Spectrum Analysis The damping proportional to the mass (ALPHAD) is now supported in spectrum and power spectral density (PSD) analyses. . If data is from a full transient analysis (ANTYPE,TRANS with TRNOPT,FULL): Δt = input time step size (input as DTIME on RESP command) or if no input is provided: Feb 28, 2026 · The integration time step (argument DTIME on the resp command) and the damping coefficient (argument dampRatio ) are constant over the frequency range. Get help from Ansys experts and peers through the Ansys Learning Forum. A screenshot is shown below right) Using APDL Commands Objects in Postprocessing to Extract Data and Create Output Parameters Ansys Mechanical Workbench supports Response Spectrum Analysis. This is illustrated in Figure 17. Three types of input excitation spectrum are supported: displacement, velocity, and acceleration. Either single-point or multi-point response spectrum analysis can be performed. Time Step Size The time step size (Δt) is selected in the following way. The response spectrum can then be specified in a single-point or multiple point spectrum analysis (ANTYPE,SPECTR with SPOPT,SRSS or MPRS) to calculate the overall response of a structure. The number of calculations done per response spectrum curve is the product of the number of input solution points (TMAX - TMIN)/ DTIME and the number of frequency points (frequencies located in Sep 16, 2020 · Ansys Employee In the input below the POST26 RESP command is used to compute the shock response spectrum for a 20g triangular acceleration of 10 milli-sec duration. Enhancements to the RESP command allow you to generate the response spectrum from an acceleration input, and to determine the pseudo-velocity and pseudo-acceleration response spectrum. Response spectrum is a mode superposition linear analysis that uses the results of a modal analysis with a known spectrum to calculate displacements and stresses in the model. Terms and Conditions Legal Notices Privacy Policy Send Feedback The RESP command generates a displacement, velocity, or acceleration response spectrum from a given displacement or acceleration time-history. A response spectrum is generated by imposing the motion of the point of interest on a series of single-mass oscillators over a period of time and calculating the maximum displacement, velocity, or acceleration. 3. The mode coefficients are calculated by the program from the modal analysis participation factors and However, unlike a random vibration analysis, responses from a response spectrum analysis are deterministic maxima. The number of calculations done per response spectrum curve is the product of the number of input solution points (TMAX - TMIN)/ DTIME and the number of frequency points (frequencies located in 17. It is not a WB Mechanical function/feature. The integration time step (argument DTIME on the RESP command) and the damping coefficient (argument dampRatio) are constant over the frequency range. 1. Depending on the results requested in Analysis Settings for a Response Spectrum solution, velocity and acceleration results can be obtained, in addition to Get help from Ansys experts and peers through the Ansys Learning Forum. The input assumes that a modal analysis has been done and Given a motion as output from a transient dynamic analysis, POST26 generates a response spectrum in terms of displacement, velocity, or acceleration.
