Research on the calculation method and influencing factors of the stiffness of the bending anti-roll torsion bar device of railway vehicles
摘要
Abstract
The stiffness calculation of the bending anti-roll torsion bar device is one of the key points in the design of anti-roll de-vices,which is related to the arrangement space,installation method and structural form of the anti-roll torsion bar device.The calculation model of system roll angle stiffness is established what takes into account all key parameters,including bending radi-us,bending angle,torsion arm length,rubber joint stiffness,and support sleeve stiffness based on the principle of energy conserva-tion.Based on the structure of bending anti-roll torsion bar device,the calculation model of roll angle stiffness is analyzed as an example,and the roll angle stiffness of the system is verified by combining with the bench test,and the test results show that the calculation model of the system roll angle stiffness is highly reliable and the error is only 3％.Finally,the calculation model is used to explore the influencing factors of roll angle stiffness,such as key dimensional parameters and stiffness of rubber parts.关键词
