借助差分法，建立了具有弹簧支承正交异性层合悬臂板的特征方程。数值上计算了具有弹簧支承０°和４５°玻纤／环氧层合悬臂板的模态参数，给出了固有频率和弹簧系数间的关系曲线以及振形特征。分析了固有频率依赖于弹簧系数的特点。进行了无弹簧支承和２种不同弹簧系数支承的模态试验，测定了固有频率、阻尼比和振形等模态参数。对于前６阶固有频率的测定值和计算值符合得较好。
With the help of the difference method, the eigenvalue equation of a cantilever plate with spring-supported orthotropic laminate was established. The modal parameters of the 0 ° and 45 ° glass fiber / epoxy laminated cantilever plates with spring support were numerically calculated. The relationship between the natural frequency and the spring constant and the vibration characteristics were given. The natural frequency depends on the characteristics of the spring coefficient. Modal tests without spring support and two kinds of springs with different spring constants were carried out. Modal parameters such as natural frequency, damping ratio and vibration shape were measured. For the first 6 natural frequencies measured values and calculated values in line with better.
