机器效率评价指标系统的分析是机器设计参数和使用性能方案选择的理论基础,也是确定机器技术水平和现有样机技术水平的理论基础。机器的效率是表示机器在给定的使用条件下以最少的耗费高质量的完成所需作业的能力。定量效率评价为机器单位产量的总消耗费用。机器的技术水平为机器和标准样机效率的比值。效率指标的制定应满足下列要求: 指标应能显示所有决定因素——技术参数,生产
The analysis of the machine efficiency evaluation index system is the theoretical basis for the selection of the machine design parameters and the use performance plan, as well as the theoretical basis for determining the machine technology level and the existing prototype technology level. The efficiency of a machine is an indication of the machine’s ability to perform the required job with the least amount of cost and high quality under given conditions of use. Quantitative efficiency is evaluated as the total cost of consumption per machine unit. The technical level of the machine is the ratio of machine and standard prototype efficiency. The formulation of efficiency indicators should meet the following requirements: Indicators should be able to display all determinants - technical parameters, production
