Whole body vibration during simulated flight via uncertain models and interval analysis

Abstract

An uncertain mathematical model is developed to reproduce the human-body responses to a simulated flight-induced vibration. The objective is to create a predictive model based on the anthropometric characteristics of a seated human body that can turn useful for human-centered design considerations and for the integration of liveware into digital twin models. To this end, the human body is seen as an advanced vibrating structure represented as a dynamic stochastic 4DOF model with random anthropometric values. Experimental and numerical tests are given and results are evaluated in the time and frequency domain.
