Servo type vertical shock absorber and application structure and shock absorption method of servo type vertical shock absorber
The invention discloses a servo type vertical shock absorber and an application structure and a shock absorption method of the servo type vertical shock absorber. The shock absorber comprises a motorbase plate, a servo motor, an acceleration sensor, a servo system, a traction mechanism and a mass block. In the application structure, at least one servo type vertical shock absorber is installed inside or outside a box type bridge; when the vibration surface vibrates in the vertical direction, the acceleration sensor collects the vertical vibration acceleration value of the vibration surface andtransmits the vertical vibration acceleration value to the servo system, and the servo system drives the servo motor to rotate according to the collected information so as to control the mass block to move up and down relative to the vibration surface; when the vibration surface accelerates upwards, the mass block moves downwards; and when the vibration surface accelerates downwards, the mass block moves upwards. According to the shock absorber, different capacity dissipation in one vibration period is achieved through the up-and-down motion amplitude of the mass block, vibration can be rapidly reduced, and the controllability of energy dissipation in each vibration period is high.
本发明公开了一种伺服式竖向减振器及其应用结构和减振方法，减振器包括电机底座板、伺服电机、加速度传感器、伺服系统、牵引机构和质量块；在应用结构中，将至少一个伺服式竖向减振器安装在箱型桥梁的内部或外部；当振动面产生竖直方向的振动时，加速度传感器采集振动面的竖向振动加速度值传递至伺服系统，伺服系统根据采集信息驱动伺服电机转动，进而控制质量块相对于振动面上下运动：振动面向上加速时，质量块向下运动；振动面向下加速时，质量块向上运动。本发明通过质量块上下运动幅值实现一个振动周期内不同的能力耗散，可迅速减振，每个振动周期内能量耗散可控性强。
