汽车专业学生汽车拆装实训教学改革的探索

在社会快速发展地背景下,我国有着更加广阔发展空间,当前汽车工业进步对汽车专业学生的专业技能要求越来越高,这就要求在后续教学工作中注重汽车专业学生汽车拆装实训教学工作的改革,让学生接受更加专业的学习,提升动手操作能力,并将掌握到的理论知识应用到实际,提升就业率。在教学工作中教师还应始终关注对学生安全意识、环保意识以及思维能力的培养,发挥出PBL教学手段在汽车专业课程中的利用优势,让学生在各种实验教学工作中全面掌握理论知识,形成独立思考能力、判断能力。因此,本文将围绕汽车专业学生汽车拆装实训教学改革为主题来展开分析,通过详细了解汽车专业学生汽车拆装实训教学改革的价值,再提出促进汽车专业学生汽车拆装实训教学改革的可行性对策。

Vertical shaking table tests on the structure with viscoelastic multi-dimensional earthquake isolation and mitigation devices

The viscoelastic multi-dimensional earthquake isolation and mitigation device is a new kind of passive control device, which can perform its "name-giving" task of earthquake isolation and earthquake mitigation simultaneously. In order to quantify its vertical earthquake isolation and mitigation effect on structures, firstly, shaking table tests on steel frame structures with and without the devices were carried out; secondly, analysis on dynamic characteristics and dynamic responses of the structures was also performed; furthermore, the finite element analytical results and the experimental results were compared. It can be shown from the analytical and experimental results that the devices have noticeable earthquake isolation and mitigation effect in the vertical direction.
