Abstract

Compacted snow runways for heavy wheeled aircraft are challenging in polar regions and possible extraterrestrial infrastructure constructions. A finite element method was successfully employed to simulate a wheel landing on layered snow using the ABAQUS software package based on the Phoenix runway in Antarctica. First, the method was validated with theoretical results of several layered systems. Thereafter, basic parameters of snow were chosen with reference to the Phoenix runway's pavement. Stress distributions under landing gear were calculated for the C17, A319, B757 and Il-76 aircraft. Furthermore, the effect of subgrades on stress distributions were discussed. This study explores current knowledge on snow pavements and provides technical support for the design and construction of compacted snow runways.

通过有限元方法对压实雪跑道进行应力分析的研究

在极地地区和可能的地外基础设施建设中，重型轮式飞机的压实雪跑道具有挑战性。在南极洲凤凰城跑道的基础上，使用 ABAQUS 软件包成功地采用有限元方法模拟了轮式飞机在分层雪地上的着陆。首先，用几个分层系统的理论结果对该方法进行了验证。之后，参照凤凰城跑道的路面选择了雪的基本参数。计算了 C17、A319、B757 和 Il-76 飞机起落架下的应力分布。此外，还讨论了分级对应力分布的影响。这项研究探索了当前有关雪地路面的知识，为压实雪地跑道的设计和施工提供了技术支持。

期刊介绍： Cold Regions Science and Technology is an international journal dealing with the science and technical problems of cold environments in both the polar regions and more temperate locations. It includes fundamental aspects of cryospheric sciences which have applications for cold regions problems as well as engineering topics which relate to the cryosphere. Emphasis is given to applied science with broad coverage of the physical and mechanical aspects of ice (including glaciers and sea ice), snow and snow avalanches, ice-water systems, ice-bonded soils and permafrost. Relevant aspects of Earth science, materials science, offshore and river ice engineering are also of primary interest. These include icing of ships and structures as well as trafficability in cold environments. Technological advances for cold regions in research, development, and engineering practice are relevant to the journal. Theoretical papers must include a detailed discussion of the potential application of the theory to address cold regions problems. The journal serves a wide range of specialists, providing a medium for interdisciplinary communication and a convenient source of reference.
