The software design that can be used in all kinds of civil aircraft is a very important work since many kinds of load calculation conditions meeting the requirements of the airworthiness are very complicated 由于适航性要求的载荷计算情况复杂且种类繁多,使得具有广泛适用范围的载荷计算软件的研制成为一项重要的工作。
In this paper the stress-strain and deformation characteristics of loess of the fifth tunnel of luohuiqu were analyzed by means of conventional tri-axial tests and the softening constitutive models were established . the models provide not only the basic and the necessary calculation conditions to analyze the mechanics response and construction optimization of simple shield tunnel method on the fifth tunnel of luohuiqu, but also a new method in researching the softening constitutive models of loess 本文通过对洛惠渠五洞q_1黄土进行常规三轴试验,分析和探讨黄土变形强度特性,建立q1黄土的软化本构模型,这不仅为洛惠渠五洞的简易盾构法施工的力学响应分析及其施工优化提供了最基本,最需要的计算条件,而且为当前土力学研究的热点??土的软化本构模型拓展了新的思路。
The mathematical model is more all-around and the calculation condition is approximate to production condition . the interfhce of the software is fliendly, the data input and modification are convenient and calculating time is short by means of the htc-202 testing eqyipment of nozzle characteristic made in chongqing university, the nozzle cooling state and hot state characteiistic is systematically tested for the 48 kinds of nozzle cmlport and homemade nozzle ) of 1930 caster in bnosteel 针对宝钢1930铸机现用的24种国产喷嘴和同型号进口喷嘴,利用重庆大学研制的htc-202型喷嘴性能测定仪对喷嘴性能进行了系统的测试,得到了3万多个实验数据,对测试结果进行分析,并得到仿真计算所需的边界条件??水流密度和传热系数的表达式。
