Abstract
The research aims to study the vibration isolation device using the elastic forces of the electromagnetic suspension. The optimum gain values of the signal feedback circuit, which minimize the impact of noise introduced by the elements of the active vibration isolation device, are determined. The possibility of developing the vibration isolation device with the control circuit coefficients found on the boundary of the stability region is considered. The paper provides the amplitude-frequency characteristics of a single-mass electromagnetic suspension.
Highlights
The consideration of additional loads, which can lead to structural instability [1, 2] or even destruction [3,4,5], is relevant under the elevated static, mechanical and thermal loads
The research aims to determine the optimum parameters of the stabilization system under the law of change of the control voltage of the active vibration isolation device
Perform the system optimization to reduce the noise introduced by the voltage converter into the active vibration isolation device (AVID) supplied with a single-mass electromagnetic suspension (EMS)
Summary
The consideration of additional loads (static, vibration, seismic), which can lead to structural instability [1, 2] or even destruction [3,4,5], is relevant under the elevated static, mechanical and thermal loads. It should be noted that both Russian [8, 9] and foreign researchers [10,11,12] have succeeded in stabilizing the electromagnetic suspension in active vibration protection devices. These results cannot be considered as a basis for the development of universal facilities capable of choosing the optimum structural solutions for vibration isolation devices with due regard to the functional area [13, 14]. Elastic forces of the electromagnetic suspension (EMS) are used to minimize the errors introduced by the elements of the vibration isolation device
