엑츄에이터가 없는 피난 장치의 제동장치 설계

초록

This paper introduces an evacuation system without an actuator and a new brake device. Skyscrapers have poor stability in a fire situation that requires a golden time. In particular, a fire in a high-rise building can be fatal to the vulnerable because it is difficult to evacuate them quickly. This study designed a device that enables the vulnerable to evacuate quickly and safely in an emergency. A mechanism that delivers beds directly downstairs was devised, making it possible to carry out independent rescue activities on each floor for rapid evacuation. On the other hand, the safety of the evacuation device was not secured because of the various weights of the vulnerable. This study designed a braking system without an actuator to overcome this. The system consisted of springs and dampers. The kinetic energy was converted to the potential energy of the springs, resulting in damping and a loss of kinetic energy. Hence, the springs and dampers act as a brake. The simulation confirmed that stability is ensured even under the weight of various vulnerable people. Because there is no actuator, it can be operated safely even in emergencies. Overall, the device enables rapid evacuation and is expected to show high utility in the evacuation of skyscrapers.
