从理论上对气缸盖振动建立分析模型，再通过时域上的逆系统分析求解出气缸内压力波动情况，并进行了实验验证，为进一步简便测定燃烧压力提供了新的途径。
Analytical model of cylinder head vibration is theoretically established, then the pressure fluctuation in the cylinder is solved by inverse system analysis in the time domain, and experimental verification is carried out, which provides a new way for further simple and easy measurement of combustion pressure.
