Long-term partial gravity environment simulation method based on double inclined and horizontal planes cyclical simulation device

Abstract

Partial-gravity experiments are essential for research in space science and biology. To explore the influence mechanism of partial gravity on plant growth on the ground, a cyclical simulation method of partial-gravity environment based on double inclined and horizontal planes is proposed, analyzed the variation of simulated gravity with time and established the evaluation mechanism of combining the maximum gravity acceleration with the ratio of hyper-gravity time. The experience is conducted with the method of energy compensation considering the energy loss. Taking 1/2g, 1/3g and 1/6g three kinds of partial-gravity environment as research objects, the comparison over parameters is carried out ranging from velocity, rising height, ratio of hyper-gravity time to gravity acceleration before and after energy compensation. The parameter collaborative optimization method of inclined and horizontal plane gravity simulation device is formed. This method provides technical services for long-term manned exploration on the Moon and Mars in the future.
