Problems solved by technology

However, since the external offset non-coaxial cab stabilizer bar is a coupled body composed of rigid body, elastic body and flexible body, and is restricted by key issues such as bending deformation, torsional deformation and mutual coupling between loads , the analysis and calculation process is very complicated. Therefore, a reliable analytical design method has not been given for the design of the inner diameter of the torsion tube of the external offset non-coaxial cab stabilizer bar system
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 simulate and verify the characteristics of the stabilizer bar with given parameters, it cannot provide an accurate analytical design formula, cannot realize the analytical design, and cannot meet the requirements for the development and design of the cab stabilizer bar system CAD software

Abstract

The invention relates to a design method for the inner diameter of a torsion tube of an external offset non-coaxial cab stabilizer bar, and belongs to the technical field of cab suspension. According to the design requirement value of the cab roll angle stiffness, the structural parameters and material characteristic parameters of the stabilizer bar system, the outer deflection can be adjusted through the radial stiffness of the rubber bushing, the equivalent combination line stiffness and the load coefficient of the torsional rubber bushing. Analytical design of the inner diameter of the torsion tube of the non-coaxial cab stabilizer bar. Through the design example and ANSYS simulation verification, it can be seen that the method can obtain the accurate and reliable design value of the inner diameter of the torsion tube of the external offset non-coaxial cab stabilizer bar, which provides a reliable design method for the design of the stabilizer bar system, and can be used for CAD software The development has laid a solid technical foundation. The method can improve the design level, quality and performance of the cab suspension and the stabilizer bar system, improve the ride comfort and safety of the vehicle; at the same time, it can also reduce the design and test costs and speed up product development.

Description

technical field [0001] The invention relates to a vehicle cab suspension, in particular to a design method for the inner diameter of a torsion tube of an external offset non-coaxial cab stabilizer bar. Background technique [0002] The inner diameter and wall thickness of the torsion tube of the external offset non-coaxial cab stabilizer bar system have an important influence on the stiffness and performance of the stabilizer bar system. It not only directly affects the torsional deformation of the torsion tube, but also affects the bending deformation, torsion The load and deformation of the rubber bushing have an important influence. In the actual design of the stabilizer bar system, the inner diameter and wall thickness of the torsion tube are often designed under the condition of a given torsion tube outer diameter. However, since the external offset non-coaxial cab stabilizer bar is a coupled body composed of rigid body, elastic body and flexible body, and is restricte...
