- Summary:
- Noise and Vibrations of vehicles are becoming importantparameters in automobile industry for its influence onenvironmental aspect and comfort perceived by occupants. NVHparameters are driving factors in current vehicle design strategy.Drivers comfort is extremely important, and driver'sexpectations from commercial and heavy-duty trucks are similar to apassenger car. Other trends in commercial vehicle segment such asengine downsizing, weight, cost reduction and meeting stringentemission norms have influenced on vehicle design dynamics. Theseparameters often contribute to vehicle NVH issues. Consideringthese new trends in commercial segment, it becomes challenging foran NVH engineer to provide optimized solutions. The NVH issuescould be related to the various subsystems in the vehicle and caninteract with natural frequency of many components such asdriveline, axle, transmission steering wheel et cetera In commercialvehicles, driveline design parameters, power train mounting systemand secondary isolation of cab mounting system plays a vital rolein providing optimized solutions to the NVH refinement. This paperrepresents a case study on a commercial vehicle for low frequencyNVH performance evaluation and refinement using experimentaltechniques to achieve targeted NVH performance. This paperdescribes optimization of powertrain mounts, cab mounts anddriveline design parameters through DOE method to reduce thevibrations transmitted in a passenger cabin at tactile locationsand corresponding cabin noise. The results of the analysis depictthe significant improvement in vibration transmitted to theDriver's and passenger locations with reduced stiffness ofengine mounts, cab mounts and optimized driveline parameters
