  • Online:2013-06-25 Published:2013-06-20

摘要: 拓展一道基础训练题的内容,对其非线性效应中的“非典型”拍频现象和“突变张力”点进行了研究.就其出现的成因和导致的结果作了初步分析,通过模拟计算阐明原力学模型不够完善的地方.

关键词: 悬棒, 非线性, 拍频, 张力突变

Abstract: We extend a simple exercise in a textbook and find rich physical information by studying nonlinear effect of the system under consideration. The non-typical beat phenomenon and the abrupt change in tension are the most noteworthy results. We analyze these results, investigate the factors that lead to them and point out the drawbacks of the original model through simulating calculations.

Key words: hanging rod, nonlinear, beat frequency, abrupt change in tension
