Data can be moved into in a frequencyamplitude table, taking treatment to employ the appropriate systems and scale aspect.Additional Sources: ANSYS Software ANSYS Education Courses Occasions Webinars ANSYS Consulting Stay connected: Publication APDL Commands Items in ANSYS MechanicaI (Workbench) v14.5 after Reaction Spectrum Analysis Submitted in Tips Techniques - Finite Element Evaluation (FEA) posts Figure 1: Reaction Spectrum Studies in the Project Schematic of Workbench Intro ANSYS Mechanical (Workbench) facilitates Response Spectrum Analysis.Either single-póint or multi-póint response spectrum evaluation can be performed.Depending on the outcomes required in Evaluation Settings for a Reaction Spectrum answer, velocity and acceleration results can end up being attained, in add-on to deflection, stress and strain.
Users sometimes wish to use APDL Commands Items in postprocessing to acquire results information and make Output Parameters. This write-up shows where information can be attained with postprocessing APDL Commands Items after a Reaction Spectrum Evaluation. Model Settings In a Reaction Spectrum Evaluation, Workbench Mechanical permits explanation of helps (zero displacement boundary problems) in the Modal environment. In single-point response spectrum evaluation, an excitation insight of Response Spectrum Displacement, or Velocity, or Acceleration can become added as an item in a Response Spectrum atmosphere. A global path for the excitation is definitely came into, and it is used to all constrained nodes during the SOLVE. Analysis Settings can be used to show whether in inclusion to the displacement that can be automatically created, a user would including to have Speed andor Speeding results generated: Figure 2: Evaluation Settings and a Simple Load in a Reaction Spectrum Evaluation During the Set ANSYS work that reads in the ds.dat file generated for an environment by Workbench Mechanical, outcomes are rescued in the RST results document in the foIder for the environment. Evaluation of v14.5 versions shows that with a Reaction Spectrum Analysis, the displacement outcomes are rescued in the RST document as Load Stage 4, Substep 1. The construction of an instance ds.dat document for a Reaction Spectrum evaluation demonstrates the formation of the Displacement, Velocity and Speed results. In the subsequent instance, Displacement, Speed and Acceleration results have got all been recently asked for in Analysis Settings. Ansys Mechanical Apdl Commands Code Pieces OfFour code pieces of the ds.dat file are proven. The reswrite order in the ds.dat file appends the outcome in data source memory to whichever RST document is described. In the first program code fragment used from the ds.dat file, we find a SOLVE fór a displacement evaluation. The historical cause for making use of Load Action 4 can be not apparent, but may be associated to old techniques employed in the ANSYS Mechanical APDL user interface. The Displacement outcome in Insert Step 4, Substep 1 contains diploma of independence displacement results at nodes, in add-on to derived tension and stress data. The Speed result in Fill Step 4, Substep 2 contains velocities rather of displacements ás the displacement outcomes at nodes, while the extracted outcomes (stress, stress etc.) are not physically meaningful. The Velocity outcome in Weight Stage 4, Substep 3 contains accelerations rather of displacement át nodes, and again the extracted results are not literally meaningful. The sticking with figure shows a deformation piece causing from a Reaction Spectrum analysis: Shape 3: Deformation Calculated in Single-point Response Spectrum Evaluation Understanding the above image needs examining Details configurations for several objects in the Contour. Even more than sufficient settings of vibration had been extracted to course the range of excitation frequencies utilized later. Number 4: Border Problems on the Modal AnalysisFixed Support The natural frequencies of vibration computed in the Modal atmosphere are outlined in a desk: Amount 5: Modal Frequencies Analysis Configurations in the illustration Response Spectrum analysis required a relatively simple SRSS mode combination (Observe Amount 2 above), and disregarded more sophisticated configurations that might be considered in accurate commercial function, for instance: Modes with closely-spaced natural frequencies. A Response Range insight of Displacement can be inserted to excite the structure in this instance.
