“…It encompasses various approaches, including passive isolation technology, semi-active isolation technology, active isolation technology, and active–passive hybrid isolation technology. Passive vibration isolation technology [ 4 , 5 , 6 ] is currently the most mature and widely used method, offering advantages such as a simple structure, high stability and reliability, easy maintenance, and the nonrequirement of an external energy supply. However, passive isolation largely relies on its stiffness and damping characteristics, and it cannot suppress low-frequency vibrations; it may even amplify the vibration response within the frequency band range

Micro-vibrations significantly influence the imaging quality and pointing accuracy of high-precision space-borne payloads. To mitigate this issue, vibration isolation technology must be employed to reduce the transmission of micro-vibrations to payloads. In this paper, a novel active–passive hybrid isolation (APHI) system based on a strain sensor is proposed for high-precision space payloads, and corresponding theoretical and experimental studies are implemented. First, a theoretical analysis model of the APHI system is established using a two-degrees-of-freedom system, and an integral control method based on strain sensing is presented. Then, an electromagnetic damper, active piezoelectric actuator, and strain sensor are designed and manufactured. Finally, an APHI experimental system is implemented to validate the effectiveness of electromagnetic damping and strain-sensing active control. Additionally, the control effects of acceleration, displacement, and strain sensors are compared. The results demonstrate that strain sensors can achieve effective active damping control, and the control method based on strain sensors can effectively suppress the payload response while maintaining stability. Both displacement and strain sensors exhibit superior suppression effects compared with the acceleration sensor, with the strain sensor showing greater potential for practical engineering applications than the displacement sensor.

“…In recent decades, vibration isolation technology has emerged as a vital area of research, aimed at safeguarding structures and systems against undesired vibrations [1,2]. The primary objective of this technology is to minimize or attenuate the transmission of vibrations by installing a vibration isolator between the source of vibration and the controlled system.…”

In this paper, a novel magnetorheological elastomer (MRE) isolator with a compression-torsion structure was developed to address existing challenges related to stiffness variation, damping force, and magnetic control range. Through performance testing of the vibration isolator prototype and theoretical analysis based on traditional magnetic dipole model of the MRE, the effects of applied magnetic field and compression displacement on the performance of the designed MRE isolator were systematically evaluated. The results showed that integrating the compression-torsion structure not only enhances the magneto-induced mechanical performance of the MRE but also improves the overall performance of the entire MRE isolator. The output force of the MRE isolator with a compression-torsion structure generally surpasses than that of the MRE isolator lacking this feature. The isolator’s stiffness can vary by up to 119% compared to its initial stiffness when a 2A current is applied at a compression displacement of 0.5 mm. The proposed design, combining the compression-torsion structure and the MRE isolator, offers new insights for future research and applications in the realm of MRE isolators.
