The assessment of vibration absorption capacity of elevator's passengers

The transfer function expressions for damped two degrees of freedom systems with damped vibration absorbers were used to model and simulate the dynamic response of an elevator's car. The numerical simulation is implemented in MATLAB and experimental tests are conducted. The elevator's car under various load conditions with passengers wearing different type of shoes was excited over a range of frequencies and amplitudes. The agreement of the results from experimental tests with the model predictions is analysed. The simulation model is validated and the passenger's role to act as a dynamic absorber is assessed.
