| 摘 要： | 谐振增压系统中的进气压力波与小振幅波类似,用力学—声学类比方法对谐振增压进行了物理原理的研究,证明了系统的力学品质因素对谐振曲线的形态有重要影响.文中考察了系统各尺寸之间的关系及对压力波初相位的牵制,提出了调整压力波幅值与初相位角的途径.在谐振转速点上肯定得不到最高充气效率,本文给出了缩小两者间差距的有效方法.试验结果证明了理论分析中的结论.

| Abstract: | The inlet wave in a resonant system is similar to the small ampli
-tude wave.By means of the mechanics-acoustics analogy method,the
physical principles of resonant supercharging are studied.It has been proved
that the system's quality factor has an important influence on the shape of
the resonance curve.This paper observes the relationship between the sizes
of the system and the initial phase of the pressure wave,and then the theory
of adjusting the pressure wave's amplitude and initial phase is proposed.
At the point of resonant speed the highest volumetrc efficiency cannot be
obtained but the method for shortenning their gaps is described.The
results of the experiment have justified the conclusion of the theoretical
analyses. |
