Perform Sensitivity Analysis
Use a sensitivity analysis to study modal contribution.
The standard post-processing in SnRD can be used to generate time domain displacement plots of each of the node-pairs of all the E-Lines that are present in the model. The purpose of the sensitivity analysis is to study the root cause of rattle and/or squeak at each E-Line.
- Determination of Relative Modal Contribution to squeak and rattle of complete E-Lines and as well as at specific points on each E-Line.
- Capability to check the effect of changing the percentage of modal contribution on the squeak and rattle performance.
- Calculate the relative Modal Contribution of the required E-Line to be analyzed.
- Observe the change in results.
Specifically, when the modal contribution is varied by either including or excluding a certain mode from the result calculations with a modal sensitivity study.
The relative modal contribution for a particular E-Line can be calculated and studied in two ways:- Study the modal contribution of the complete E-Line.
- Study the modal contribution of a particular node pair of an E-Line.
