dc.description.abstractOtis Elevator is sponsoring the design of a feedback control elevator safety mechanism. An elevator safety acts as an emergency brake that stops an elevator car in the event of a critical system failure. Current safeties are susceptible to variable friction conditions which can cause inconsistent deceleration during stops. This project develops a new mechanical, self-adjusting elevator safety mechanism that provides a stable deceleration of 0.6g during emergency stops despite varying friction. A scaled-down prototype was developed to validate the design concept.en_US
