Vibration Characteristics and Modeling of Human Focused on Seated Postures

Abstract

In the development of vehicles, it is quite important to improve ride comfort. And it is closely related to vibration. So, it is necessary to understand vibration characteristics of human. However, it is hard to conduct a human vibration experiment repeatedly or for long hours because of health and ethical issues. To solve this problem, a variety of human models are structed. In this study, the human model that is focused on seated postures using MBD is introduced. In this model, two postures are evaluated, which is upright and relaxed. And dynamic characteristics of each posture can be expressed by the model.
