Program has been developed based on the local analysis method 根據(jù)局部分析法的思路,編制了相應(yīng)的程序。
It takes the global properties of path planning into consideration , and overcomes the shortcoming of 1ocai optimum in some local path planner , e . g . artificial potential field method 這種方法在局部規(guī)劃的同時,兼?zhèn)淞寺窂揭?guī)劃的全局性,有效地從根本上避免了人工勢場法等局部分析方法容易陷入局部最優(yōu)的不足。
In this thesis , a new method named local analysis method was presented which the whole structure is divided into two parts : the upper structure and the lower structure . the problem distribution of initial pre - stress of suspen - dome can solved by this method 提出了基于將上部單層網(wǎng)殼和下部索桿體系兩部分結(jié)構(gòu)分塊的新的分析方法?局部分析法,可以解決弦支穹頂結(jié)構(gòu)的初始預應(yīng)力分布的確定問題。
In the paper , the writer uses various kinds of analysis methods , such as dynamic and static analysis , system and sectional analysis , comparison and integrative analysis , quantitative and qualitative analysis , to demonstrate writer ' s opinions and conclusions systematically 文中綜合運用了動態(tài)分析與靜態(tài)分析、系統(tǒng)分析與局部分析、比較分析與綜合分析、定量分析與定性分析等多種研究方法,全面系統(tǒng)地論證了筆者的觀點和結(jié)論。
We can design the inner force of the upper and under parts and reinforce them according to the results , of which we can pick out the informations about the t hick slab , and analyzes it individualy with finite element methods and calculate its inner force , rainforcing and deformation 把整體分析的結(jié)果,作為厚板轉(zhuǎn)換層上部結(jié)構(gòu)和下部結(jié)構(gòu)構(gòu)件進行內(nèi)力設(shè)計和配筋的依據(jù)。然后利用整體分析中與轉(zhuǎn)換結(jié)構(gòu)有關(guān)的信息,對厚板結(jié)構(gòu)轉(zhuǎn)換層單獨進行有限元的局部分析,求出板的應(yīng)力、內(nèi)力、配筋和變形。
D finite element local analysis is done for hv porcelain post insulator by abaqus finite element software . the stress distribution of one - piece structure under dead weight , erection deviation , temperature change , wind load and short - circuited load is analyzed , which provides the scientific basis for security assessment of post insulator 以高壓瓷瓶支柱絕緣子為研究對象,采用abaqus有限元軟件進行三維有限元局部分析,分析了整體結(jié)構(gòu)在自重、安裝偏差、溫度變化、風載以及短路電流載荷作用下的應(yīng)力分布,為支柱絕緣子的安全性評定提供了科學的依據(jù)。
Lacking of space locality in time domain , fourier analysis can only make certain of the integral singularity of a function or signal . as a result , it is difficult to detect the spatial position and distribution of broken signal by fourier analysis . wavelet analysis has the characteristic of spatial locality , and its wideness in both windows of the time and the frequency can be adjusted , so it can analyze the details of a signal 經(jīng)典的fourier變換把信號按三角正、余弦基展開,將任意函數(shù)表示為具有不同頻率的諧波函數(shù)的線性迭加,能較好地刻劃信號的頻率特性,但它在時空域上無任何分辨,不能作局部分析,這在理論和應(yīng)用上都帶來了許多不便。
