METHOD AND DEVICE FOR PROTECTING OBJECT AGAINST RESONANCE OSCILLATION Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: device comprises air flexible members made of rubber-cord shells and mounted with an interference fit and system for automatic adjustment of the frequency of natural oscillations of the swing pendulum suspension by changing pressure in the working chambers of the double-action air actuator. The double-action air actuator is made of the shells. The system is provided with control unit whose input is connected with the outputs of the ADC units of accelerometers and pressure gauges through the data bus of the ADC. The accelerometers are mounted at the site of suspension of the rigid pendulum and sites of coupling of air flexible members to the load-carrying structure of a vehicle. The pressure gauges are connected with the working chambers of the air flexible members. The output of the control unit is connected with the input of the DAC unit through the bus of the output data. The outputs of the DAC unit are connected with the inputs of power amplifiers, electromechanical converters, and air distributing devices connected in series. The method comprises using the device proposed.

EFFECT: enhanced precision of angular stabilizing.
