In this paper, considering the inertia of MRF, a novel method of setting up a 1D transient finite element model for a MR damper is proposed by flexibly using of the moving mesh technology, that is, de
本文运用矢量法通过对惯性矩阵的计算,发现了中心惯性主轴转子在安装过程与旋转轴发生偏差角的情况下,惯性积大小与几何尺寸的比例和偏差角大小有关,并存在旋转轴也是中心惯性主轴的特例,从而得到了旋转轴在偏差角下仍为中心惯性主轴的条件.此类现象在教学中应该引起足够重视.
结合实际社会,以举例教学为主,增强学习的趣味性.以实际事故出发,分析问题的根源.得出为什么学,怎样学,学成什么样,从而提高学生的综合素质,培养学生的创新能力.工程力学是工科专业的一门非常重要的专业基础课，只有不断深化工程力学课程建设，从理论教学、实践教学、科学研究和考核方法等方面同时进行改革，才能不断地提升教学质量，培养出高素质的工程专业人才。在教学中要强调:自主学习，勇于创新;结合实际，解决问题
