Abstract

The idle vibration of steering wheel in the vehicle steering system is an important index to evaluate its comfort． A calculation method of steering system's natural frequency was put forward． Through sensitivity analysis， the thicknesses of five sheet metal parts at the upper and lower connections of steering system was determined as the design variables． Based on the combination of response surface model and sequential quadratic programming algo- rithm，the modal optimization method of steering system was presented． The first-order natural frequency of the system increased by 2. 66 Hz when the mass of the steering system increased by 0. 14 kg． The steering system mo- dal analysis and the proposed optimization method can provide certain guidance for steering system design．

Key words： steering system; finite element analysis; Hammersley experiment; response surface model
