摘要：从高模量沥青稳定碎石的材料组成设计出发,通过动态模量和抗压回弹模量两种力学设计参数的测定,研究了高模量沥青稳定碎石的力学性能,通过车辙试验、冻融劈裂试验、劈裂试验及疲劳试验,分析了高模量沥青稳定碎石路用性能。试验结果表明:不同类型沥青对沥青稳定碎石的动态模量影响较大,高模量沥青稳定碎石的抗压回弹模量比普通沥青稳定碎石和改性沥青碎石分别提高了约24%和19%,且高模量沥青稳定碎石具有良好的高温性能、水稳定性能和疲劳性能,但低温性能较差。

摘要：吊舱推进器兼备推进和操纵功能,可在水平面上实现360°全回转。论文基于黏流理论,采用双重滑移网格技术,在指定的吊舱推进器回转与螺旋旋转运动模式下,构建动态转舵力矩数值预报方法。研究表明:与来流速度相比,转舵速度对转舵力矩的影响很小,当J=0.5时,转舵力矩在260°附近出现最大值,力矩系数为2.384×10^(-3);转舵力矩存在2个响应频率,分别为轴频4.17 Hz和叶频20.8 Hz。研究成果对吊舱推进器转舵系统的设计具有指导意义。
