Bellevilles Distribute Load to Improve Performance and Reliability
Bolted joints often face stress concentration issues due to limited contact area under the bolt head and nut. These stresses can lead to deformation, especially in materials like copper or aluminum alloys which are commonly used in electrical connections. Solon® Belleville Springs address these challenges by distributing stress evenly, reducing the risk of joint deformation and ensuring consistent electrical performance.
Finite element analysis shows that Belleville springs significantly expand the stress distribution area compared to joints with no washers. By spreading stress over a larger area, these springs maintain low electrical resistance at critical interfaces, improving joint reliability. Belleville springs also counteract differential thermal expansion (DTE), common in high-temperature environments, improving overall performance and longevity.
