摘　　要：设计了一种参数化驱动的新结构的伸缩装置.在结构上采用焊接加强筋和N型钢板等方式,减少车辆和桥梁在伸缩装置对接处的震荡噪音,提高车辆的舒适度和桥梁的可靠性,同时使用螺纹钢,加大与混凝土的接触面积,提高此装置的承载能力和使用寿命.装置结构简单,加工难度低,安装和维护简单.A new expansion device with parametric drive is designed. This device can reduce noise between vehicle and bridge expansion device by improving its structure, including welding stiffeners and N type steel plates. Furthermore, this kind of improvement can enhance the comfortableness of vehicle and the reliability of the bridge. Meanwhile, the rebar increases the contact area of concrete to improve the force bearing capacity and service life. This device has the advantages of simple structure, low processing difficulty, convenient installment and maintenance.
