摘  要:梁的挠度和转角问题不仅是材料力学课程的重要研究内容,也是工程应用中的重要问题。为使梁正常地工作,在保证梁足够强度的条件下,同时也要有足够的刚度。因此除对应力加以限制外,通常还对梁的许可挠度和转角加以限制。研究梁弯曲时的变形规律,确定梁由于弹性弯曲而产生的挠度和转角,具有相当的实用意义。本文通过引导学生探讨分析不同计算方法之间的优劣,选择出在具体环境下快速解决问题的方法,服务于教学科研和工程应用。同时也使学生做到"举一反三、学以致用",锻炼了独立思考的能力和创新思维。The deflection and corner of beam is not only an im-portant research content in material mechanics course, but also an important issue in engineering applications. In order to ensure that the beam works properly, the beam should have sufficient stiffness under the condition of sufficient strength. So besides of stress limit, the approved deflection and corner of the beam is of-ten limited, too. To study the deformation of bending of the beam and determine the deflection and corner generated by the elastic deflection is of considerable practical significance. Through guiding students to explore the pros and cons among the different calculation methods, this paper will choose the methods to solve problems quickly under specific circumstances, so as to serve the teaching and scientific research and engineering applications. Meanwhile,it also enables students to achieve the "learning by analogy and applying their knowledge"and exercise the ability of independent thinking and innovative thinking.
