农村运输机械的最佳额定载质量研究

Research on the Optimum Rated Carrying-capacity of the Freight Transport Machineries on Contryside Road

本文通过分析农村陆路货物运输作业过程的特点,建立了以农村运输机械基本结构特性参数和运输条件参数为参变量的机械运输作业生产率、各项成本的数学模型。并以此为基础,进一步推出运输机械的最佳额定载量数学模型。应用农村公路运输实测参数进行定量分析表明这些模型能较准确地反映实况。从而为因地制宜地选用农村运输机械提供了方法。这种模型的特征在于有关基本参数容易测取,经过模型计算能较大幅度地提高初级原始数据的信息价值。

By means of analyzing working characters of various freight transport machineries on contryside roads, the paper estabishes math modes of carrying productivity and various costs which vary with parameters of structure and factors for freight transport machinery. From these modes, there is a further inferred one of optimum rated carrying-capacity for the freight transport machinery. By applying to the transport on contryside road, the modes have been proved exact. Therefore, the paper offers the means to choose good freight transport machineries in the light of local conditions. It is in an advantageous position that the original parameters of modes are easy to obtain and can be largely increased in application value by such mode calculation.
