摘　　要：用待定系数法给出了一般初值条件下无阻尼两自由度振系对简谐激励的响应，并用坐标变换法证明在一般初值条件下动力吸振器不能完全消除主系统的振动。The response of two-degree-of-freedom undamped systems to harmonic excitations and to general initial conditions is presented by the undetermined coefficient method. The coordinate transformation is applied to demonstrate that dynamic vibration absorbers cannot eliminate vibration of the principal system for general initial conditions.
