Assessing Geometry of the Adhesive Pattern for a Brake Shoe Joint to Minimize Mass of the Adhesive

The adhesive joint for the disc brake is the subject of study for this dissertation work. The brake system is expected to endure the shear forces during braking at the operating speed of the vehicle. The adhesive joint is analyzed using computational tool in the CAE domain - HYPERWORKS. The virtual model for the brake shoe joint consist of the base, the liner and the adhesive layer keeping the mating parts in place. Pre-processing for analysis carried out using HYPERMESH while generating suitable mesh and assigning the loads and boundary conditions for the Finite Element Model. The FE model solved using OPTISTRUCT followed by post-processing using HyperView. The geometry or the configuration of the adhesive layer altered to investigate four variants – Horizontal stripes, vertical stripes, inclined strips and criss-cross stripes. The results are reviewed with a plan for experimentation for the suitable variant. Realizing the objective of using minimal adhesive to perform the intended function is the focus of this work. The design parameter for this work has been identified as the `Geometry’ of the adhesive layer. A researcher could consider pursuing future work over `Material’ as a parameter for study. The work has used `Altair HYPERWORKS as a computational tool (solver) while determining the solution. Alternative solvers like ANSYS or NASTRAN could be considered for deployment. A doctoral program might consider theme as `multi-parameter/multi-response optimization’ for the adhesive joint using Statistical Treatment to the experimental data.
