Damping nonlinear and segmented rigidity nonlinear energy trap
The invention relates to the technical field of dynamic vibration absorption, in particular to a damping nonlinear and segmented rigidity nonlinear energy trap. The vibration damping device comprises a system to be subjected to vibration damping 1, a suspender 2, a node 3, a cantilever rod 4, a mass block 5, a viscous damper 6, a suspender 7 and a rack 8. According to the device, the two symmetrical racks are arranged on the upper portion and the lower portion of the cantilever rod 4, and the multiple blocking strips a, b and c are arranged on the racks, so that the aim of piecewise linear rigidity is achieved, traditional cubic rigidity is replaced, and better practicability is achieved. The two viscous dampers connected with the mass block are obliquely arranged so that nonlinear damping force can be provided, and the energy dissipation capacity can be better provided. The application of the nonlinear damper is improved through simple damping nonlinearity and segmented rigidity, and the nonlinear damper has obvious broadband vibration reduction capacity and practical engineering significance.
本发明涉及动力吸振技术领域，更具体地，涉及一种阻尼非线性和分段刚度非线性能量阱。该减振装置包括包括待减振体系1，吊杆2，节点3，悬臂杆4，质量块5，粘滞阻尼器6，吊杆7以及齿条8。该装置通过在悬臂杆4上下设置两个对称的齿条，以及在齿条上设置多个挡条a、b、c，以达到分段线性刚度的目的，从而代替传统的立方刚度以达到更好的实用性。与质量块连接的两个粘滞阻尼器倾斜放置从而提供非线性阻尼力，以更好地提供耗能能力。本发明通过简单的阻尼非线性和分段刚度以提高非线性阻尼器的应用，其具有明显的宽频减振能力和实际工程意义。
