    摘要:

    考慮到各參數(shù)敏感因子差異大，為了更加客觀地分析多溫冷藏車降溫過程影響參數(shù)的影響程度，采用敏感權(quán)重分析方法，對多溫冷藏車冷凍與冷藏車廂降溫影響參數(shù)進行了敏感度分析。結(jié)果表明：對于冷藏車廂，當(dāng)取δi為100mm，λi為0.0338～0.0438W/(m·K)時，權(quán)重對應(yīng)呈反比關(guān)系，由0.564降至0.477；當(dāng)δi取20～200mm時，權(quán)重對應(yīng)為0.448～0.126；當(dāng)Ff取0.01～0.02m2時，對應(yīng)權(quán)重為0.28～0.113，其它參數(shù)的權(quán)重小到可以忽略；當(dāng)δg、vw、Q0、vf、Ff、λi、δi、β1、H值增加30%時，對應(yīng)的權(quán)重變化率分別為-32%、-36%、-30%、-37%、-34%、-17%、-30%、1%、05%，反之，減小30%時的權(quán)重變化率分別為90%、58%、42%、78%、56%、17%、44%、-1%、0.5%。冷凍與冷藏車廂的權(quán)重變化規(guī)律幾乎相同，當(dāng)vw、Q0、vf、Ff、δg、λi、δi、β2增加30%時，除β2權(quán)重變化率逐漸向正方向增大外，各敏感因子的權(quán)重變化率變化幅度都逐漸向負方向增大，對應(yīng)的權(quán)重變化率分別為-23%、-39%、-35%、-29%、-46%、-19%、-20%、-5%；減小30%時，除β2權(quán)重變化率逐漸向負方向增大外，各敏感因子的權(quán)重變化率都向正方向逐漸增大，vw、Q0、vf、Ff、δg、λi、δi、β2的權(quán)重變化率分別為104%、50%、66%、54%、138%、20%、25%、5%。

    Abstract:

    Considering the sensitive factor of each parameter differences, in order to analyze the effect of influence parameters of multitemperature refrigerator truck on the cooling process, sensitivity analysis method was used to analyze the cooling influence parameters sensitivity of freezing and refrigerated zone for multitemperature refrigerated trucks. The result shows that: for refrigerated zone, when δi is 100mm, λi is 0.0338W/(m·K) to 0.0438W/(m·K), the weights shows an inverse trend which decreases from 0.564 to 0.477; when δi is 20~200mm, the corresponding weight is 0.448~0.126; when Ff is 0.01~0.02m2, the corresponding weights is 0.28~0.113, the heavy weights of other parameters are negligibly small; when δg,vw, Q0, vf,Ff,λi, δi, β1 and H increased by 30%, the corresponding changing rates of weight are -32%,-36%,-30%,-37%,-34%,-17%,-30%,1% and 0.5% respectively. Whereas, when δg, vw, Q0 , vf, Ff, λi, δi, β1 and H decreased by 30%, the corresponding weight changing rates are 90%, 58%, 42%, 78%, 56%, 17%, 44%, -1% and 0.5% respectively. The weight changing rates of the freezing and refrigerated zone are almost the same. When vw, Q0, vf, Ff, δg, λi, δi and β2 increased by 30%, the corresponding weight change rates of all the sensitive factors gradually increases in the negative direction except β2, which increases in the positive direction, the corresponding weight changing rates are -23%,-39%,-35%,-29%,-46%,-19%,-20%,-5%. When vw, Q0, vf, Ff,δg, λi, δi and β2 decreased by 30%, the corresponding weight change rates of all the sensitive factors gradually increases in the positive direction except β2, which increases in the negative direction, the corresponding weight changing rates are 104%, 50%, 66%, 54%, 138%, 20%, 25%, 5%, respectively.
