原则上讲,这个是应该保密的,但是由于斑竹的热心帮助和便于活跃本版的学术气氛,我不能什么也不说。我是在分析一个梁的动力学稳定性,对梁的transverse motion 建立的运动方程,是一个可以看作mathieu 方程的方程 ...

We review crane models available in the literature, classify them, and discuss their applications and limitations. A generalized formulation of the most widely used crane model is analyzed using the method of multiple scales. We also review crane control strategies in the literature, classify them, and discuss their applications and limitations. In conclusion, we recommend appropriate models and control criteria for various crane applications and suggest directions for further work.
Key Words: Crane • dynamics • control • stability • gantry crane • rotary crane • boom crane |
