Problems solved by technology

However, due to the constraints of the key issue of analytical calculation of the deformation of the rubber bushing, a reliable analytical design method has not been given for the design of the torsion tube diameter of the coaxial cab stabilizer bar system, and only the rubber bushing For the influence of the stiffness of the stabilizer bar system, use a conversion factor to approximate the diameter of the torsion tube of the coaxial stabilizer bar system, and it is difficult to obtain an accurate and reliable design of the inner diameter and outer diameter of the torsion tube of the coaxial cab stabilizer bar system value
At present, for the diameter of the coaxial cab stabilizer bar at home and abroad, most of them use ANSYS simulation software to simulate and verify the characteristics of the coaxial stabilizer bar system with a given structure through solid modeling. Although this method can obtain a relatively reliable However, since this method cannot provide accurate analytical calculation formulas, it cannot realize analytical design, let alone meet the requirements of CAD software development for the coaxial cab stabilizer bar system

Description

technical field [0001] The invention relates to a vehicle cab suspension, in particular to a design method for the diameter of a coaxial cab stabilizer bar. Background technique [0002] For the full-floating cab suspension system, a stabilizer bar system must be installed to meet the design requirements for the cab’s roll angle stiffness when the vehicle is turning. Among them, the roll angle stiffness of the cab suspension system is not only related to the It is related to the structure and spring stiffness, but also to the stiffness of the stabilizer bar system, that is, to the inner diameter and outer diameter of the torsion tube of the cab stabilizer bar system. However, due to the constraints of the key issue of analytical calculation of the deformation of the rubber bushing, a reliable analytical design method has not been given for the design of the torsion tube diameter of the coaxial cab stabilizer bar system, and only the rubber bushing For the influence of the s...
