Structural analysis is performed to check the durability of Engine mounts for a given load and support conditions. The engine mount bracket is subjected to loads primarily due to weight of the powertrain and the unbalanced torque. In this analysis, the component is optimized such that stresses generated do not exceed the endurance strength of the material. In this paper, structural mechanics ...

Sensitivity of a cantilever-mass based fiber Bragg grating (FBG) accelerometer can efficiently be tailored by altering the distance between the axis of the FBG sensor to the neutral axis of the cantilever. To accomplish that in general, a backing patch is used to mount the FBG on the cantilever. Use of finite element analysis to quantify the influence of the material constant (Young’s modulus) ...

Modelling of Pressure Profiles in a High Pressure Chamber using COMSOL Multiphysics
