“…In order to meet the higher accuracy of production processing and operations related to vibration suppression is very necessary. At present, vibration reduction methods are usually classified into four approaches: active [1][2][3], passive [4,5], semi-active [6], and hybrid [7][8][9]. Among them, low-frequency vibration is more complicated in vibration control because of its slow degradation rate.…”

Undesirable shock vibrations are widely distributed in the mechanical field. Shock damping through bionic structures is a more effective method for vibration suppression. The Elytra structure of the ladybug has the characteristics of buffering and vibration reduction, and it is an efficient structure that can realize bionic vibration reduction. Based on the analysis of the vibration absorption principle of the Elytra structure, this paper adopts the symmetric structure and frictional energy dissipation method to design an Elytra structure -like an initial circular beam damping structure. To explore the effect of different features on the vibration reduction performance, the bionic structure is studied by simulation analysis and experimental methods. In order to study the effect of the bionic structure on single and periodic vibrations, mechanical simulation analysis is performed using single impact and periodic continuous vibrations of dropping objects, and an experimental setup is built to collect the corresponding vibration signals, so as to analyze the performance of the vibration reduction structure. The results show that the designed bionic sheath-fin vibration reduction structure not only has a buffering and energy absorption effect on the instantaneous impact but also has a good suppression effect on the low-frequency continuous vibration.

“…At present, the specific implementation methods for the suppression of micro-vibration include passive vibration isolation, 11,12 semi-active vibration isolation, 13–16 active vibration isolation, 17,18 and active-passive integrated vibration isolation. 19–21 The active vibration isolation performance is mainly concentrated in the middle and low frequencies, and the passive vibration isolation performance is concentrated in the middle and high frequencies. Combining the active and passive vibration isolation technologies together, that is, the active-passive integrated vibration isolation, which can give full play to the advantages of the two vibration isolation technologies and make up for their respective deficiencies, so that the best vibration isolation effect.…”

Micro-vibration seriously affects the precision and stability of precision mechanical systems. Aiming at the micro-vibration existing in the semiconductor package positioning system, this paper first designed an active-passive integrated actuator (APIA) based on piezo-stack array, which compensated the mechanical error through the piezo-stack array to improve its positioning accuracy. Based on the APIA, a 6-PUU parallel micro-vibration suppression platform (MVSP) was designed, in which the two APIAs were combined into one and installed on the lower platform along the tangential distribution of the circle, and then the kinematic model of the platform was established. Finally, the PID control algorithm was used to conduct vibration isolation experiments on the MVSP. The experimental results showed that the MVSP had good vibration isolation performance for micro-vibration, the vibration isolation frequency band was above 5 Hz, and the attenuation of micro-vibration signals was between 18% and 64%.

The inevitable vibration caused by normal operation of the spacecraft in orbit will interfere sensitive instruments, such as space telescope, reconnaissance camera, space interferometer. Serious vibrations affect the accuracy and reliability of the sensitive instruments, even cause flight mission failed. This paper presents a hybrid 6-DOF vibration isolation platform (HVIP) with six degree-of-freedom for active vibration isolation of the space sensitive instruments. The HVIP is composed of three orthogonal vibration isolation module, which composed of the active piezoelectric actuator and passive rubber isolator. The dynamic model of the HVIP is established based Lagrange equation approach. Finally, the numerical simulations are performed to verify the vibration isolation effect of the HVIP.
