Parametric Simulations of the BARC Model in SDOF and MIMO Configurations for Estimating Service EnvARC) model are simulated with implicit and explicit methods using the commercial FEA tool ABAQUS, where the multiple observed outputs are vibrational responses in the three translational degrees of freedom. The model looks to validate physically obtained experimental data by replicating certain boundary conditions and service environments.取消 发表于 2025-3-27 01:09:30
Test Data Measurement Uncertainty Analysis,ent programs. Calculating and documenting test data uncertainty is a necessary capability for a test organization. Test data uncertainty analysis provides error limit values based on the combined effects of random and systematic error sources. Error source examination can also be used to determine i话 发表于 2025-3-27 07:55:49
Forced Vibrations of Damped Non-homogeneous Timoshenko Beams,f a two-segment damped Timoshenko beam. In the series, frequency response functions (FRFs) were determined for segmented structures, such as rods and beams, using analytic and numerical approaches. These structures are composed of stacked cells, which are made of different materials and may have dif吼叫 发表于 2025-3-27 11:15:28
Parametric Simulations of the BARC Model in SDOF and MIMO Configurations for Estimating Service Envnet response of multiple single-axis vibration tests results in an overestimation of the severity of the service environment. In practice, over-testing has been a result of the limitations associated with physical experimentation, which indicates a need to improve simulation methods and accuracy ofANNUL 发表于 2025-3-27 17:22:53
Experimental Modal Analysis of a Resonant Plate During a Mid-Field Pyroshock Replication Test, mid-field pyroshock for component qualification. Since that time, many high severity shocks have been specified that take considerable time and expertise to setup and validate. To aid in test setup and to verify the shock test is providing the intended shock loading, it is useful to visualize the r嘲笑 发表于 2025-3-27 21:23:45
A Parameter Study of the Matrix Power Control Algorithm,nt(s) in the laboratory in such a way as to mimic their real-world environment. This is particularly useful when testing a component in its real-world environment is time-consuming or costly. To accurately control, a random vibration test is not a simple challenge to meet, with issues arising such a折磨 发表于 2025-3-27 23:53:41

Techniques for Modifying MIMO Random Vibration Specifications,ecent years, research into specifications for these types of tests has not kept pace. This is perhaps due to the very particular requirement for most MIMO random vibration control specifications – they must be narrowband, fully populated cross-power spectral density matrices. This requirement puts coptic-nerve 发表于 2025-3-28 06:44:29
On the Selection of Mode Shapes Used in Optimal Sensor Placement, and assure their serviceability and safety throughout their service life. To assure reliable SHM systems, optimal sensor placement (OSP) is a cornerstone since it directly influences the quality of obtained data and, thus, the accuracy of the diagnosis. Hence, determining the optimal sensor configuArteriography 发表于 2025-3-28 12:49:30
