摘　　要：文章通过对空气弹簧全生命周期成本(life cycle cost,LCC)构成的不确定因素分析,引入盲数理论建立了空气弹簧LCC盲数模型。以某型号空气弹簧为例,使用该模型对其LCC进行估算,得到LCC的估算值区间分布及其可信度,进一步将一组实际数据代入LCC估算模型,验算结果表明该模型合理可行,为空气弹簧LCC估算提供了一种有效的方法。Based on the analysis of the uncertain factors of the whole life cycle cost （LCC） structure of air spring ,the model of LCC of air spring with blind number is established by introducing the blind number theory .Taking a certain type of air spring as an example ,the LCC is estimated by using the model ,and the estimation interval value distribution of LCC and its credibility are gotten .Then a set of real data is utilized in the LCC estimation model . T he results demonstrate the feasibility of the model ,and it can be an effective method for the estimation of LCC of air spring .
