Kim, H., Oh, S., Kim, K., Lee, J. et al., "Optimization of Body Structure for Road Noise Performance," SAE Technical Paper 2014-01-0010, 2014, doi:10.4271/2014-01-0010.
It is common knowledge that body structure is an important factor of road noise performance. Thus, a high stiffness of body system is required, and determining their optimized stiffness and structure is necessary. Therefore, a method for improving body 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.
