摘要
采用ANSYS软件的三种模态计算方法分析了一种辐条式预应力摩天轮的固有频率和模态,指出了重力和拉索的非线性作用对模态特性影响不可忽略,且考虑拉索非线性得到的模态振型的趋势和不考虑时的模态特性趋势相反。
This paper,taking three calculation methods of the software ANSYS,analyses the natural frequency and mode of a pre-stressed spoked ferris wheel.As a result,we prove that the influence can not be ignored of gravity and inhaul cable's non-linear effect to modal characteristics.What's more,taking inhaul cable’s non-linearity into consideration or not has opposite tendency of modal characteristics.
