Human body-machine system model aiming the evaluation of vibrations transmitted to the operator

摘要

This paper deals with the human body-machine system from the point of view of the dynamic interaction having direct effects concerning vibration transmitted to the human body in case of mobile machinery cabins. Thus, criteria intended to assess vibration transmitted to human body as well as the transmitted vibration level are presented in concrete cases of some construction machines. The dynamic model for the human body-machine system when the operator is in the cabin subjected to vibration influence represents the base of the dynamic analysis that can be developed both in the linear and non-linear range with effects numerically simulated or instrumentally measured.
