分析尾轴架的动刚度曲线，可得到尾轴架结构的固有频率。
Analyses of these curves make the natural frequencies of the shaft brackets available.
分析结果表明载荷的变化会对刚度曲线的幅值和周期都产生较大的影响。
The result shows that load has a great effect on the magnitude and cycle time of the stiffness curve.
实现了自动加载、卸载，采样，数据处理，直接绘制、显示和打印刚度曲线等功能。
It automatically loads and unloads, samples, data processes, directly plots, displays and prints the rigidity curve etc.
