Realistic Simulation for the Automotive Industry

Manufacturers and suppliers use Realistic Simulation Solutions from SIMULIA to evaluate design alternatives, collaborate on projects and leverage computing resources for more efficient design analysis.

Brake Systems

Automotive brake systems are complex mechanisms that enable a vehicle to dissipate the energy of motion as heat. Modern brake systems are designed for weight minimization, thermal efficiency and cooling, wear characteristics and noise and vibration characteristics. A successful brake design should be lightweight, durable, wear evenly and consistently and should not suffer from squeal, groan, or other brake noises and shakes. Achieving these numerous goals is a ongoing design challenge.

SIMULIA provides realistic simulation solutions—such as our Abaqus Unified FEA product suite, Multiphysics, simulation automation and optimization capabilities and SLM products—that address a multitude of automotive engineering challenges. The Abaqus Unified FEA product suite from SIMULIA delivers a complete solution for brake design and simulation needs. State-of-the-art contact capabilities, material models, friction material behaviors and loading features provide the user with a unique capability for the simulation of brake system stress for durability, heat generation, temperature distribution and squeal. Our software contains unique functionality for brake simulation including a specialized technique for applying braking torque in the mechanically correct way without the user needing to define force couples for torque application. In addition, a high-performance complex Eigensolver and inclusion of system damping due to frictional contact eliminates the need for complicated DMAP or other programming methodology.
