Design method of vibration isolation spherical steel support containing metal rubber and support
The invention provides a design method of a vibration isolation spherical steel support containing metal rubber and the support. The design method comprises the steps that S1, the vertical design bearing capacity NS of the vibration isolation spherical steel support is determined; s2, the number n1 of the metal rubber components is determined according to the elastic load interval (Nb, Nc); s3, according to the number n1, the vertical rigidity K1 = k * n1/n2 of the metal rubber vibration isolation assembly is calculated through a formula; s4, the vertical rigidity K and the fundamental frequency f of the vibration isolation spherical steel support are calculated; and S5, whether the fundamental frequency f is smaller than or equal to f1/(20.5) or not is judged, f1 is the lower frequency limit of the dominant frequency band interval corresponding to the counter-force peak value of the vibration isolation spherical steel support caused by vehicle-induced vibration, if yes, design is completed, and if not, the metal rubber component is redesigned, and the step S2 is executed till the condition of the step S5 is met. Normal functions of the support are achieved, meanwhile, the vertical vibration isolation function is achieved, the bearing capacity can be increased only by changing the number of the standard metal rubber components, and the design bottleneck of the bearing capacity is broken through.
本发明提供了一种含金属橡胶的隔振球型钢支座的设计方法及支座，所述设计方法包括：步骤S1、确定隔振球型钢支座的竖向设计承载力NS；步骤S2、根据弹性载荷区间(Nb,Nc)来确定金属橡胶构件的数量n1；步骤S3、根据数量n1利用公式计算金属橡胶隔振组件的竖向刚度K1＝k×n1/n2；步骤S4、计算所述隔振球型钢支座的竖向刚度K及基频f；步骤S5、判断是否基频f≤f1/(2^0.5)，f1为车致振动引起隔振球型钢支座反力峰值所对应的优势频段区间的频率下限，若是则设计完成，若否，重新设计金属橡胶构件，返回步骤S2，直至满足步骤S5条件。本发明在实现支座的正常功能的同时使其具有竖向隔振功能，仅改变标准金属橡胶构件数量即可实现承载力的增加，突破了承载力的设计瓶颈。
