永磁发电机动偏心故障下关键部件振动特性

Zhendong Ceshi yu Zhenduan
针对永磁同步发电机气隙动偏心故障下关键部件振动特性研究不足的问题，提出便捷经济的发电机动偏心实验模拟方案，分析发电机定子、定子绕组与转子在动偏心故障前后的振动特性。首先，通过建立理论解析模型，揭示动偏心对定子单位面积磁拉力、绕组电磁力与转子不平衡磁拉力及相关部件振动特性的影响机理；其次，构建有限元模型并进行电磁与谐响应分析，阐明定子、绕组及转子的激振力与振动响应特性；然后，搭建基于轴承内圈更换的动偏心实验模拟装置并进行关键部件的振动测试，实现不同偏心程度下的实验验证；最后，对理论 ...

花瓣形钢管混凝土柱轴压受力机理和承载力研究

Jianzhu Gangjiegou Jinzhan
花瓣形钢管混凝土柱具有造型美观的优点，为具体研究其受力机理和承载力，定义了其截面组成，提出了截面偏移比和截面对称系数以反映花瓣形截面性质，提出在花瓣柱中设置十字形加劲肋以增强其组合效应。基于某工程中墩柱和有限元模型，研究了花瓣形钢管混凝土短柱在轴压荷载作用下的受力机理，分析了加劲肋厚度、混凝土强度、钢材强度、加劲肋开孔直径和间距等参数对轴压性能的影响，研究了加劲肋厚度与钢管壁厚的匹配关系。根据理论分析和大量有限元参数分析结果，建议了加劲肋厚度与钢管壁厚之比和钢管名义径厚比的取值范围 ...
