Optimization of Truck Chassis for Frequency Response

FE analysis provides an optimal and quick way to optimize the structural design of any vehicle. When considering the structural design of a vehicle, chassis design plays an important role for all the parts are attached to the chassis only. The better the design of the chassis better is the vehicle. Most of the current heavy vehicles are using C Sections for their chassis design. The current work focuses on using I-section in place of C Section. For this an 8X8 heavy truck chassis is taken and a modified with I sections. Different analyses, namely static, modal and harmonic analyses are performed on both the chasses. It is found that the I-section chassis performs better than C section chassis. Results are discussed in the paper.
