There appears some flexibility at the top of tower with high ratioofheighttodiameter (H/D), caused by wind load.
高径比（H/D）较大的塔在风载荷的作用下，在塔顶处会引起一定的静挠度。

The distinct characteristic of squeeze casting with larger ratioofheighttodiameter is (heterogenous) distribution of squeeze pressure.
大高径比挤压铸件成形时的一个显著特征是压力沿着轴向分布严重不均。

At last, as the example of squeeze casting with large ratioofheighttodiameter, the temperature field and stress field of high-leg casting were simulated and analyzed.
