Determining a damping coefficient by using a microelectromechanical systems accelerometer for finite element method simulation purposes on a discrete damper example

The paper presents a fast method for determining the damping coefficient using a microelectromechanical systems (MEMS) accelerometer, demonstrated on the example of a discrete damper element used in FEM simulations.The primary focus is on addressing a critical gap in current FEM modelling -damping is traditionally expressed as a percentage without a direct physical correlation in SI units.Additionally, there is a lack of efficient methods for quickly estimating damping in equipment that can be modelled as discrete elements.A methodology is designed specifically for one-dimensional discrete elements such as springs and dampers in FEM simulations.A key advantage of this approach is its reliance on simple, readily available measurement equipment, allowing for easy reproducibility of results without the need for complex laboratory apparatus, where repeatability is often difficult or impossible to achieve outside the laboratory, whereas the presented method offers such capabilities.
