Meshing for NVH, Crash, and Durability in HyperMesh Meshing strategies vary based on the specific simulation requirements for NVH (Noise, Vibration, and Harshness), Crash, and Durability analyses in HyperMesh: 1. NVH Meshing Focused on Acoustics and Vibrations: NVH analysis concentrates on understanding noise and vibration behavior in components or assemblies. Fine Meshing: Requires fine and consistent mesh density near critical areas like joints, connections, or regions prone to vibration. Frequency Considerations: Meshing must account for frequency-dependent behavior, necessitating specific element types and mesh quality for accurate results. 2. Crash Meshing High-Energy Events Simulation: Crash analysis aims to evaluate structural behavior during high-impact events or collisions. Localized High Density: Requires localized high-density meshing at impact points to capture stress concentrations accurately. Element Type Selection: Utilizes specific element types for crash simulations (e.g., solid, shell, or hybrid elements) for efficient energy absorption modeling. 3. Durability Meshing Long-Term Structural Fatigue Analysis: Durability analysis focuses on predicting material fatigue and component lifespan under cyclic loading. Gradual Element Transition: Requires gradual mesh transitions in regions susceptible to stress concentration or fatigue initiation. Element Quality: Emphasizes mesh quality to accurately capture stress gradients and material fatigue.
