Performance and Optimization of a Dual-Stage Vibration Isolation System Using Bio-Inspired Vibration Isolators

Autor: Zhou Huang, Xianjie Shi, Dong Mu, Xin Huang, Weihao Tong

Publikováno v: Applied Sciences, Vol 12, Iss 22, p 11387 (2022)

This paper thoroughly investigates the performance and multi-parameter optimization of a dual-stage vibration isolation system with bio-inspired isolators (BI-DSVI) under different base excitations. The dynamic equations of the BI-DSVI are derived. T

Active vibration isolation performance of the bistable nonlinear electromagnetic actuator with the elastic boundary

Autor: Weihao Tong, Daniil Yurchenko, Junlei Wang, Kai Yang, Liquan Lin

Publikováno v: Journal of Sound and Vibration. 520:116588

This paper thoroughly investigates the broadband active vibration isolation of a bistable nonlinear electromagnetic actuator with an elastic boundary (simply named EB-bistable actuator). A new feedback control law is proposed to control the actuator'
