I m trying to update my FE model with the harmonic test results (i.e. compare FRF results from analysis and test)Mech_Engineer said:Sorry, I haven't used the feature you're trying to. What specific features of your geometry are you trying to optimize for harmonic response?
Harmonic analysis in Ansys APDL is a method of solving mechanical engineering problems that involve dynamic loading, such as vibrations and oscillations. It takes into account the frequency content of the loading and calculates the response of the system at each frequency.
Harmonic analysis in Ansys APDL is commonly used to solve problems related to vibrations and oscillations, such as structural dynamics, modal analysis, and natural frequency analysis. It can also be used for steady-state thermal analysis and to study the effects of harmonic loading on mechanical systems.
Harmonic analysis in Ansys APDL allows for a more accurate and comprehensive analysis of dynamic loading compared to traditional static analysis. It can also provide insight into the frequency response of a system, which is useful for optimizing design parameters and identifying potential failure modes.
One limitation of harmonic analysis in Ansys APDL is that it assumes linearity of the system, which may not always be the case in real-world scenarios. Additionally, it may not be suitable for solving problems with highly complex geometries or nonlinear material properties.
Harmonic analysis in Ansys APDL involves breaking down a complex dynamic loading into multiple simpler harmonic load cases, each with a specific frequency and amplitude. The software then solves for the response of the system at each frequency, and the results are combined to obtain the overall response. This process is repeated for each load case to obtain a frequency response curve for the system.
