摘要: 分析了气动执行器的能耗特点,结合空气消耗量和比能量概念,提出了一种气动执行器的能耗计算方法.为解决公用气动设备的购置成本划分问题,提出了一种用气设备成本均分法.结合生命周期成本的概念,建立了气动执行器基于用户的全生命周期成本模型(LCCBOU,Life-Cycle Costing Based On Users),进行了实例验证.该模型不仅适用于气动执行器的全生命周期成本分析,也适用于其它用气设备的成本分析.结果表明:用气设备成本均分法实现了气动系统成本的合理划分;气动执行器的LCCBOU模型通过了实例验证,并发现通过空压机的实时监控和气动系统的泄漏测量,LCCBOU模型结果能够做到更精确.

Abstract: Combined with the concept of air consumption and specific energy, and analyzed the energy consumption of pneumatic actuator, a power consumption calculation method of pneumatic actuator was proposed. In order to solve purchasing cost allocation problem of public pneumatic devices, a novel air equipment costs average method (AECAM) was put forward. A new analysis model of entire life-cycle costing based on the users (LCCBOU) of pneumatic actuator was established with the concept and thinking of LCC. A case study validates the model. This model was not only suitable for the entire life cycle cost analysis of pneumatic actuator, is also suitable for cost analysis of other pneumatic equipments. The AECAM achieves a rational division of pneumatic systems costs. LCCBOU model of pneumatic actuator has passed through the case validation, and a new fact is found that the model results can be more accurate, more realistic by real-time monitor of air compressors and pneumatic system leakage measurement.
