摘要：

为解决道路冰雪的问题，研制了智能感知道路主动除冰雪系统。介绍了导电橡胶复合材料的制备方法，通过室外试验确定了融雪效果，而且构建了相应的有限元模型，将主动融冰雪系统用于工程且确定了智能感知系统的阈值。结果表明，14 V电压和-8 °C条件下导电橡胶在3.17 h融化路面20 mm雪厚，可以实现低电压下快速融雪。室外试验验证了有限元模型的准确性，感知系统表明智能感知主动除冰雪系统能及时除去道路冰雪。

Abstract:

Active melting of ice and snow has gradually become an important method to solve the problem of road ice and snow. The preparation method of conductive rubber composites is produced in this paper. The snow melting effect was determined through outdoor experiments. Moreover, the corresponding finite element model was constructed. The active ice and snow melting system was used for engineering and the threshold of intelligent sensing system was determined. The results show that conductive rubber can melt 20 mm snow on the road in 3.17 h at 14 V and -8 ℃, which can realize rapid snow melting at low voltage. The outdoor test verifies the accuracy of the finite element model. The sensing system indicates that the intelligent sensing active ice and snow removal system can remove road ice and snow in time.

Key words: road engineering, active ice and snow removal system, numerical simulation, conductive rubber composite
