Abstract

The invention relates to a method for checking the stress strength of a torsion tube of an external offset non-coaxial cab stabilizer bar, and belongs to the technical field of vehicle cab suspension. The present invention establishes the bending load coefficient of the torsion tube by using the relationship between the bending and torsional deformation of the torsion tube and the relationship between the external offset non-coaxial cab stabilizer bar system and the torsion tube's structural parameters, material characteristic parameters and load , and through the bending normal stress and torsional shear stress of the torsion tube, a method for checking the torsion tube stress strength of the external offset non-coaxial cab stabilizer bar is established. Through example calculation and ANSYS simulation verification, it can be seen that this method can obtain accurate and reliable calculation value of torsion tube stress intensity, which provides a reliable stress intensity check method for the design of cab stabilizer bar system. Using the method can improve the design level, quality and performance of the stabilizer bar system in the cab, and improve the driving comfort and safety of the vehicle; at the same time, it can also reduce design and test costs and speed up product development.
