FIELD: machine building.
SUBSTANCE: invention relates to the field of machine building. Self-tuning shock absorber contains pneumatic cylinder, self-drilling screw mechanism, control system, safety spring, sensors for monitoring parameters of state of protection object. Ring tubular pneumocylinder is additionally installed in the system. Possibility of pressure change in pneumocylinder is implemented by means of external compressor or throttle. Non-self-braking screw mechanism is installed in the middle of annular pneumocylinder. Stem is equipped with limiter at upper end and inserted into cylindrical channel. Around the stem there is a safety screw spring fixed from above by a nut-flywheel. Frequency of dynamic damping of oscillations and conditions of locking at high frequencies of external actions are determined by ratio of elastic element stiffness coefficient and value of reduced weight of non-self-braking screw mechanism.
EFFECT: higher quality and stability of shock absorber operation.
