The reduction of noise in motor vehicle compartments has become increasingly important in recent years. This trend now includes the heavy-duty truck. The objective of this study was to investigate the load transfer paths in the cabin structures of heavy-duty trucks under static loading, and to apply the results to reduce vibration in cabins. In a preliminary simulation using a simple model, it is shown that the floor panel vibration is closely related to the stiffness of the front cross-member of the floor structure. A simple mass-spring model for the truck cab is developed to relate the vibration problem to the static structural analysis. The authors outline the concept of load transfer path in a static analysis: 1. Concept of load path analysis (connectivity index, load transfer path, conditions for a desirable structure); 2. Optimization using U* and the three conditions. Load path U* analysis using the finite element method show that the low stiffness of the front cross-member is caused by discontinuities and no uniformities in the load praths.
