摘要: 分析了气动执行器和电动执行器能量消耗过程,建立了气动执行器运行能耗计算模型,搭建了气动执行器和电动执行器的运行能耗实验系统.通过实验数据分析,得出两种执行器运行能耗的结论:①在长时间保持负载或作动不频繁的工况下,气动执行器比电动执行器更节能,在频繁作动的工况下,电动执行器比气动执行器更节能;②在各种工况下,气动执行器的运行功率波动不大,电动执行器的运行功率波动较大.

Abstract: The energy consumption processes of pneumatic actuator and electrical actuator were analyzed. A calculation model of the energy consumption for pneumatic actuators was proposed. And two sets of actuators experimental system for pneumatic actuator and electrical actuator were built up. The large quantities of the experimental data were received from the energy consumption experiments of two types of actuator. The main results were gained through the analysis experimental data :①The pneumatic actuator is more energy-efficient than the electrical actuator on the condition of maintaining the load for a long time or the condition of unfrequent actuation. However, the electrical actuator is more energyefficient than the pneumatic actuator on the condition of frequent actuation. ②In a variety of operating conditions, the running power of the pneumatic actuator fluctuates slightly and the running power of the electric actuator has a great fluctuation.
