Bidirectional limiting type SMA spring friction composite damper
The invention discloses a two-way limiting type SMA spring friction composite damper which comprises a damping box body. The first energy dissipation part comprises an SMA spring energy dissipation device and a damping device which are arranged in the first direction, a main transmission mechanism and an auxiliary transmission mechanism of the spring energy dissipation device can respond to external force in the first direction to promote an SMA spring set to stretch or compress so as to dissipate energy, and the damping device can dissipate energy through friction force; the second auxiliary transmission part can respond to external force in the second direction to drive the main transmission mechanism to move relative to the auxiliary transmission mechanism, and then the spring set is promoted to be stretched or compressed; the temperature control device can adjust the temperature in the damping box body so as to change the damping coefficient and rigidity of the spring set and achieve self-resetting of the damper. Compared with the prior art, the energy dissipation and shock absorption effects in the horizontal direction and the vertical direction can be achieved, the better energy dissipation effect on shock absorption and shock resistance under the complex vibration condition is achieved, and resetting is easy.
本发明公开了一种双向限位式SMA弹簧摩擦复合阻尼器，其包括：阻尼箱体；第一耗能部分，包括沿第一方向布置的SMA弹簧耗能装置和阻尼装置，弹簧耗能装置的主传动机构和副传动机构分别能够响应于沿第一方向的外力而促使SMA弹簧组拉伸或压缩从而耗能，阻尼装置能够通过摩擦力耗能；第二辅助传动部分，其能够响应于沿第二方向的外力而驱使主传动机构相对于副传动机构运动，进而促使弹簧组拉伸或压缩；温控装置，其能够调节阻尼箱体内的温度，以改变弹簧组的阻尼系数和刚度并实现阻尼器的自复位。本发明相比于现有技术，能够实现水平和竖直两个方向上的耗能减震作用，对于复杂振动条件下的减震抗震具有更好的耗能效果，且易于复位。
