The invention relates to a mechanical falling body device for controlling falling acceleration and a falling simulation method, and belongs to the technical field of star soil tests. According to the device, a vertical rail is composed of four steel wire ropes, a mechanical falling body device is arranged on the vertical rail, the mechanical falling body device and the four steel wire ropes are clamped and loosened respectively, and therefore friction force between the mechanical falling body device and the steel wire ropes is changed so as to adjust the acceleration during falling. According to the mechanical falling body device for controlling the falling acceleration, the falling acceleration is controlled based on friction force, and the problem that a low-gravity test for a soil body is difficult is effectively solved. Any 0-1G gravity field environment can be generated, test conditions are provided for tests needing to be carried out under the low-gravity condition, generation of the low-gravity field is more flexible, and the test reproduction difficulty is reduced. According to the simulation method, mechanical tests of a series of star soil in a low-gravity environment are realized, so that comprehensive sounding response of lunar soil in a small-gravity environment and influence action mechanism analysis of a gravity field are realized.

    本发明涉及一种控制下落加速度的机械落体装置及下落模拟方法,属于星壤试验技术领域。该装置由四根钢丝绳组成竖向轨道,布置在竖向轨道上的机械落体装置,机械落体装置分别与四根钢丝绳实现夹紧与松弛,从而改变机械落体装置与钢丝绳之间的摩擦力以调节下落时的加速度。本发明提供的控制下落加速度的机械落体装置,基于摩擦力控制下落加速度的方式,有效解决了针对土体的低重力试验困难问题。可以生成任意0‑1G重力场环境,为各种需求在低重力条件下进行的试验提供试验条件,低重力场的生成更加灵活,降低试验复现难度。模拟方法实现星壤的系列低重力环境下的力学试验,从而实现较全面的小重力环境中月壤的触探响应以及重力场的影响作用机理分析。
