Fuzzy Boundary for Beams Vibrations in Vehicles

ABSTRACT This work aims to study the transversal motion of a car’s chassis, modeled by a beam and supported at its ends by two sets of spring-damper elements. A finite differences method is utilized along with Robin boundary conditions to solve the mathematical modeling. The constants of the boundary conditions are modeled by a fuzzy parameter obtained through a Fuzzy Rule-Based System (FRBS) acting on the different vibrations of the model, depending on the number of spirals and time of use of the spring. The contributions of this study is based on considering the spring’s elastic constant...
