to forecast the SnR issues in the systems based on the manufacturing variations like,
component thickness, attachment stiffness, modal damping and etc.
The manufacturing of a parts is often related to variations of tolerances and quality of
materials. In addition, the assembly process adds a set of variations on dimensions and
stiffness of connections, resulting in a unique product at each build. These two major
processes affect the product final quality and therefore its performance.
Squeak and Rattle are phenomena that are tightly related to the quality of the built
parts, and performance can vary through the population of produced products.
The Manufacturing Variations Study workflow will take you through
the steps of setting up a variation study to analyze the risk and effect of the
manufacturing problems. Below is an illustration for Manufacturing Variations
Study.
Note: SnRD requires a runnable solver model, which should either
contain a Dynamic or Static Loadcase.
This is required since HyperStudy works on the principle of a
comparing results of a nominal run with the consecutive run results.
