Analysis of the acoustic characteristics of truck cabins.
A case study of modeling the vehicle body structure and the acoustic space inside the cabin, and conducting coupled frequency response analysis.
We would like to introduce our analysis of "Cabin Acoustic Characteristics of Tracks Using Acoustic Coupled Analysis Function." In recent years, considering low noise environments has become very important. It is effective to use finite element method analysis to understand the acoustic characteristics of the cabin during the design phase and to reduce noise transmission to the operator through structural considerations. In this case, we used the Simcenter Nastran structural-acoustic coupled analysis function to model the vehicle body structure and the acoustic space within the cabin, conducting a coupled frequency response analysis to determine the acoustic transmission characteristics from the vehicle body mounting points to the operator's ear position. 【Case Overview】 ■ Function Used: Simcenter Nastran Structural-Acoustic Coupled Analysis Function ■ Analysis Content - Model the vehicle body structure and the acoustic space within the cabin - Conduct coupled frequency response analysis - Determine the acoustic transmission characteristics from the vehicle body mounting points to the operator's ear position *Detailed information about the case can be viewed through the related links.
