Abstract: The utility model relates to a vibration isolation technical field relates to nonlinearity performance of stiffness and dampness device based on imitative leg type structure, including long, short link mechanism, level and perpendicular elastic component, long link mechanism include with the vibration isolation object connection with be used for the long linkage be connected with the vibration source, short link mechanism organizes and connects in the short connecting rod group of the long linkage in bottom in the short connecting rod group of the long linkage in top, the short connecting rod of connecting between the long linkage of long linkage in top and bottom including connecting, horizontal elastic component and perpendicular elastic component are connected respectively between short link mechanism and short link mechanism. The utility model discloses adjustable non -linear rigidity and damping characteristic can be realized, the non -linear rigidity characteristic of high bearing capacity and low dynamic stiffness is realized to the realization is located low damping, is followed the ideal nonlinear damping characteristic that the frequency changes along with the vibration displacement in other frequencies in the high damping of resonant frequency department, thereby makes the vibration isolation effect obvious, has good bearing capacity and stability simultaneously, and application scope is wide.
本实用新型涉及隔振装置技术领域,涉及基于仿腿型结构的非线性刚度阻尼装置,包括长、短连杆机构、水平和垂直弹性件;长连杆机构包括与隔振对象连接的和用于与振动源连接的长连杆组;短连杆机构包括连接于顶端长连杆组的短连杆组、连接于顶端长连杆组和底端长连杆组之间的短连杆组以及连接于底端长连杆组的短连杆组;水平弹性件和垂直弹性件分别连接于短连杆机构与短连杆机构之间。本实用新型可以实现可调节的非线性刚度和阻尼特性,实现高承载能力和低动刚度的非线性刚度特性,并实现在谐振频率处高阻尼在其他频率处低阻尼、随频率随振动位移而变化的理想非线性阻尼特征,从而使得隔振效果明显,同时具有良好承载能力和稳定性,适用范围广。
