Problems solved by technology

Due to the constraints of the analytical calculation of the deformation of the rubber bushing, the mutual coupling of the torsional deformation and the bending deformation of the torsion tube, and the increase in the load of the torsional rubber bushing, the internal offset non-coaxial cab stabilizer bar system The design of the swing arm length has not been given a reliable analytical design method
At present, most of the design of cab stabilizer bar system at home and abroad is to use ANSYS simulation software to simulate and verify the characteristics of the cab stabilizer bar system with a given structure through solid modeling, although this method can obtain relatively reliable simulation values However, since ANSYS simulation analysis can only verify the stabilizer bar with given parameters, it cannot provide accurate analytical design formulas, cannot realize analytical design, and cannot meet the requirements of CAD software development for the cab stabilizer bar system

Using this method can not only improve the design level and quality of the cab suspension and stabilizer bar system, improve the ride comfort and safety of the vehicle, but also reduce design and test costs and speed up product development.

Description

technical field [0001] The invention relates to a vehicle cab suspension, especially a method for designing the length of a swing arm of an internal offset non-coaxial cab stabilizer bar system. Background technique [0002] For the inner offset non-coaxial cab stabilizer bar system, the length of the swing arm not only affects the bending deformation of the torsion tube, the load and deformation of the torsion rubber bushing, but also has an important impact on the performance of the stabilizer bar. Although the stabilizer bar system is only composed of swing arm, torsion tube and rubber bushing, it is a coupled body composed of rigid body, elastic body and flexible body. Due to the constraints of the analytical calculation of the deformation of the rubber bushing, the mutual coupling of the torsional deformation and the bending deformation of the torsion tube, and the increase in the load of the torsional rubber bushing, the internal offset non-coaxial cab stabilizer bar s...
