摘要
经济寿命的计算通常包括静态和动态2种模式。以某大型露天矿山1999年投入使用的7辆154t630E型矿用电动轮汽车为研究对象,建立电动轮汽车劣化值模型,采用多种经济寿命计算方法,得出电动轮汽车经济寿命为11a,为国内矿用电动轮汽车经济寿命评价提供依据。
The calculation of economic life generally includes static and dynamic types. With the seven 154t 630E mine electric wheel trucks put into use in 1999 in a large open-pit mine as the object of research, a deterioration value model of electric wheel model is established and several calculation methods of economic life are used. The economic life of the electric wheel trucks is found to be 11 years, providing a basis for evaluating the economic life of domestic mine-use electric wheel trucks.
