讨论了两自由度系统两种不同的求解固有频率与主振型的方法，为限制或利用机械振动提供重要参考．当要限制振动时，外部激励的频率应尽量远离系统的固有频率以限制系统的机械振动，当利用振动时，外部激励的频率应与固有频率接近或相等以有效利用机械振动．

Two mainly different computational method of solveing natural frequency and main vibration model with two degree of freedom system is discussed. These two methods provide important reference for limiting or utilizing me chanical Vibration. When limiting the mechanical vibration is needed, the externat fregueney of excitation should be kept awary as far as possible from natural frequency of system. On the contrary, the external frequency of excitation should be as approximate or equal as possible to natural frequency of system when utilizing mechanical vibration of system is needed.
