CASE ｜MITSUBISHI MOTORS CORPORATION 様 Leak path analysis to improve noise insulation performance by Elsyca LeakageMaster

Challenges

  • Identifying the locations of gaps and holes in auto body to estimate from where the noise enters into the cabin.
  • To give feedback on the leakage paths to designers before the actual vehicle is completely developed.
  • Storing the knowledge in a database to use it for the initial development stage of new vehicles.

CAE software

Mitsubishi Motors - whose involvement in automobile manufacturing began with “MITSUBISHI MODEL A” in 1917 as the first mass-production automobile in Japan – has been releasing many famous vehicles including more recently the “Outlander PHEV”, the result of a high-level of integration between electrification and all-wheel drive technologies and the “Pajero sports” derived from “Pajero” which led the RV (Recreational Vehicle) boom. Technology innovation for NVH of the auto body is necessary to pursue the comfortability of driving. This article introduces how upfront numerical leak path analysis using Elsyca LeakageMaster was used to improve noise insulation performance.
