Analysis and assessment of dynamic response to passengers during lift emergency braking

Magiera T., Kułaga P., Wójcik K.

The paper presents an analysis and assessment of recorded accelerations acting on Hybrid III dummy during emergency braking of a passenger lift. The dummy was equipped with a system of three-axis accelerometers. The type of progressive safety gear that has the shortest time of reaction and the shortest effective braking distance in its group, was chosen for tests. The tests were carried out on an emplacement, which simulated the movement of passenger lift. Tests of emergency braking were performed at variable load of a cabin corresponding to the mass of different passengers number. The cabin was dispelled by the gravity force using its free-fall. During the braking, the values of accelerations effected on individual parts of dummy, were measured. Based on them and using HIC and Nij indexes, the impact of temporary accelerations on passenger’s health was determined.

W artykule zaprezentowano wyniki symulacji ugięcia pakietów sprężyn talerzowych zastosowanych w chwytaczach progresywnych. Podjęto próbę zastosowania uproszczonej metody Wahala do oceny nośności sprężyn talerzowych.

The simulation results of Belleville springs packets deflection installed in the progressive gears were presented in the article. An attempt was made to use Wahl's simplified method to evaluate the Belleville springs loading capacity.
