| 摘 要： | 分析了传统发动机外特性模型建立的条件和现有模型的不足,在只有发动机最大功率、最大扭矩及其对应转速等四大参数的情况下,引入最大功率点的附件损失系数,建立了基于四参数的发动机使用外特性模型。结合具体实例分析了该计算模型与拟合模型及试验数据的偏差,运用Matlab程序分析了该理论模型的精确性和工程实用性,最后提出了该模型的使用条件。

| Abstract: | Theoretical model of external characteristic of engine based on four parameters was built after analyzing the establishment condition of traditional engine external characteristic model and the drawbacks of existing models by putting forwardaccessories loss coefficient at maximum powerunder the four parameters.i.e.Max.power,max.torque and relative rotating speed,and so on.Then an example was cited to analyze accuracy and practicability of the theoretical model by Matlab.Finally,service conditions of the mod... |
