一、问题的提出无论是活塞式发动机,还是活塞式压缩机,活塞环是关键零件,它直接影响产品的性能与可靠性。而活塞环径向弹力与开口间隙关系式在设计上、质量检验上是很重要的。此式在一般书籍上都没有推导过程。笔者用能量法计算变形的方法,推导出这一公式,在推导过程中,尤感此法简捷,通过实际测量,证明此式在工程上已足够精确。现将公式推导向读者介绍,以求指教。
First, the issue put forward Whether it is piston engine, or piston compressor, piston ring is the key components, it directly affects the performance and reliability of the product. The piston ring radial elasticity and opening gap relationship in the design, quality inspection is very important. This type of general books are not derived process. The author uses the energy method to calculate the deformation method, deduces this formula, in the derivation process, especially this method is simple, through the actual measurement, this type of program has been accurate enough. The formula is now introduced to readers, in order to advise.
