Abstract

Finite element method was used to simulate and analyse the dynamic characteristics of commercial vehicle hydraulic bulging axle housing, and the vibration characteristics, stress spectrum diagram of dangerous area and transient response stress and deformation of the axle housing under the excitation of bench test were obtained. The results show that the lowest natural frequency of the axle housing is 95.63Hz, which is greater than the maximum excitation of the road surface in general, so there is generally no resonance. Even if the bridge housing resonates under the external excitation of 200Hz, the maximum dynamic stress is still less than the allowable stress of the bridge housing material. The dangerous parts of the axle housing are mainly distributed in the bearing installation of the axle housing and the arc transition zone from the straight arm of the axle housing to the middle part of the axle housing. Under the excitation of bench test, the maximum dynamic stress and deformation of the dangerous part of the axle housing meet the design requirements. To sum up, the overall dynamic characteristics of the liquid expanded axle housing theoretically meet the requirements of use.
