Problems solved by technology

However, due to the constraints of the analytical calculation of the deformation of the rubber bushing, the mutual coupling of the torsional deformation and bending deformation of the torsion tube, and the increase in the load of the torsional rubber bushing, for the internal offset non-coaxial cab stabilizer bar system The design of the inner diameter of 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 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 of CAD software development for the cab stabilizer bar system
