Vibrations tutorials: free and forced vibration, damping, natural frequency and resonance for engineering students.
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)….
What Is Vehicle Roll? Vehicle roll is the rotation of a car’s body around its longitudinal (front-to-rear) axis as it goes through a corner. It’s measured as the roll angle — the tilt between the vehicle body and the road — and it happens because lateral (sideways) forces act on the vehicle’s center of gravity…
What Is Ride Quality (Ride Comfort)? Ride quality, also called ride comfort, describes how well a vehicle isolates its occupants from road-induced motion and vibration. A vehicle with good ride quality protects passengers from bumps, potholes, and rough pavement, reduces driver fatigue on long trips, and helps prevent damage to cargo. Ride quality is shaped…
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…
