本文主要介绍如何应用优化理论来确定塔架的一些参数,以便得到某一最优效果。一、塔架受力分析 1.塔身上的外载荷作用在塔身上的外载荷,经过简化后得到:在顶端有一轴向力P和两个主惯性平面内的弯矩M_x、M_y,塔身正向和侧向的风载q_x、q_y及自重载荷。 2.塔身支承点的简化塔身的侧向支承点看作是弹性支承,其应力变化规律与实测比较接近,因此塔身在侧向载荷(或正向载荷)作用下的计算简图如图1所示。支承的柔度系数可用理论计算的方法求得。计算表明侧向的柔度系数C_y比正向柔度系数C_x大得多。因此也可以把侧向支承看
This article describes how to apply optimization theory to determine some of the tower parameters in order to get some optimal results. First, the tower stress analysis 1. The outer load on the tower body outside the load on the tower, after simplified to get: at the top of an axial force P and two main inertial plane bending moment M_x, M_y, tower Positive and lateral wind load q_x, q_y and self-weight load. 2. Tower body support point of the simplified tower body lateral support point as a flexible support, the stress changes and measured measurements are relatively close, so the tower body under lateral load (or forward load) under the action of the simplified diagram such as Figure 1 shows. The flexibility factor of the support can be calculated by theoretical method. Calculations show that lateral flexibility factor C_y is much larger than forward flexibility factor C_x. So you can also look at the lateral support
