In this paper the ccebc is applied in the analysis of one - mass - spring system and the switches between the left and right centers in the lorenz strange attractor . quantitative indices are introduced and good results are got from sensitivity analyzing 本文先后將ccebc用于分析單彈簧系統(tǒng)的有界穩(wěn)定性及類lorenz系統(tǒng)圍繞左右兩個中心的切換,引入量化指標,并進行靈敏度分析,得到了良好的結(jié)果。
By use of the techniques of operational research , probability and statistics , and via the combination of qualitative analysis with qualitative analysis , an optinun design of production plan was worked out the model of linear programming has been formulated in this connection , the optimal combination scheme of the product structure and output was obtained via the use of computers , the sensitivity analysis was performed and the results were optimized as well the comprehensive production plan was then worked out simultaneously , the optimal economical lot size of production was extracted from the mode of complete - set products 并應用運籌學、概率統(tǒng)計學等方法,通過定性分析與定量分析相結(jié)合,對企業(yè)生產(chǎn)計劃進行優(yōu)化設計,為此,建立了線性規(guī)劃模型,通過計算機求得產(chǎn)品結(jié)構(gòu)及產(chǎn)量的優(yōu)化組合方案,并進行靈敏度分析,優(yōu)化結(jié)果,從而制定出綜合生產(chǎn)計劃。同時提出主生產(chǎn)計劃優(yōu)化方案,利用產(chǎn)品配套模型,求得最優(yōu)經(jīng)濟生產(chǎn)批量。
By this way the model can approach the practical instance . through comparing the road experiments with the result of simulation the corresponding vehicle kinematics model that was bulit by adams was confirmed to be reliable ; this article adequately utilize the trait of adams to do a lot of suspension kinematics simulation calculation and deal with the sensitivity degree to acquire the affect rule of these parameters 運用adams軟件建立與實際懸架系統(tǒng)相對應的整車動力學模型,通過道路試驗與仿真結(jié)果的對比,驗證了模型的可信性;充分利用adams軟件的特點,通過改變懸架有關參數(shù),進行大量的懸架動力學仿真計算,并進行靈敏度分析,最后得出這些參數(shù)對平順性的影響規(guī)律。
