This study has investigated the effect of Young’s modulus variations of the disc brake compo- nents on the squeal propensity using a detailed three dimensional finite element

strain gauges with bending deformations of each elastic beam, but only strain gauges (No. 24-32) on the dual surface of the beams have inertia components coupled into F y output..

Furthermore, the tip displacements at different firing angles were determined by transfer- ring the mass, stiffness and damping matrices of the barrel with the addition of

In this paper two uncertainty approaches were used to evaluate the dynamic responses of a flexible rotor supported by oil film bearings, namely fuzzy and stochastic analyses.. Two

Figure 23 shows the lateral axis transmissibility defined as the relation of the Laplace transforms of the X axis acceleration at the center of moving platform to the transform

In this paper an adaptive fuzzy sliding mode controller is proposed to improve the performance of a pneumatic isolator in the low frequency range, i.e., where the passive

In brief, the new contributions of this paper are: (i) previously unpublished analytical estimates for the effectiveness of the CALM, which support the empirical observation that
