缸内压力原始测量信号的处理方法

文章介绍了对缸内采集的原始压力信号的一般处理方法,并比较了不同光顺次数对压力数据的影响,提出了分段光顺的方法。结果表明,通过多循环平均和分段光顺对压力数据进行处理,高压段和低压段均能得到比较光滑的压力曲线,又使处理后的数据与原始测量数据的误差较小。

Method of Dealing with Originally-measured Cylinder Pressure Siginal

This paper has introduced the common method of dealing with originally-measured cylinder pressure signal,compared the resules of the cylinder pressure which were passed different times of smoothing,advanced a method of subsection smoothing.The result indicated that by times without mumber circle averaging and different times of smoothing,not only the high pressure and low pressure of cyclinder pressure became smoother,but also made the error between the result and the orginal data littler comparatively.
