Dynamic structural simulation
Environmental specifications nearly always include shock load, half sine wave or saw tooth profile, and forced vibration which may be sinusoidal or random. Typically equipment must operate at a low level and survive a higher level.
A key strength of Linear and Non-Linear Dynamic studies is to simulate environmental conditions such as shock, vibration (sinusoidal and random), drop test and impact.
Forced Vibrations: - predict and control vibrations or dynamic responses with a choice of Transient, Harmonic Response, and Random Response studies.
Sinusoidal
vibration
Random
vibration
Random vibration expressed as a Power Spectral Density (g^2/Hz), will give rms response values i.e. 68.26% probability they will not exceed result. (95.45% = 2 x result value and 99.73% = 3 x result value)
Shock Load Simulation, Drop Test or Impact. Half-sine or saw-tooth accelerations, realistic collision simulation between parts or assemblies.
Shock pulse
Other Nonlinear dynamic capabilities, include: nonlinear displacement analysis, nonlinear buckling analysis, analysis of nonlinear materials, as well as dynamic response analysis of parts and assemblies.
We can produce physics based assembly simulations that model friction, inertia, mass and non-linear spring / damper systems.
