How to Ensure Product Performance and Reliability with Finite Element Analysis? By: Bhaumik Dave – HiTech FEA Finite Element Analysis (FEA) is a technique normally conducted by software to produce models of materials or designs that can then be subjected to virtual stresses. Hence; FEA engineers utilize FEA analysis services to envisage material and product performance under a range of operating conditions, thereby providing real cost benefits over manufacturing and testing prototypes and providing captivating insights into the behavior of the product in this case; we are taking the product as a seal. But the problem is that the model is run with the help of intricate algorithms in a theoretical and unrealistic world where real world testing, expertise and human input is required to bring into life and significantly augment the consistency of the results. Picture-perfect results are not always generated.
A company has industrialized its FEA software using finite element analysis services to provide consistent seal-related modeling on a per application basis. This includes a clear, precise and all-inclusive plan of boundary conditions to be created, by taking into account hardware interaction with the product or whether the seal needs to be stretched or twisted for installation. They have integrated a library of precisely modeled materials, both metallic and non-metallic which is needed to provide results that are as close to real-world scenario as possible. The company performs bulk of its analysis on non-metallic materials which necessitates non-linear modeling. This depends profoundly on the quality of material properties utilized in the model. Consequently all materials need to be comprehensively tested in the real world to determine stressstrain curves, Poisson ratios and all other physical material properties. The precise modeling of the seal before parameters like stresses are used which is principal for a successful analysis.
Once a comprehensive model of the seal has been industrialized, an all-inclusive understanding of the forces and stresses that the product or seal will be subjected to is required. An assortment of operational conditions can be premeditated, for example; a flat or varying temperature and pressure conditions or dynamic movement of the hardware surrounding the seal. Calculating for the countless possibilities can be intricate and should be done on a case-by-case basis, needing human analysis and knowledgeable operators. Whether a 2D or 3D model is selected depends on the application. 2D models are for axi-symmetrical, plan strain and plane stress analysis, which helps in validating how a product will install, grow from thermal expansion and react to forces or pressures applied. Whereas a 3D model offers a more comprehensive picture of a product such as a seal that operates under intricate and often varying stresses, consenting for non-uniform profiles or voids. 3D analysis is required to envisage more intricate profiles enhancing the reliability of the results obtained and for simulating unconventional positions or loads for axi-symmetrical geometries.
How can FEA Help in ensuring product performance and reliability? FEA services can be extremely useful in ensuring maximum product performance; in this example guaranteeing maximum seal life in an application. It also helps in envisaging seal deformation under load, the sealing contact forces or the contact pressure distribution, the latter is particularly valuable for augmenting dynamic seals or to reverse engineer prevailing problems to discover the root causes. This helps in predicting reliability of a product.
