Title:
PIPE VIBRATION-CONTROLLING SMART DAMPER CAPABLE OF COMPENSATING FOR THERMAL DISPLACEMENT
Document Type and Number:
WIPO Patent Application WO/2019/054597
Kind Code:
A1
Abstract:
The present invention relates to a smart damper capable of compensating for thermal displacement generated by a temperature change of a pipe and capable of absorbing shock by controlling vibration and, more specifically, to a pipe vibration-controlling smart damper capable of compensating for thermal displacement, the smart damper comprising a vibration damping part and a thermal displacement compensation part, wherein the vibration damping part is a polyurethane elastic member and performs vibration and thermal displacement compensation, and the thermal displacement compensation part, which has a compression spring and an impact sleeve and is at both sides of the vibration damping part, primarily compensates for thermal displacement before the vibration damping part performs thermal displacement compensation, performs vibration and thermal displacement compensation in two stages through the vibration damping part and the thermal displacement compensation part so as to stably absorb vibration or shock, has a structure simpler than that of a conventional damper, has low costs for materials, has excellent durability so as to reduce production, maintenance and management costs, and is provided with shape memory alloy wires such that the restoring capacity of the compression spring and the polyurethane elastic member is high.
