An exploratory study for characterizing seated body apparent mass coupled with elastic seats under vertical vibration


Several studies have established a link between exposure to vibration from vehicles and drivers’ back pain. Suspension seats can reduce these exposure levels, but to be effective, the seats must be adapted to the vibrational environment of the vehicles for which they are intended. Their design and evaluation have up until now been based on a standardized approach using a rigid seat, which is not representative of the actual work situation. The researchers will study the biodynamic characteristics of human subjects sitting on resilient seats that provide a dynamic response that is more representative of reality. The aim of this three-phase research project is to develop anthropodynamic mannekins and models of the human body that can be used to evaluate different models of suspension seats in the laboratory.
