摘要

摘要 根据对自然条件下冰盖在移动载荷影响下(即在挠性重力波(FGW)激励下)波动的观测,冰盖的行为类似于弹性各向同性板。在此基础上,我们提出了一个新的方向,即在常规实验盆地中对弹性薄膜上的 FGW 冰盖变形的一些问题进行建模。弹性模型层和天然冰盖在移动载荷作用下的变形记录比较结果证实了这一技术的可能性。根据相似性和尺寸理论,获得了将模型试验数据转换为完整比例的依赖关系。据指出,进行这种模型试验的费用比在冰盆地进行试验的费用要低得多。列出了冰工程问题,在解决这些问题时可以使用所开发的 FGW 建模技术。

Modeling of Flexural-Gravity Waves in Ice Cover on Elastic Films

It is noted that, based on observations of fluctuations of the ice cover in natural conditions under the influence of moving loads, i.e., when excitation of flexural gravity waves (FGW), the latter behaves similarly to an elastic isotropic plate. On this basis, a new direction has been proposed in modeling some problems of deformation of the FGW ice cover on elastic films in conventional experimental basins. The possibility of this technology is confirmed by the results of comparing records of deformation by moving loads of an elastic model layer and a natural ice cover. Based on the theory of similarity and dimensions, dependencies were obtained for converting model test data to full scale. It is noted that the costs of conducting such model experiments are disproportionately less than the costs of conducting experiments in ice basins. Ice engineering problems are listed, in solving which the developed FGW modeling technique can be used.

期刊介绍: Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
