This dataset contains experimental data acquired from the benchmark system of the Tribomechadynamics Research Challenge [1]. The tests were part of Project 3 of the Tribomechadynamics Research Camp 2022 in Stuttgart [2]. CAD models, technical drawings and design documentation are available in [4].

Data obtained by linear modal testing is available, along with data obtained by three types of nonlinear tests, Phase Resonance Testing (PRT), Response Controlled Testing (RCT), and Excitation Controlled Testing (ECT). The test methods are described in [3].

Velocity data was acquired using a multi-point vibrometer (MPV). The 17 sensor locations are indicated in Figure 3 in [3]. Single-point/differential vibrometers (SPVs) were used for feedback control during the nonlinear tests. The SPV data is redundant with the MPV data, and is thus not contained in this dataset.

The naming and the content of each data file type is described in the file “README”.
