Executive Summary Buzz, Squeak, and Rattle (BSR) refers to unwanted interior and structural noises generated by component interactions inside a vehicle. BSR engineering is a critical part of automotive NVH (Noise, Vibration, and Harshness) development because these noises strongly influence customer perception of vehicle quality, refinement, and durability. Buzz, squeak, and rattle—collectively known as BSR—are…
Objective To measure the natural frequency of a vibrating cantilever beam with different lengths using different sampling rates. Known & Assumptions: Materials: The materials required: Thin aluminum beam Piezo-electric sensor Computer with labVIEW Clamp with steel plates Calipers Procedures: To begin measure the overall dimension of the cantilever beam using the calipers (width and thickness)….
Analysis: The purpose of this project was to simplify and models a 12-story building as a simple cantilever beam. The building consisted of 12 equal rigid floors. The mass of the floors was a known to be 5000 kg. Each of the floors is connected to one another with 4 I-beams. The I beams had…
This simulation is of a vehicle performing a cornering maneuver. During a cornering maneuver, the rolling motion or roll angle which is felt in the vehicle about the x-axis is a result of the inertial forces acting on the vehicle’s center of gravity and the vertical elasticity of the suspension. The roll axis is the…
Introduction: The purpose of this simulation is to model an automotive suspension and the effect it has on overall vehicle ride quality and comfort. Suspension systems must compromise between ride quality and vehicle handling, depending on the goals of the vehicle being designed. Sports cars have suspension systems that are designed for better handling by…
Introduction: The purpose of this simulation is to model an instance when an automotive suspension is bottomed out. When a suspension system bottom outs, the springs has fully compressed and reached its maximum travel–causing the shock to crash into the bump stop. This can happen when a driver impacts a pothole at a high speed…
