Abstract

In prediction of the dynamic behaviour of an elevator car system, it is important to take into account the influence of passengers’ behaviour in the car. In this paper a simulation model is extended to analyse the influence of various loading car conditions on the dynamic response of the elevator system. This involves the investigation into the dynamic response of the car with different loads. An experimental rig with a rectangular elevator platform fixed on the top of four silent blocks attached to a shaker is designed to conduct experimental tests. The car is excited over a range of frequencies and amplitudes. A number of passengers wearing different type of shoes in the car are investigated. The transmissibility measurements are carried out with a harmonic excitation applied first to an empty car and then to the car with a number of passengers. The excellent agreement from experimental tests with the model predictions is achieved. The passenger’s role to act as a dynamic absorber is assessed and recommendations to achieve the best ride quality under load conditions are provided and summarised.
