ATA Engineering Announces the Release of Vibrata v2.2.0

SAN DIEGO, Calif., October 19, 2018 – ATA is pleased to announce the release of version 2.2.0 of Vibrata. Vibrata is a comprehensive, easy-to-use, advanced dynamics toolkit to predict stress, deflection, and other responses to transient, harmonic, random, and response spectrum excitation. The release brings a number of useful new enhancements to Vibrata.

New Vibrata Features:

One of the most exciting new features in this version update is the incorporation of nonlinear force modeling in the modal transient solver—a capability that is useful for modeling displacement limiting, spring stiffening, and deadband. Two different spring models are supported: one adds stiffness outside prescribed displacement limits and is useful for modeling displacement limiting such as two structures impacting each other, and the other subtracts stiffness, which is useful for modeling deadband in a joint.

Other noteworthy improvements include the ability to export Vibrata XY results to Nastran TABLED1 and TABRND bulk data and the ability to display additional statistics for random analysis results in the XY plotter.
