This research presented a numerical assessment for a a selected theoretical design of single and stacked Belleville spring taken into consideration the strength behaviour. Theoretical and numerical analysis focused on two main factors which are the spring force and the variation of the stress at a specific locations across the spring section related to the deflection. This research chose the spring design dimensions according to the Belleville spring standard. The numerical simulation are done by employing ANSYS APDL 2018 software based on the same design and selected material properties. The comparison between the finding shows a good match with deviation less about, where the variation for a single spring being less than 10.9%, and the deviations being about 11.8% and 12.8% for two and three parallelly stacked discs. On the other hand, the divergence was approximately 12.4% and 12.2% for two and three discs stacked in series. The stress distribution results across the spring section shows at the final deflection of (1.15 mm), the maximum von Mises stress is concentrated at the upper surface of the inner hole of the spring, this stress is reduced in value when goes deeply through the thickness of the disc, till reach the minimum value at the middle section of the thickness. |
