3 多用途工作机构筑路机械的效益指标多用途工作机构机械的效益可以根据表1中所列的指标体系确定.在计算单位产量费用以及2、3、4、5、6、7、8级水平指标时,必须考虑作业种类和使用条件(土的类型,含水量等)出现的概率.多用途工作机构机械效益的初步评价可以在综合指标 Q_(NGn)分析的基础上实现.多用途机械的效益是在与单用途机组联合完成相同种类作业指标的比较之下确定的,其综合效益指标具有如下形式:
3 multipurpose work machine road construction machinery efficiency index multipurpose work machine mechanical benefits can be based on the index system listed in table 1. In the calculation of unit production costs and 2,3,4,5,6,7,8 level Horizontal indicators must take into account the probability of occurrence of job types and conditions of use (type of soil, water content, etc.) A preliminary assessment of the mechanical benefits of a multi-purpose work organization can be achieved on the basis of a comprehensive Q_ (NGn) analysis Multipurpose Machinery The benefit is determined in comparison with the single type of unit to complete the same type of operation indicators, the comprehensive efficiency indicators have the following form:
