With the increase in the MF mass, the logarithmic decay rate decreased and the order of descending velocity from large to small was surface texture 1, surface texture 2, surface texture 3 and no surface texture. At the same time, the difference between the logarithmic decay rates of the four MFSAs became smaller and gradually converged. It might be that too much MF hindered the movement of the working unit. The logarithmic decay rate of the MFSA with surface texture 1 was 0.07731 when the MF mass was 6g. With the same amplitude attenuation times, the logarithmic decay rate of surface texture 2 was 0.07053, while that of surface texture 3 was 0.07303. However, the performance of the MFSA without the surface texture was obviously worse, its corresponding logarithmic decay rate was only 0.00993. From the perspective of amplitude fading, the damping efficiency of the MFSA with surface texture 1 was 7.785 times that of the MFSA without surface texture.
