Reduce vibration and noise within your design constraints
LaFontaine Engineering supports early-stage and detailed design to reduce dynamic loads, noise levels, and performance risk. We address sources and transmission paths while keeping mass, packaging, thermal, alignment, and launch-load constraints in view.
Inputs we work with
Disturbance sources, transmission paths, sensitive equipment, structural and vibroacoustic models, installation requirements, and available test data. Finite element and vibroacoustic analyses assess stiffness, modal characteristics, damping, and coupling mechanisms.
Design trades and deliverables
• Structural tailoring to separate modal frequencies, improve load paths, and reduce dynamic amplification
• Passive damping treatments selected for the relevant response mechanisms
• Acoustic barriers, liners, and absorptive treatments assessed for material properties, installation constraints, and frequency-dependent performance
• Elastomeric, viscoelastic, and multi-axis isolation concepts with stiffness and damping selected for attenuation, structural integrity, and alignment
• Trade studies balancing isolation performance against mass, envelope, thermal, and launch-load constraints
Verification and test correlation
Mitigation concepts are assessed for testability and compatibility with sine, random-vibration, and acoustic qualification environments. Where measurements are available, predictions are correlated to test data to support verification and flight-readiness decisions.
