High Cyclic Fatigue Behaviour of Varied Pitch Compression Springs for Automotive Applications

Atkinson, Callum, Naveed, Nida, Haq, Mir Irfan Ul and Ahmad Mehrabi, Hamid (2022) High Cyclic Fatigue Behaviour of Varied Pitch Compression Springs for Automotive Applications. Journal of Robotics and Mechanical Engineering, 1 (1). ISSN 2770-4122

Item Type: Article


In this paper, fatigue life of coil springs was
investigated as failure due to high cyclic loading during
their service life is more common. For this purpose,
two exclusive rear coil compression spring geometries
were investigated using material type - siliconchromium
steel SAE-AISI 9254 for this application. For
these design models, the effect of changing component
geometry using varying pitch arrangements of coils were
examined to understand their structural durability and
ability to withstand cyclic loading conditions. A finite
element model based on industry standard designs
was created to simulate real-life spring performance.
In this study, the varied pitch designs were subjected
to lower stresses in static analysis and have longer life
estimates in the fatigue analysis. This confirms that
a varied pitch can improve the performance of a coil
spring. The result shows that design-1 incorporated a
pitch design that reduced pitch at the centre coils of the
spring performed better.
