The design of the floating baffle for Cassini tank and the analysis of restraining sloshing

摘要

In this article, a new floating plate structure with drive ring is presented, which breaks the traditional idea of installing fixed baffle in a tank. In order to analyze the performance of this anti-sloshing structure, the effect of sloshing suppression and the liquid sloshing dynamics of this structure in a Cassni tank with numerical simulation is investigated. Liquid sloshing frequencies of the floating plate with different fill ratio under the circumstances of normal weight and micro-gravity were studied. At last aiming at the liquid sloshing amplitude, the suppression effect of the floating plate and rigid ring baffle was also studied under the circumstances of instantaneous angular and Bang-Bang transverse acceleration incentives with different fill ratios. The result of the numerical simulation shows that the movable-type floating plate structures can increase the liquid sloshing frequency and can effectively absorb the kinetic energy of the liquid sloshing and reduce liquid sloshing amplitude.
