Additional damping type nonlinear gas spring
The invention discloses an additional damping type nonlinear gas spring used for tuning mass damping. The nonlinear gas spring comprises a gas spring cavity and a damping cavity; a piston and a piston rod are arranged in the gas spring cavity and the damping cavity correspondingly, and the gas spring cavity and the damping cavity are connected with a damping sliding mass block through the piston rod; and the piston in the damping cavity is provided with a hole. The gas spring can achieve the function of integrating rigidity and damping, configuration of a TMD is simplified, the later system maintenance cost is greatly reduced, the vibration reduction frequency band of the gas spring is wide, the work stroke is shorter, the advantages are remarkable, and the defect of space limitation of a traditional TMD can be overcome.
本发明公开了一种附加阻尼式非线性气弹簧，用于调谐质量阻尼，该非线性气弹簧包括气弹簧腔体和阻尼腔体，所述气弹簧腔体和阻尼腔体内分别设有活塞和活塞杆，并通过活塞杆与阻尼滑动质量块连接，所述阻尼腔体内的活塞带孔。气弹簧能够实现刚度与阻尼一体的功能，简化TMD的配置，大幅降低后期系统维护费用，其减振频带较宽，且工作冲程更短，优势显著，能够弥补传统TMD的空间局限性缺陷。
