In recent years, the safety factor method has been used for the design of cfrp wound pressure vessels, which cannot explain the stochasticity and quantify scientifically the uncertain significant factors, has the disadvantages of low ecomony and so on . under these circumstances, the study on reliability of cfrp wound pressure vessels during the winding technology process and inner pressure loading was accomplished in this paper 本研究針對目前cfrp纏繞壓力容器采用安全系數(shù)法設(shè)計不能解決隨機(jī)性問題,對結(jié)構(gòu)功能的重要影響因素沒有科學(xué)量化,經(jīng)濟(jì)性低等弊端,進(jìn)行了cfrp纏繞壓力容器在纏繞工藝過程中和內(nèi)壓作用下的可靠性研究。
The paper improves the velocity's control rules of a first-order microcosmic stochastic traffic cellular automaton model and incorporates it's stochasticity as a deceleration parameter in the construction of the fundamental diagram used by a macroscopic first-order continuum traffic model 摘要本文對微觀一維隨機(jī)元胞自動機(jī)交通流模型的速度控制規(guī)則進(jìn)行了改進(jìn),并將其隨機(jī)特性轉(zhuǎn)化為減速參數(shù)合并到宏觀一階連續(xù)介質(zhì)理論交通流模型中,重新構(gòu)建了反映流量密度的交通流基本圖。
