SIDLAB 4 Release Highlights

SIDLAB 4.4.0 Release Highlights

  1. New measurement configuration for 3-port mufflers: Using configuration 5, 3-port mufflers can be measured simultaneously by connecting the new SIDLAB test rig designed specially for this type of mufflers. No need to dissemble half of the rig and assemble it with other port to measure the full performance of the 3-port muffler, just assemble the new rig to the muffler ports and use SIDLAB to acquire all the data and SIDLAB will do full characterization of your muffler using 3X3 matrices.
  2. New technique for extending the measurement range: In the old versions of SIDLAB Acquisition, the measurement frequency range is determined by the limit of low frequency and high frequency microphones spacing, taking into consideration a necessity of overlap between the tow ranges. In this version, a new technique based on least squares is developed to allow for a frequency gap between the two ranges which extend the measurement range of the test rig for all configurations.
  3. New lined duct element with variable lining thickness: The new model is based in AHRI standard which provides model with variable lining thickness. This will allow more flexibility in the simulation instead of fixed one-inch lining.
  4. Improvements for the liquid fluids results.
  5. Improvements in IC Engine model.
  6. High Frequency results are exported automatically in table format in more details.
  7. Improvement for flow noise results in High Frequency module.
  8. Licensing improvements.
  9. Updated MATLAB runtime engine MCR 2020a.
  10. High Frequency elements improvement.
  11. Bug fixes.
