The invention discloses an underwater simulation overweight/weightlessness environment test device and test method. The device comprises a cabin body mechanism, a liquid supply mechanism, a gas supply mechanism, a large water tank and a position detector, the position detector is used for detecting the position of the cabin body mechanism in the large water tank and sending position information to the control system; the control system is used for controlling the gas supply mechanism to inject or discharge compressed gas according to the position information provided by the position detector so as to change the volume of the cabin body mechanism; and/or the liquid supply mechanism is controlled to inject or discharge liquid to change the weight of the cabin body mechanism, the weight of the cabin body mechanism is changed through the liquid supply mechanism, so that the cabin body mechanism sinks downwards, the downward acceleration is achieved, and the whole main cabin body is in an overweight state; the volume of the cabin body mechanism is changed through the gas supply mechanism, so that buoyancy borne by the cabin body mechanism floats upwards, upward acceleration is achieved, and the whole main cabin body is in a weightless state.

    一种水下模拟超重/失重环境试验装置及试验方法,包括:舱体机构、液体供给机构、气体供给机构、大水箱和位置检测器;所述位置检测器用于:检测舱体机构在大水箱中的位置并将位置信息发送至控制系统;所述控制系统用于:根据位置检测器提供的位置信息控制所述气体供给机构注入或排出压缩气体来改变舱体机构的体积;和/或控制所述液体供给机构注入或排出液体来改变舱体机构的重量,本装置通过液体供给机构改变舱体机构的重量使得舱体机构向下下沉,具有向下的加速度,从而整个主舱体处于超重状态;通过气体供给机构改变舱体机构的体积使得舱体机构受到的浮力向上上浮,具有向上的加速度,从而整个主舱体处于失重状态。
