  • Online:2005-09-25 Published:2005-09-20

摘要: 将作者在<大学物理>2004年第12期上的一篇文章的解法推广到弹性杆的强迫纵振动问题,并求解了两端系有集中质量的弹性杆的自由纵振动问题.

关键词: 弹性杆, 强迫振动, 齐次边界条件, 集中质量, Laplace变换

Abstract: We have extended the method used in our one end attached to a concentrated mass and another paper to the case of forced vibra.tion of an elastic rod end subject to a homogeneous boundary condition. We have also discussed free vibration of an elastic rod with two ends attached to concentrated mass.

Key words: elastic rod, forced vibration, homogeneous boundary condition, concentrated mass, Laplace transformation
