【摘要】 基于生命周期理论,对气动执行器与电动执行器的整个生命周期内总的成本费用、总的能耗和总的污染物排放量进行了研究,提出了衡量产品全生命周期成本的一种新的模型;同时给出了基于动态的两个执行器在整个生命周期中总的能耗、总的污染物排放量的计算方法。更多还原

【Abstract】 The paper researched the three-side (cost,energy and contamination) of pneumatic cylinder and electric actuator ,and presented an evaluation method based on the life-cycle theory.After that,according to the dynamic evaluation theory,the theoretical model of the energy and contamination is constructed. So it is beneficial to analysis and select pneumatic cylinder and electric actuator.更多还原
