含有随机参数的摩托车排气污染物工况法检测技术研究

Analysis on Testing Results of the Emissions of Pollutants from Motorcycles under Running Mode with Stochastic Parameters

摩托车排气污染物工况法检测结果受到环境温度、相对湿度等多种因素的影响,这些因素存在着很大的随机统计性,使得工况法检测结果存在一致性差的问题。利用现有工况法测试程序,采用Matlab语言分别编制Monte Carlo求解程序和正交响应面法求解程序,建立了工况法排气污染物随机分析模块。最后的案例表明了所论方法的有效性。

Emission test result from motorcycles under running mode is affected by many factors such as temperature and humidity[1]. These factors are random[2] which may induce the problem of poor consistency. With help of the test program of running mode, the model of solving the random problem is built by the Matlab programming language, which is used for the solving programs of Monte Carlo Method and Orthogonal Design-response surface method. The case in this paper shows the feasibility of the method.
