在本文中，我们描述了一个低温，伺服控制双轴摩擦装置设计来测量冰的变形行为。该设备是专门设计的，以准确地实现和测量适用于变形的冰在地球上和结冰的卫星上的低差应力。我们可以施加的载荷范围为102 -1800 kPa，速度高达4 mm/s，分辨率分别为39 Pa和0.7 μm。精确的温度控制、测量和绝缘允许在恒定温度（-2至-30 °C）下长时间进行测试。该装置进行了测试，与各种塑料以及与多晶冰样品和结果与以前公布的值是一致的。该仪器的关键组成部分描述沿着与数据收集计划和初步结果的例子。设计的灵活性允许在一系列变形行为，包括摩擦，滞弹性和粘性的冰川学和行星应用。
In this paper, we describe a cryogenic, servo-controlled biaxial friction apparatus designed to measure the deformational behaviors of ice. The apparatus is specifically designed to accurately achieve and measure the low differential stresses applicable to deforming ice on earth and on icy satellites. We can apply loads in the range ∼2-1800 kPa and velocities up to 4 mm/s, with resolution of 39 Pa and 0.7 μm, respectively. Precise temperature control, measurement, and insulation allow testing at constant temperature (from -2 to -30 °C) for prolonged periods of time. The apparatus is tested with various plastics as well as with polycrystalline ice samples and the results are consistent with previously published values. Critical components of the instrument are described along with examples of data collection schemes and preliminary results. The flexibility of the design allows for both glaciological and planetary applications over a range of deformational behaviors including friction, anelastic, and viscous.
