Effect of Taper Forms on the Dynamic Response of A Rectangular Cross Section Cantilever Beam

Tapered beams are more effective than uniform because they offer a superior distribution of mass and strength also satisfy unique functional requirements in many engineering applications. This study calculates the mode shapes natural frequencies straight various tapered Euler-Bernoulli by finite elements using ANSYS 16.5 software. The dynamic response for cantilever beam was obtained different taper angles. results were compared with beam, to show effect ratio on when its volume constant. showed that increased as angle increases, torsional shifted from fourth frequency fifth one increases.
