Vibration & Impact Simulation Service

FEM-based dynamic behavior analysis for scientific research materials and structures.

Vibration & Impact Simulation is a core branch of computational structural dynamics, leveraging numerical methods—predominantly the Finite Element Method (FEM)—to replicate, analyze, and predict the dynamic behavior of structures, materials, and components under oscillatory forces (vibrations) and short-duration, high-intensity transient loads (impacts) in scientific research contexts. Unlike physical testing, which is often limited by cost, equipment capacity, and destructiveness, this virtual testing technique constructs a high-fidelity digital twin of research specimens, applies precisely controlled dynamic loads, and solves complex partial differential equations to quantify stress distributions, deformation patterns, natural frequencies, damping ratios, and failure mechanisms. This enables researchers to explore dynamic behaviors that are impractical, dangerous, or impossible to study through physical experiments alone.

Vibration simulation focuses on periodic, non-periodic, or random oscillatory motions that occur over extended timeframes, such as seismic waves acting on civil structures, rotor vibrations in gas turbines, or ambient vibrations affecting micro-electromechanical systems (MEMS). In contrast, impact simulation targets short-duration, high-energy events—typically measured in milliseconds—including drop impacts, explosive blasts, ballistic collisions, or pyroshock events. Together, these two simulation approaches form an indispensable toolset for scientific research, enabling investigators to validate hypotheses, characterize material properties under dynamic conditions, and optimize research designs across disciplines such as materials science, aerospace engineering, civil engineering, and biomechanics.
