铰链四杆连杆机构结构简单,并且构件的基本形状是杆状,便于实现远距离的运动传递,因此,铰链四杆连杆机构得到了广泛的具体的应用。它作为常用机构中应用最广的一类,为学习其他机构提供了分析方法,也是学生今后使用、改造各类机械的理论基础。这一部分内容涵盖的知识点多,理论性较强,是前两节内容的深化和提升,又是后面学习铰链四杆机构演化的基础和铺垫,并对生产实践起着重要指导意义。那么在教学中如何选择教学方法来提高教学效率呢?一、课前自制模型,调动学生学习兴趣课前教师布置学生按要求自己制作模型。根据教师的要求每
The hinge four-bar linkage has a simple structure, and the basic shape of the component is a bar, which is convenient for long-distance movement transmission. Therefore, the four-bar hinge mechanism has been widely and specifically used. As the most widely used category in common institutions, it provides an analytical method for learning other institutions and is also the theoretical basis for students to use and transform various types of machinery in the future. This part of the content covered more knowledge, more theoretical, is the deepening and upgrading of the first two sections, but also to learn the hinge behind the evolution of the four-agency basis and bedding, and plays an important guiding role in production practice. So in teaching how to choose teaching methods to improve teaching efficiency? First, pre-class model, to mobilize students’ interest in learning Before class, teachers arrange students to make their own models as required. According to the teacher’s request
