| Abstract: | Aiming at defects of poor suppression of low frequency vibration for traditional passive vibration isolators, a new type electromagnetic-rubber active-passive integrated vibration isolator was designed.Its vibration reduction performance was evaluated through studying its output force characteristics.Firstly, the equivalent magnetic circuit analysis method was used to design and simulate its magnetic circuit structure, perform its dynamic analysis, and obtain its electromagnetic force calculation formula.Furthermore, based on the software COMSOL, dynamic simulation and analysis were done for the output force of the actuator to clarify effects of current and its frequency on output force characteristics.Finally, the characteristics test results were compared with simulation ones. |
