Description

technical field [0001] The invention belongs to the field of engineering vibration isolation, and in particular relates to an inertia-adjustable low-frequency vibration isolation device. Background technique [0002] Vibrating systems are often encountered in scientific technology and engineering research, and a vibration isolation problem exists in most engineering practices. In practical life, the human body is an extremely good vibration isolation structure. In this study, a novel passive body-excited anti-vibration structure with nonlinear inertial coupling (HBIAVS-NI) is used for its advanced vibration isolation. Use bionics to make a system including exoskeleton and inner muscles, and perform vibration isolation treatment for low-frequency vibrations whose main frequencies are generally concentrated in the low-frequency band. This kind of microvibration will have a greater impact on the confidential devices inside the structure. Therefore, the design of the low-frequ...
