A test stand was designed to semi quantitively measure the adhesion of JSC-1/1A lunar simulant dust to materials proposed for use in the lunar surface environment. Sieved simulant <45 μm in diameter was uniformly deposited on sample surfaces. Dust adhesion was indicated as the centrifugal force created from rotation of the test stand to shed dust under high vacuum and UV exposure conditions The device generated a maximum centripetal force greater than 400 g's. Dust adhesion on aluminum, anodized aluminum, Ortho fabric and Z93P painted aluminum was observed and analyzed over a 12 step, increasing acceleration profile. At each rotation cycle, dust coverage was recorded using a camera and changes in the coverage were analyzed in post-processing to provide an indication of the adhesive force dust particles would have to overcome to be removed from the surface. Results showed that all material coverage amounts exhibited a similar shedding profile with individual plateaus occurring below 30 μm depending on material. Bare and anodized aluminum had higher adhesion values in vacuum than did the samples exposed to UV at high centripetal acceleration levels. The Z93P painted aluminum and Ortho fabric indicated the opposite, whereby UV exposed samples retained more dust at higher acceleration levels and thereby larger dust particles likely adhered to the surfaces. Ultimately, this testing indicates that the apparatus provides acceptable control and conditions to assess dust adhesion of lunar simulants. Increased precision can be attained by changes in lighting, camera orientation and clarity, and sample dust application.

设计了一个测试台，以半定量地测量 JSC-1/1A 月球模拟尘埃与拟用于月球表面环境的材料的粘附性。筛分后的直径小于 45 μm 的模拟物均匀沉积在样品表面。灰尘附着力表示为在高真空和紫外线照射条件下由测试台旋转产生的离心力以脱落灰尘。该装置产生的最大向心力大于 400 克。在 12 个步骤中观察和分析铝、阳极氧化铝、Ortho 织物和 Z93P 涂漆铝上的灰尘粘附，从而增加加速度曲线。在每个旋转周期，使用相机记录灰尘覆盖率，并在后处理中分析覆盖率的变化，以提供灰尘颗粒必须克服的粘附力才能从表面去除的指示。结果表明，所有材料覆盖量都表现出相似的脱落分布，个别平台出现在 30 μm 以下，具体取决于材料。裸铝和阳极氧化铝在真空中的附着力值高于在高向心加速度水平下暴露于紫外线的样品。Z93P 涂漆铝和 Ortho 织物表明相反，因此暴露在紫外线下的样品在更高的加速度水平下会保留更多的灰尘，因此更大的灰尘颗粒可能会粘附在表面上。最终，该测试表明该设备提供了可接受的控制和条件来评估月球模拟物的灰尘附着力。可以通过改变照明、相机方向和清晰度以及样品粉尘应用来提高精度。
