摘要
提出了一种用于分析铲取和挖取采样机的土力学参数测试台。该测试台由铲取装置和挖取装置两部分组成,可以分别实现直线铲取运动和旋转挖取运动。利用该设备进行的铲取试验初步得出了铲取速度对铲取力影响较小,铲取角度和月壤的不同密实状态对铲取力影响较大;挖取试验中,随着转速的增加,峰值扭矩也有所增加。试验初步明确了表层采样机土力学特性的参数,这对研究采样器与月壤相互作用的力学特性具有一定的参考意义。
An experimental apparatus was designed to analyze the mechanics parameter of shovel and excavationof the lunar soil.The test bed was consisted of two parts: shovel device and excavating device,which could realize linear shovel movement and rotational excavating movement.The shovel test with this experimental apparatus proved that shovel speed had very little effect on the force of shovel while different compaction status of lunar soil and angle of shovel affected a lot of force of shovel.In the excavation experiment,with the increasing of revolving speed,the peak torque would also increase.The experiment initially confirmed the parameters of properties of soil mechanics of sampling machine on the surface layer.It could supply significant reference to the study of mechanical property of the interactions between the sampler and lunar soil.
