Addressing noise in engine design is a complicated science and elusive art. There are many causes of noise and vibration in the engine and many evolving techniques for designing a quiet, pleasant sounding engine. Southwest Research Institute (SwRI) maintains a comprehensive capability for source and signal analysis, model simulations, and structural dynamics.
SwRI has extensive experience in noise control evaluations of numerous gas and diesel powered vehicles. Our engineers evaluate pass-by or operator noise levels in order to formulate experimental programs that will lead to identification of the noise sources, the paths of propagation and acceptable control measures.
Noise Assessment
SwRI facilities include electrodynamic shakers for testing of vehicle components in a prescribed, harsh vibration environment for failure and fatigue assessment. Portable data acquisition systems are also available for vehicle and component vibration analysis and benchmarking.
Vibration Evaluation
Material and Component AnalysisThe SwRI Materials Engineering Department, composed of about 55 staff members including approximately 30 scientists and engineers, has both a broad and deep scope. Unifying themes are life enhancement and lifetime assessment of engineered structures and components.
The Materials Chemistry Section focuses on solving client materials problems through bulk and surface modification, process enhancement, failure analyses and microstructural assessment, and new material development, coupled with specialized testing, characterization, and design of materials.
The Materials Integrity Section performs research and development in the deformation, damage, and fracture of engineering materials with a special emphasis on the integrity of engineering components and structures.
The Mechanics and Materials Section focuses on structural integrity and reliability assessments. These assessments are achieved through combined experimental-analytical/numerical approaches designed to characterize the fundamental mechanical behavior of materials to predict their performance and risk of failure.
At SwRI, we are always striving to offer the best services possible to our clients. This motorcycle technology information represents only a small portion of how SwRI can assist your company with motorcycle testing, research, and development.
