Abstract The ice on vehicles has increased the requirements of vehicular mobility, safety, and comfort, which attracts people's attention increasingly. Through analyzing the characteristics of snow and ice accumulation on vehicle mudguard, we found that the snow and ice gradually encircled the wheel, the front and rear mudguards, and the posterior side of the fender inner panel with the vehicle traveling, and its thickness decreased from bottom to top. Moreover, the splash and the initial shape of ice and snow were different on the front and rear wheels. Surprisingly, we found that the increase in wheel speed delayed the accumulation of snow and ice in general. Specifically, the rate of accumulation gradually decreased on the middle of mudguards and fender inner panels but increased the on their sides. Besides, because of elastic coatings reducing the freezing adhesive strength of a material, to reduce the negative effects of snow and ice accumulation, we proposed an anti-icing elastic surface on mudguards. The results of laboratory and field test show that the icing was delayed and more gradual after the mudguard had been completely coated with the elastic coating. This suggests that changing the surface elasticity of the mudguard could be used on anti-icing for vehicle chassis.

弹性表面对车辆上积雪和冰的影响

摘要 车辆结冰对车辆的机动性、安全性和舒适性提出了更高的要求，越来越受到人们的关注。通过分析车辆挡泥板上冰雪堆积的特点，发现随着车辆行驶，冰雪逐渐包围车轮、前后挡泥板和挡泥板内板的后侧，其厚度从从下到上。此外，前后轮的飞溅和冰雪初始形状不同。令人惊讶的是，我们发现轮速的增加总体上延迟了冰雪的积累。具体而言，挡泥板和挡泥板内板中间的堆积率逐渐降低，但两侧的堆积率增加。除了，由于弹性涂层降低了材料的冻结粘合强度，为了减少冰雪堆积的负面影响，我们在挡泥板上提出了防冰弹性表面。实验室和现场试验结果表明，在挡泥板完全涂上弹性涂层后，结冰延迟且更加渐进。这表明改变挡泥板的表面弹性可以用于车辆底盘的防冰。
