The Use of Pre-Test Analysis Procedures for FE Model/Test Correlation of a Transmission Side Cover

The widespread use of finite element models in assessing system dynamics for NVH evaluation has led to a recognition of the need for improved procedures for correlating models to experimental results. With the greater occurrence of finite element models preceding the first prototype hardware, it is now practical to employ pre-test analysis procedures to guide the execution of the tests in the correlation process. This aids in the efficiency of the test process, ensuring that the test article is neither under nor over instrumented. The test-analysis model (TAM) that results from the pre-test simulation provides a means to compare the test and model both during the test and during the model updating process.

This paper discusses procedures for pre-test analyses and demonstrates their application to the correlation of a transmission side cover.
