Detection methods for residual stress of assembled camshaft

[摘要] Compared with the traditional integrated camshaft, the assembled camshaft has the advantages of lowering production cost, reducing engine weight and improving engine performance, with a broad development prospect. The assembled camshaft is connected by different processes will cause residual stress which will seriously affect the mechanical properties of camshaft. Therefore, the measurement of residual stress is of great importance to the safety and reliability of assembled camshaft. This paper mainly introduces three detection methods currently applied to the residual stress of the assembled camshaft, namely X-ray diffraction method, Hole-Drilling method and Finite element simulation.
