Sensitivity is extremely important in computer aided material and structural design. The present paper focuses on the sensitivity with respect to the design variables of truck body. This paper proposes a solution procedure of truck body for natural frequency sensitivity calculation in vibration analysis and optimization using a frequency shift combined approximations (FSCA) approach. These sensitivity analysis formulations are based on the reduced basis method and finite difference derivative. Using a shift coefficient, accurate sensitivities of natural frequency can be obtained. Truck body with large degrees of freedom demonstrates the accuracy of the sensitivity reanalysis method. Compared to the exact solution, the proposed method is efficient and easy to implement. With the sensitivity information, satisfying materials and thicknesses can be selected. The proposed method is suitable for material and structural design and optimization
