Spring Fatigue

AN INVESTIGATION ON FATIGUE AND FATIGUE CORROSION BEHAVIOR OF Cr-Si SPRING STEEL AFTER Zn-Ni ELECTROPLATING USING WEIBULL STATISTICAL MODEL

Compression springs were prepared from Cr-Si high strength spring steel and coated with pure Zn and ZnNi by electroplating process. The effect of baking after electroplating as well as applying an electroless nickel interlayer on the fatigue and fatigue corrosion of the springs was investigated. The results were analyzed using weibull statistical model. A considerable improvement (8%) in fati...

Monotonic and fatigue testing of spring-bridged freestanding microbeams application for MEMS

An electroplating spring-bridge micro-tensile specimen is fabricated to carry out a series of monotonic tensile testing on it. Freestanding thin films were loaded by performing monotonic loading/unloading and tensiontension fatigue experiments. Loading was applied using a piezoelectric actuator with 0.1 μm resolution connected through pin hole into the test chip specimen. Loads were measured by...

Static And Fatigue Analysis Of Multi Leaf Spring Used In The Suspension System Of LCV

The leaf spring is widely used in automobiles and one of the components of suspension system. It needs to have excellent fatigue life. As a general rule, the leaf spring must be regarded as a safety component as failure could lead to severe accidents. The purpose of this paper is to predict the fatigue life of semi-elliptical steel leaf spring along with analytical stress and deflection calcula...
