Double piezoelectric semi-active inertia-capacitance damper
The invention relates to the technical field of vibration control, in particular to a double piezoelectric semi-active inertia-capacitance damper. The double piezoelectric semi-active inertia-capacitance damper comprises a cylinder and a ball screw and further comprises a first piezoelectric driver and a second piezoelectric driver. One end of the ball screw penetrates the cylinder and is locatedin the cylinder, a flywheel is in transmission connection to the ball screw, the first piezoelectric driver is arranged on the cylinder, a first friction block is arranged on the first piezoelectric driver, and the first friction block corresponds to the flywheel. The second piezoelectric driver is arranged on the end part of the ball screw, and a second friction block is arranged between the second piezoelectric driver and the inner wall of the cylinder. The double piezoelectric semi-active inertia-capacitance damper adjusts the inertia-capacitance coefficient in real time by means of an adjustable frictional force generated by electro-deformation of the piezoelectric drivers, so that the double piezoelectric semi-active inertia-capacitance damper has a wider application range and is better in vibration attenuating effect.
本发明涉及振动控制技术领域，具体涉及一种双压电半主动惯容质量阻尼器，包括筒体和滚珠丝杠，还包括第一压电驱动器和第二压电驱动器，所述滚珠丝杠的一端穿过筒体、位于筒体内，滚珠丝杠上传动连接有飞轮，所述第一压电驱动器设置在筒体上，第一压电驱动器上设置有第一摩擦块，所述第一摩擦块与飞轮相对应；所述第二压电驱动器设置在滚珠丝杠的端部，第二压电驱动器与筒体内壁之间设置有第二摩擦块。本发明利用压电驱动器电致变形产生的可调节摩擦力来实时调节惯容系数，具有更广的适应范围，减振效果更好。
