Problems solved by technology

However, due to the constraints of key issues such as rubber bush deformation and stiffness coupling, for the coaxial cab stabilizer bar system, the rubber bush outer circle radius r b However, a reliable analytical design method has not been given, and only a conversion factor selected in the range of 0.75 to 0.85 for the influence of the rubber bushing on the stiffness of the stabilizer bar system can be used for other structural parameters of the coaxial stabilizer bar. Approximate design, therefore, it is difficult to achieve the design requirement value of the roll angle stiffness of the coaxial cab stabilizer bar system
At present, for the coaxial cab stabilizer bar system 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 relatively reliable simulation values ​​can be obtained However, since this method cannot provide accurate analytical calculation formulas, it cannot meet the requirements of analytical design, let alone the development of CAD software 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 outer circle radius of a coaxial cab stabilizing rod rubber sleeve. Background technique [0002] The structural size of the rubber bushing affects the roll angle stiffness of the cab suspension system, and affects the ride comfort and ride comfort of the vehicle. Among them, the outer circle radius r of the rubber bushing b It has a significant influence on the roll angle stiffness of the stabilizer bar system. In the design of the actual cab suspension system, in order to meet the design requirements of the roll angle stiffness, it is necessary to adjust the design of the rubber bushing structure to meet the design requirements of the cab roll angle stiffness while other structures remain unchanged. However, due to the constraints of key issues such as rubber bush deformation and stiffness coupling, for the coaxial cab stabilizer bar system, the rubber bush o...
