ESTECH.RIDE

Feature

• The software performs frequency response analysis including nonlinear characteristics together with MSC Nastran by adding frequency and/or amplitude dependency to scalar spring element (CELAS) and viscous damping element (CDAMP) in FE model.
• In the case of frequency response analysis of a system model equipping with scalar element which is hard to neglect nonlinear characteristics such as hydraulic rubber mount as well as shock absorber, the analysis including nonlinear characteristics of frequency and/or amplitude dependency generates much more accurate output comparing with the ordinary analysis results using constant approximate parameters for mount rubber dynamic stiffness and loss factor at specific frequency and amplitude only.
• Mechanism analysis is performed easily with analysis function of the software, which analyzes the output such as forced excitation modes, energy, and element force. As a modal analysis, mode deactivating analysis is available.
