“倒拖法”求上止点在ZTY265天然气压缩机动态压力测试系统中的应用

Application of Motoring Test Method for Determining TDC to Dynamic Pressure Trial System of ZTY265 Natural Gas Compressor Set

在进行内燃机燃烧分析时,上止点相位对分析结果影响很大,正确确定内燃机动态上止点相位显得非常重要。本文详细介绍了用"倒拖法"确定内燃机动态上止点的方法及具体过程,设计了其计算机算法,并在ZTY265天然气压缩机动态压力测试系统中加以应用,得到了较精确的结果。

The top dead center (TDC) phase has a great effect on the result in the combustion analysis of internal combustion engines, so it is very important to obtain the dynamic TDC phase correctly. The method and process for calculating dynamic TDC phase with the motoring test mestod are introduced in detail. Their computer algorithm is designed and applied to the dynamic pressure trial system of ZTY265 natural gas compressor set with the precise results.
