舰艇总纵弯曲强度实验教学设计与实践

为提高学生对舰艇总纵弯曲强度知识的掌握和运用,针对舰艇强度课程中舰艇总纵弯曲强度这一关键和难点教学内容,根据舰艇结构的实际特点,设计了箱形船体梁总纵弯曲强度实验教学模型和教学内容,探讨了实验教学实施步骤。教学实践表明,实验直观地再现了舰艇的总纵弯曲、局部弯曲及其叠加问题,通过实验大大增强了学生对知识点的理解和实践能力,激发了学生的学习兴趣。

Experimental teaching design and practice of warship longitudinal bending

In order to enhance student＇s applying ability of the warship longitudinal bending knowl- edge, box beam for experimental teaching and contents of experimental course were designed, accord- ing to the characteristics of warship structure, focused on longitudinal bending strength, which is the key and difficult contents of warship strength course. Implementation steps of experimental course were discussed. Practical results show that directviewing of longitudinal bending, local bending and their superpose phenomena were reappeared by the experiment. Student＇s ability of practice and understanding of knowlege were enhanced and student＇s interestin~ was excitated hv the course.
