摘 要：
考虑到各参数敏感因子差异大,为了更加客观地分析多温冷藏车降温过程影响参数的影响程度,采用敏感权重分析方法,对多温冷藏车冷冻与冷藏车厢降温影响参数进行了敏感度分析。结果表明:对于冷藏车厢,当取δi为100 mm,λi为0.033 8~0.043 8 W/(m·K)时,权重对应呈反比关系,由0.564降至0.477;当δi取20~200 mm时,权重对应为0.448~0.126;当Ff取0.01~0.02 m2时,对应权重为0.28~0.113,其它参数的权重小到可以忽略;当δg、vw、Q0、vf、Ff、λi、δi、β1、H值增加30%时,对应的权重变化率分别为-32%、-36%、-30%、-37%、-34%、-17%、-30%、1%、0.5%,反之,减小30%时的权重变化率分别为90%、58%、42%、78%、56%、17%、44%、-1%、0.5%。冷冻与冷藏车厢的权重变化规律几乎相同,当vw、Q0、vf、Ff、δg、λi、δi、β2增加30%时,除β2权重变化率逐渐向正方向增大外,各敏感因子的权重变化率变化幅度都逐渐向负方向增大,对应的权重变化率分别为-23%、-39%、-35%、-29%、-46%、-19%、-20%、-5%;减小30%时,除β2权重变化率逐渐向负方向增大外,各敏感因子的权重变化率都向正方向逐渐增大,vw、Q0、vf、Ff、δg、λi、δi、β2的权重变化率分别为104%、50%、66%、54%、138%、20%、25%、5%。

摘 要：
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 δiis100 mm,λiis 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 δiis 20 ~ 200 mm,the corresponding weight is 0. 448 ~ 0. 126;when Ffis 0. 01 ~ 0. 02 m2,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,β1and 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,β1and H decreased by 30%,the corresponding weight changing rates are 90%,58%,42%,78%,56%,17%,44%,-1% and0. 5% respectively. The weight changing rates of the freezing and refrigerated zone are almost the same.When vw,Q0,vf,Ff,δg,λi,δiand β2increased 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,δiand β2decreased 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.
