【摘要】：建立了月球次表層取心鉆具功耗模型,制備了與真實月壤物理機械參數(shù)相近的模擬月壤作為被鉆對象,通過鉆進取心實驗對理論模型進行驗證,得到取心鉆具的功耗特性曲線并確定低能耗鉆進規(guī)程。實驗結(jié)果表明,取心鉆具鉆進功耗理論模型能夠正確反映實驗曲線的變化趨勢,可依據(jù)模型對鉆具的鉆進功耗進行預估。以保證高取心率為前提,在阻力矩允許范圍內(nèi),適當降低鉆具回轉(zhuǎn)轉(zhuǎn)速,可使取心鉆具的鉆進功耗降低。
[Abstract]:The power consumption model of lunar subsurface coring tool is established, and the simulated lunar soil which is close to the physical and mechanical parameters of real lunar soil is prepared as the drilling object. The theoretical model is verified by drilling experiments. The power consumption characteristic curve of coring drilling tool is obtained and the low energy consumption drilling rules are determined. The experimental results show that the theoretical model of coring drilling power consumption can accurately reflect the changing trend of experimental curve. Based on the model, the drilling power consumption of drilling tools can be estimated. In order to ensure high heart rate, the drilling power consumption of coring drilling tools can be reduced by properly reducing the rotary speed of drilling tools within the allowable resistance moment.
