为了训练宇航员和验证宇航员在轨任务的关键操作程序与技术指标，每一个载人航天的太空任务都必须在地面上进行飞行前的失重或减重模拟试验。现有的各种减重模拟技术都有一些缺点，需要进一步发展以满足将来更多的载人航天需求。同时，人体在无重力或低重力环境下的许多科学现象还未得到很好的理解，需作进一步的研究。研究这些科学问题也需要有新型的减重模拟技术的支持。所以一些航天大国也在不断研发提高他们的减重模拟技术。有效、安全和低费用的新型减重模拟技术很受欢迎。这个报告将介绍一种新型的用于人体的失重与减重模拟技术以及相应的失重减重模拟器。这种基于机器人学理论的多自由度减重模拟装置可让被模拟的人在作多种肢体动作（如行走，跑跳，搬物等）的时候在人体力学上有等效的失重或减重效应。减重程度可视模拟需要（如月球为、火星、空间站等）进行准确定量控制。因为该系统是一被动系统，它有自然稳定还有安全、易操作和便宜等优点。马欧教授的研究团队已在他的”失重与人体力学实验室”对该新技术已做了大量的仿真分析并研制出了一台概念样机。这些研究工作充分验证了这种新减重模拟技术的可行性。报告还将介绍把该减重技术用于医疗上的设想。

Biography:

Ou Ma received a B.Sc. degree from Zhejiang University, China, and a M.Sc. and Ph.D. degrees from McGill University, Canada. He is currently an endowed chair professor in the Department of Mechanical and Aerospace Engineering, New Mexico State University (NMSU). His research interests are in dynamics and control of multibody dynamic systems and impact-contact dynamics mainly for aerospace and medical applications. Prior to joining NMSU in 2002, Dr. Ma had worked in space industry as a senior project engineer and R&D technical lead for a number of major projects developing space robotics technologies for the Space Shuttles and the International Space Station. He also participated in several design and concept evaluation projects for satellite on-orbit servicing missions including DARPA’s Orbital Express and Germany’s DEOS Programs. Due to his extensive industrial experience, Dr. Ma is particularly interested in design innovation and interdisciplinary research. He is currently leading several basic research projects sponsored by NSF, DoD and NASA.
