| Abstract: | The paper introduces a new type of auger drilling tool of simulative lunar soil to better understand the thermal field of drilling process,and correspondingly optimizes the drilling parameters.The thermal field distribution model was established by theory calculation with simplifying the drilling parameters;and validated by the tests.At the same time,the temperature was also tested with a thermocouple during the procedure.The result showed that the established model can better reflect the temperature distri... |
