摘　　要：以ＫＢＭ法为基础，引进谐波平衡观点来研究弹性直杆热膨胀状态下的非线性振动．通过实例计算表明，弹性直杆热膨胀状态下非线性振动的频率对温度的变化非常敏感．The noalinear vibrations of elastic straight column in state of thermal expansion are discussed with Harmonic Balance Technique and KBM method in this paper.The analyses of practical examples indicate that the nonlinear vibration frequencies of elastic column in thermal expansion are very sensitive to the changes of temperature.

关 键 词：弹性直杆 热膨胀 非线性振动 谐波平衡
