Problems solved by technology

Although the inner offset non-coaxial cab stabilizer bar system is composed of swing arm, torsion tube and rubber bushing, it is a coupled body composed of rigid body, elastic body and flexible body. very complicated
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 torsional Pipe length design, has not been able to give 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

Abstract

The invention relates to a design method for the length of a torsion tube of an internal offset non-coaxial cab stabilizer bar system, and belongs to the technical field of cab suspension. According to the design requirements of the roll angle stiffness of the stabilizer bar system, the structural parameters and material characteristic parameters of the stabilizer bar system, the mathematical model and the Matlab program are designed through the length of the torsion tube, and the non-coaxial cab stabilizer bar system is offset inwardly. The length of the torsion tube is solved for the design. Through the design example and simulation verification, it can be seen that the method can obtain accurate and reliable design value of the torsion tube length of the inner offset non-coaxial cab stabilizer bar system, which provides a reliable design for the design of the cab suspension and stabilizer bar system method, and laid a reliable technical foundation for the development of CAD software. 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.

technical field [0001] The invention relates to a vehicle cab suspension, in particular to a design method for the length of a torsion tube of an internal offset non-coaxial cab stabilizer bar system. Background technique [0002] The length of the torsion tube not only affects the torsional deformation and bending deformation of the torsion tube, the load and deformation of the torsional rubber bushing, but also has an important influence on the performance of the inner offset non-coaxial cab stabilizer bar system. Although the inner offset non-coaxial cab stabilizer bar system is composed of swing arm, torsion tube and rubber bushing, it is a coupled body composed of rigid body, elastic body and flexible body. very complicated. 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 bu...
