The invention relates to a shear-torsion supporting high-impedance base which comprises first substrates. A plurality of second substrates are horizontally and fixedly connected in parallel between the first substrates. The base further comprises web plates, and each web plate comprises a first right-angle side, a second right-angle side and an inclined side. Each first substrate is in contact with one end of the corresponding second substrate, the two ends of each second substrate are vertically and fixedly connected with the corresponding first right-angle sides, a plurality of fixing holesare formed in each second right-angle side, and a reinforcing plate is further clamped and connected between every two adjacent inclined sides. The web plates are fixedly connected with the substratesto form torsional support, so that the transmission mechanical impedance in the base is improved, and the vibration quantity is reduced; meanwhile, the whole base is connected with a ship body in a shearing installation mode, the input mechanical impedance of the whole base is improved, and vibration can be effectively reduced; in addition, a horizontal panel in a traditional structure is removed, the influence of the base structure on the bending moment of the ship body is avoided, and the mass of the base is reduced; and the substrates are filled with a light damping material, so that the vibration attenuation performance is improved under the condition that the mechanical structure design of the ship body is not influenced.

    本发明涉及一种剪扭支撑高阻抗基座,包括第一基底,第一基底之间水平并列固接若干个第二基底,还包括腹板,腹板包括第一直角边、第二直角边和斜边,各第一基底接触第二基底的一端,以及各第二基底的两端均与第一直角边垂直固接,各第二直角边上均开设若干个固定孔,相邻的两条斜边之间还夹接加强板。本发明腹板与基底固接形成扭转支撑,提高基座内部的传递机械阻抗,减小振动量;同时基座整体采用剪切安装的方式连接船体,提高基座整体的输入机械阻抗,也能有效减小振动;此外去除了传统结构中的水平面板,避免基座结构对船体弯矩造成影响,也减轻了基座的质量;在基底中填充轻质的阻尼材料,在不影响船体力学结构设计的情况下,提升减振性能。
