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.
