| Abstract | To support future manned missions to the surface of the Moon and Mars or missions requiring manipulation of payloads and locomotion in space, a training device is required to simulate the conditions of both partial and microgravity as compared to the gravity on Earth. The focus of this paper is to present the development, construction, and testing of a partial gravity simulator which uses a pneumatic actuator with closed loop mechanical amplification. Results of the testing show that this type of simulator maintains a constant partial gravity simulation with a variation of the simulated body force between 2.2% and 10%, depending on the type of locomotion inputs. The data collected using the simulator show that mean stride frequencies at running speeds at lunar and martian gravity levels are 12% less than those at Earth gravity. The data also show that foot/ground reaction forces at lunar and martian gravity are, respectively, 62% and 51% less than those on Earth. |
