Optimization of Body Attachment for Road Noise Performance

It is common knowledge that body attachment stiffness is an important factor of road noise performance. Thus, a high stiffness of body attachments is required, and determining their optimized stiffness and structure is necessary. Therefore, a method for improving body attachment stiffness and validating the relationship between stiffness and road noise through CAE and experimental trials was tested. Furthermore, a guideline for optimizing body structure for road noise performance was suggested.
