| 摘 要： | 针对月面综合钻进试验台模拟月壤利用率和试验效率低的问题，提出一种主动送土试验台的设计方案，满足月面钻采作业机具的取芯特性专项验证需求。该方案利用无轴螺旋作为模拟月壤传送的核心部件，采用集成料斗实现难流动物料连续送料的功能，通过无轴螺旋转动主动将模拟月壤垂直送入取芯机构，代替综合钻进试验台钻取月壤的作用，可以实现多种级配模拟月壤的定量和定压输送。为了验证设计参数的正确性，利用EDEM离散元分析模拟月壤输送特性，并开展了试验验证。结果表明：以无轴螺旋作为主动送土机构的核心单元，可实现主动送土试验台自主、高效率地进行模拟月壤输送模拟多种取芯工况，为工程部门钻采作业机具研制定型提供性能参数验证的依据。

| Abstract: | Aiming at the problem of lunar soil utilization and low test efficiency for the lunar surface integrated drilling test rig,a design scheme of the active soil feeding test rig is proposed to meet the special verification requirements of the coring characteristics of lunar drilling and mining equipment. The shaftless spiral is utilized as the core component of the simulated lunar soil transportation,and the integrated hopper is adopted to realize the continuous feeding of the difficult-to-flow material. The shaft-free spiral rotation is used to actively send the simulated lunar soil vertically into the coring mechanism instead of the integrated drilling test bench. By drilling the lunar soil,it is possible to realize quantitative and constant pressure transport of various grading simulations of lunar soil. In order to verify the correctness of the design parameters,EDEM discrete element analysis is used to simulate the characteristics of lunar soil transport,and experimental verification is carried out. The results show that the shaftless spiral can be used as the core unit of the active soil feeding mechanism,and the active soil feeding test bench can be used to simulate the lunar soil transport simulation of various coring conditions independently,and develop the drilling equipment for the engineering department. |
