本文研究了内燃机表面振动信号的特征，指出这些信号是非常复杂的不稳定随机信号，同时具有分形和多分形的特征，并指出内燃机的振动是多维非线性动力学问题。这一基础性研究通过实验得到了证实。对内燃机表面振动信号进行识别是诊断内燃机机械故障状态的关键基础。
The characteristics of the surface vibration signals of the internal combustion engine are studied in this paper.It is demonstrated that these signals are very complex unstable random signals,and in the mean time they have features of the fraction and multi fraction.It is also pointed that the vibration of the interanl combustion engine is the multi dimension non linear dynamic problem.This fundamental study is proved by experiments,and it is the key fundament on which the machine fault conditon of the engine is diagnosed by distinguishing the surface vibration signals of the internal combustion engine.
