“…The shear thickening fluid (STF) is used in the damper as an intelligent material. Liu and Hou [5] designed a variable stiffness friction damper to reduce the micro-vibration of the flywheel. Zhang [6] designed a torsional composite friction damper, which reduced the vibration damage of buildings in rare earthquakes by combining the advantages of elastic shape memory alloy (SMA) stranding and curved friction damper.…”

In order to solve the problems of low-profile accuracy and poor control stability of the satellite antenna due to axial coupling vibration, in this paper, a self-resetting friction damper is proposed to suppress axial vibration. Firstly, a self-resetting friction damper, with a lightweight, wide frequency band, and high energy consumption, is designed. The principle of dry friction energy loss of metal rubber (MR) and the effect of self-resetting of shape memory alloy (SMA) are used. Secondly, the vibration reduction mechanism model of the self-resetting friction damper is established, and the principle of damping energy dissipation is analysed. Finally, sinusoidal excitation tests of the components of the satellite antennas with self-resetting friction dampers are carried out. The axial vibration loss factor of the components of the satellite antenna with the self-resetting friction damper is calculated, and the vibration resistance performance of the damper is verified. Theoretical analysis and experimental results show that the self-resetting friction damper has a significant effect on suppressing the axial vibration of the components of the satellite antenna. It is feasible to install a self-resetting friction damper in the components of the satellite antenna to suppress the axial vibration.

A method is proposed to analyse and optimize the performance of nonlinear damping vibration isolator based on parallelogram linkage. Establish the vibration differential equation of the system, and perform Taylor expansion of the nonlinear damping coefficient, and then obtain the steady-state response of the system under harmonic excitation through methods such as perturbation method and averaging method. The displacement transfer rate curve of the steady-state response has a high degree of fitting with the curve obtained by the multi-body dynamics software, which proves the accuracy of the method. Taking the resonant peak of the steady-state response as the optimization target, and taking the high-frequency transmission rate as the constraint condition, design and optimize the rod length and damping coefficient of the mechanism. Comparing with traditional damping, the optimized nonlinear damping has a more obvious suppression effect on the resonance peak when both transmission rates of steady-state response are close at high frequencies. The analysis method in this paper is convenient to parameterize and has good programmability, which means that it provides a simple and effective new method for the parameterization and optimization design of the nonlinear damping vibration isolator based on parallelogram linkage.
