发布时间:2018-10-16 18:46
【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。
[Abstract]:This paper presents a soil mechanics parameter test bench for the analysis of shovel sampling machine and excavating sampling machine. The test bench consists of two parts: shovel device and excavating device, which can realize the motion of straight line shovel and rotary scoop respectively. The results of shoveling test show that the shovel speed has little influence on the shovel force, the shovel angle and the different dense state of lunar soil have great influence on the shovel force, and the peak torque also increases with the increase of rotational speed in the digging test. The parameters of the soil mechanical properties of the surface sampler are preliminarily determined, which has a certain reference significance for the study of the mechanical properties of the interaction between the sampler and the lunar soil.
