摘要:

在机械性能和工况相近的情况下,对3组气动执行器和电动执行器进行生命周期评价(LCA,Life Cycle Assessment),分析了气动和电动执行器的环境影响评价主要因素,确定了两种执行器的LCA研究范围、系统边界和时间边界,归纳了两种执行器制造过程的主要工艺和零部件的工艺特征,最后在Simapro 7.1中进行了两种执行器的评价框架建立和数据录入,根据Eco-indicator 99进行了两种执行器LCA对比分析.结果表明,执行器对资源的环境影响约占环境影响综合值的50%;机械性能和工况相近的气动和电动执行器,电动执行器的环境影响比气动执行器大.

关键词: 气动执行器, 电动执行器, 制造工艺, 环境影响评价, 生命周期评价

Abstract:

In the similar mechanical performance and working condition cases,life cycle assessment (LCA) of three groups of pneumatic actuators and electric actuators was carried on in order to analyze the extent of environmental impact of the actuators. The main environmental impact assessment factors of pneumatic actuators and electric actuators were analyzed. And the scope of the study, system boundaries and time boundaries were determined for the LCA of two kinds of actuators. The main manufacturing process and components processing features of two kinds of actuators were summed up. Finally the evaluation framework establishment and data entry of two kinds of actuators were conducted with Simapro 7.1, and the LCA comparative analysis of two kinds of actuators was carried out with Eco-indicator 99. The result reveals that the resources impact accounts for about 50% of the overall environmental impact value of actuators, and the environmental impact of electric actuators is large than that of pneumatic actuators under the similar mechanical properties and working conditions of these actuators.

Key words: pneumatic actuator, electric actuator, manufacturing process, environment impact assessment, life cycle assessment
