JLR uses a variety of techniques to perform linear and nonlinear dynamic analyses, including both time (transient) and frequency (vibration) based solutions. These include the following:

Modal Analysis - Used to calculate the natural frequencies and mode shapes of a structure. Different mode extraction methods are available.

Harmonic Analysis - Frequency domain solution used to determine the response of a structure to harmonically time-varying loads. Also called vibration analysis.

Transient Dynamic Analysis - Used to determine the response of a structure to arbitrary time-varying loads such as a shock load. All nonlinearities can be used, including contact, nonlinear materials, and large strain.

Spectrum Analysis - An extension of the modal analysis, used to calculate stresses and strains due to a response spectrum (often used in seismic analysis) or a PSD input (random vibrations).

Explicit Dynamics Analysis - Uses the LS-DYNA explicit finite element program to calculate fast solutions for highly nonlinear large deformation dynamics and complex contact problems.
