An Active Compensation Method for Somatosensory Micro-low Gravity Simulator

Abstract

The invention discloses an active compensation method for a somatosensory micro-gravity simulation device. The somatosensory microgravity simulation device includes a gravity balance component and a buffer component that provides buffer potential energy to the gravity balance component to at least partially balance the body's gravity. The active compensation method includes: S1: obtaining the additional torque generated by the micro-low gravity simulation device; S2: outputting the compensation torque in the opposite direction to the somatosensory micro-gravity device according to the additional torque. The invention outputs reverse compensation torque according to the obtained additional torque, so that the effect of astronauts walking in the training system is consistent or close to the actual walking effect on the surface of the moon and Mars, improving the efficiency of active compensation and improving the accuracy of device simulation .

Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to an active compensation method for a somatosensory low-gravity simulation device. By performing low-gravity walking training on the surface of the earth, a space station can be simulated in other weightless environments on the surface of the moon and Mars walking training to adapt to the low-gravity environment on the surface of the moon and Mars. Background technique [0002] With the development of aerospace technology, all manned space exploration activities not only require further innovation and development in aerospace engineering, but also require training for astronauts to help them become familiar with microgravity or low gravity for missions in space or alien planets environment. At present, the experimental systems for astronauts to simulate the low-gravity environment on the ground mainly include free fall, parabolic flight experimental system, neutral ...

AI Technical Summary

Problems solved by technology

However, since the spring group of the gravity simulation device is composed of multiple springs, the total mass can reach tens of kilograms. At the same time, the gravity of the device itself and the gravity of the astronauts will inevitably have frictional moments and moments of inertia. The gravitational moment, frictional moment and inertial moment are sometimes very large, so how to effectively compensate the gravity, inertial force and frictional force in the device is an important issue to be solved urgently in the micro-low gravity simulation device
