摘要
本文对摆盘式发动机原理样机的热车台架试验的振动信号进行了检测和分析,得到了许多摆盘机的振动特征,与一般的曲柄连杆式发动机相比,它们之间存在着很大的差异。由于这次试验是国内首次,对今后进一步研究和探讨摆盘机及对它的减振降噪都具有重要的意义。
In this paper, it is pointed that wobble plate engine is different from usual engines in the vibration characteristics by measuring and analysizing the vibration signal of desk test. Because this test is first in our country, it is greatly significant for further researching and controlling vibration and noise of wobble plate engine.
