EQ1090型货车使用可靠性与技术经济指标变化规律研究

A Study of EQ1090 Truck's Operation Reliability and Variation Laws of Its Technical-economical Indicators

本文对大量实际运行样本数据进行研究,揭示了EQ1090型货车的整车运行故障发生规律,给出了其故障密度函数f(l)、分布函数F(l)、可靠度函数 R(l)和故障率函数λ(l),求取了若干使用可靠性特征量的估计值和观测值。另外,还得出了该型货车若干重要技术经济指标的变化规律。

Based on a large number of sampling data, this paper reveals the statistical law of operational failure's occurrence of EQ1090 truck, with the failure density function f(l), distribution function F(l), reliability function R(l), and failure rate function (l) given. Estimated and observed values of some characteristic measures of operation reliability are calculated. In addition, EQ1090 truck's variation laws of technical-economical indicators are also gives.
