceleration can be provided for a vibration-isolated structure, and particularly, the vibration-isolation synergistic effect and the vibration-isolation deformation cooperative control effect at the deformation stage can be achieved.
本发明涉及一种具有辅助质量的滚轮‑凹板型变刚度自适应隔振装置,包括辅助质量机制单元和变刚度机制单元;辅助质量机制单元包括多对辅助质量旋转螺母,辅助质量旋转螺母套设于旋转螺杆上,旋转螺杆与主体杆件之间连接两根连接杆件,旋转螺杆上设置有挡板,辅助质量旋转螺母与挡板之间连接旋转弹簧;变刚度机制单元包括六角形结构和滚轮‑凹板结构,六角形结构包括六根主体杆件,主体杆件之间连接弹簧,滚轮‑凹板结构包括凹板、弹簧和滚轮,滚轮与主体杆件之间连接弹簧。与现有技术相比,本发明可为被隔振结构提供变形幅值、速度和加速度相关的非线性增强的惯性控制力和变刚度恢复力,尤其可实现发变形阶段的隔振增效及隔振变形协同控制效果。
