| Abstract: |
| Objective To study grain adhesion force test technology suitable for vacuum and radiation environment. Methods Grain adhesion force test technology was established by investigation, analysis and calculation. First of all, the grain adhesion force test technology under atmospheric conditions was investigated, and the applicability of atomic force microscopy testing method, centrifugal test method, electrostatic test method, vibration detachment test method and laser test method was comparatively analyzed. Results All the existing test methods were not suitable for the grain adhesion test in vacuum and radiation conditions. Focusing on the need of the test， the paper established the adhesion force analyzing and testing method, which could give both the charge and the adhesion force based on grain movement. Based on this method, preliminary design of test system and test device was given. Conclusion This test method was feasible and could satisfy the demand of simulant lunar dust grain adhesion force test. |
