A human body load simulation exercise system

Abstract

The invention relates to a human body load simulation movement system which is characterized in that the system comprises a load dummy, a six-degree-of-freedom movement module, a movement tracking module and a feedback control module; the load dummy comprises a simulation skeleton and simulation soft tissue; a six-degree-of-freedom movement platform is adopted for the six-degree-of-freedom movement module, and the movement tracking module is a movement tracking device; the feedback control module is a computer and controls the six-degree-of-freedom movement module to drive the load dummy to move, the six-degree-of-freedom movement module is adjusted and controlled in real time through a self-adapting control algorithm according to the movement locus information of the load dummy collected by the movement tracking module in real time, and the movement locus of the load dummy driven by the six-degree-of-freedom movement module is made to be continuously close to the real person movement locus set by a user till the movement locus of the load dummy is completely the same as that of the real person. The human body load simulation movement system can be widely applied to the research process of various fields related to human body loads.

Description

technical field [0001] The invention relates to a simulated exercise system, in particular to a human body load simulated exercise system. Background technique [0002] In fields such as field survival, outdoor sports, student backpacks, army marches, and labor handling, people usually need to walk with a back load. The load on the back of the human body changes the position of the body's center of gravity, affecting the person's gait and body posture, especially when the load is too heavy or walking with a long load can easily cause physical fatigue and injury. Therefore, in the field of sports biomechanics, scholars at home and abroad have extensively carried out physiological and biomechanical research on gait, posture, fatigue, energy consumption, etc. of human body load walking. At present, most of the studies on walking with human load use the method of trial and error with real people, relying on the subjective fatigue or comfort evaluation of people, the changes of ...

Problems solved by technology

A disadvantage of this method is that there is often a certain error between the movement trajectory of the dummy and the actual movement trajectory of the human body, mainly because the movement trajectory model of the real person obtained through the actual measurement method takes the real person's torso as the center of gravity, while the six-freedom The motion of the high-speed motion platform is based on a certain space point of the motion platform as the center of gravity. Usually, the motion platform needs to be manually adjusted continuously to achieve the same center of gravity between the real person and the motion platform dummy. This manual adjustment and calibration method is complicated, time-consuming, and Difficult to control precision
