With the help of the electronic computers, engineers employ it to figure out nearly all kinds of engineering problems ranging from astronavigation, construction, waterpower projects, ship - building and mechanical engineering etc. owing to the strong power of finite element method, one kind of software pack which based on the method is exploited and named algor feas to resolve problems on structure analysis for trusses and shells. this paper also employ algor feas software pack to analyze and compute the cableway towers, giving the accurate result on stress and displacement both in location and whole. finally, we also bring out some advice on structure improving
在此分析過程中:首先將物理模型簡化為力學模型,主要是將塔架結構按空間桿單元簡化為空間桁架結構,目的是將力學模型變換為數學模型;這一過程主要是利用autocad2000建立塔架的計算模型;再者,利用algorfeas軟體包讀入autocad建立的塔架計算模型生成初始數據卡利用計算機進行編程進行風載計算,再將計算結論整

By using this method, we could make the extended testin and controling system to satisfy the real - time requriement of application. this article is based on the research of " the helicopter ' s aviating load - data harmonized loading and sampling technology ". we studied the question of real - time in the helicopter ' s aviating load - data sampling system, and finally realized the real - time extension of the system which based on windows2000 to improve the real - time performance of the system

The composites not only show excellent photo - responsive properties in the visible and near - ir region ( 450 ~ 850 nm ), but also show complementary and synergetic enhancement effects in photosensitivity in the visible and near - ir region. the reasons for the enhanced photoconductive properties and new effects are explained in terms of the partial and directional charge transfer from phthalocyanine to azo compound in these azo / tiopc composites. 2
