轨道客车弹性粘接技术及工艺研究

Study of elastic bonding technique and process for railway vehicle

随着对轨道客车车身舒适性、轻量化的要求越来越高,轨道客车中弹性粘接技术逐渐替代传统的铆接、焊接工艺。弹性粘接技术具有应力分布均匀、隔音和减震等优点。综述了弹性粘接技术的特征及在轨道客车制造中的应用,并以单组分湿气固化聚氨酯胶粘剂粘接为例,详细研究了弹性粘接工艺,包括粘接环境、表面处理、施胶和粘接后处理等。

With the more and bonding technique gradually replaces stress distribution, noise insulation, v technique, the use of elastic bonding t technical parameters of adhesives, and elastic bonding technique in detail, more requirements of comfort and lightweight of railway vehicle body, the elastic the traditional welding and riveting. It owns several advantages including uniform ibration damping etc. This paper introduced the characteristics of elastic bonding echnique in railway vehicle manufacturing, the curing mechanism and the important by taking one component moisture curing polyurethanes as the example, studied the including construction environment, surface treatment, bonding, bonding posttreatment.
