前言本文是讨论通用汽车公司研究试验室用于发展高功率发动机零部件所采用的技术和设备,通常用实物原寸的发动机零件作试验,并且无论在何种情况下均需将热负荷叠加在机械负荷上以获得尽可能真实的运用条件。这里所讨论的试验设备是通用汽车公司为此目的而特别设计和发展的。这些零件在实际使用中受到 Preface This article discusses techniques and equipment used by General Motors research labs to develop high-power engine components that are typically tested in-kind in-line engine parts and superimposed on heat in machinery Load to get as realistic as possible conditions of use. The test equipment discussed here was specifically designed and developed by General Motors for this purpose. These parts are actually used
