A new method , suitable for identification of distributed loading on continuous model with orthogonal polynomials by using limited measured data is introduced 摘要用正交多項式擬合的方法對連續(xù)系統(tǒng)的分布動態(tài)載荷進行識別的技術,為用有限的測量信息進行連續(xù)系統(tǒng)分布載荷的識別提供了可行的方法。
In addition , this paper also discusses eigenvalue inverse design methods of continuous model of pole and girder , these methods can solve some eigenvalue inverse design problems of simple structures 此外,本文還就桿和梁的連續(xù)模型的特征值逆設計方法進行了闡述,運用這些方法,可以解決很多簡單結構的特征值逆設計問題。
2 . based on continuous model and discrete model of control system , simulation technology is studied , finally curves about water level and journey of ship are drawn and probability of using is calculated 提出了采用演繹法分別建立三峽五級船閘控制系統(tǒng)的連續(xù)模型和離散模型,并進行仿真研究,得到每個閘室的水位變化圖、船只的行程圖以及船閘的利用率等指標。
3 . based on continuous model and discrete model of control system , demo system of five - step ship gate control system is developed by means of visual basic 6 . 0 , which can show ship gate running to the life in the course of nature and at the time of fault 在以上連續(xù)模型與離散模型的基礎上,采用visualbasic6 . 0開發(fā)出三峽五級船閘運行控制系統(tǒng)的仿真演示系統(tǒng),能逼真地演示出船只在正?;蚬收蠒r的過閘情況。
In the present , the models used widely are two kinds : the continuous model . the continuous model is supported by " smearing out " the discrete support along the track . giving a continuous viscoelastic foundation and a continuous layer represent sleepers 目前所使用的計算模型主要分為兩種:一種為連續(xù)型模型:將沿軌道方向的離散支撐連續(xù)化,將枕木模擬為剛體或為有均布質量和剛度的梁,使枕木成為粘彈性地基上的連續(xù)層。
