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 offset in the torsion tube 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 an accurate analytical design formula, cannot realize the analytical design, and cannot meet the requirements of CAD software development for the cab stabilizer bar system

Description

technical field [0001] The invention relates to a vehicle cab suspension, in particular to a method for designing the inner offset of a torsion tube of an inner offset non-coaxial cab stabilizer bar. Background technique [0002] The inner offset non-coaxial cab stabilizer bar system is a coupling body composed of rigid body, elastic body and flexible body. Among them, the size of the internal offset of the torsion tube not only affects the bending deformation of the torsion tube, the load and deformation of the torsion rubber bushing, but also has an important influence on the performance of the stabilizer bar. 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 offset in the torsion tube has not be...
