ShareFlap-X: investigation of residual stresses and tumbling.
Number: pap.1267
Author(s) : LOF A., MILLWARD C., NAWAZ A.
Summary
Compressive residual stresses are an important influence on the fatigue life of flapper valves in compressor applications. The new material, Flap-X, has optimised residual stresses for a longer fatigue life reed valve. Residual stresses were measured using XRD for various materials before and after tumbling. Hardened strip samples of various thicknesses and steel grades were stamped to produce valve samples. Tumbling trials were performed with different durations. The edge radius and the surface roughness were measured for each thickness to understand if there was any correlation between them. Compressive residual stresses increase with an increase of tumbling time. Residual stresses before and after tumbling of various steel grades vary.
