Abstract

The invention relates to a method for checking the stress strength of a torsion tube of an internal offset non-coaxial cab stabilizer bar, belonging to the technical field of vehicle cab suspension. According to the internal offset non-coaxial cab stabilizer bar system and the structural parameters and material characteristic parameters of the torsion tube, the invention uses the relationship between the bending and torsional deformation of the torsion tube and the load to establish the bending load coefficient of the torsion tube, and Through the bending normal stress and torsional shear stress, a method for checking the torsion tube stress strength of the inner offset non-coaxial cab stabilizer bar is established. Through the example calculation and ANSYS simulation verification, it can be seen that the method can obtain accurate and reliable calculation value of the torsion tube stress intensity of the internal offset non-coaxial cab stabilizer bar, which provides a reliable stress intensity calibration for the design of the cab stabilizer bar system. Kernel calculation method. 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 the design and test costs.

Description

technical field [0001] The invention relates to a vehicle cab suspension, in particular to a method for checking the torsion tube stress strength of an internal offset non-coaxial cab stabilizer bar. Background technique [0002] Due to the constraints of key issues such as the torsion and bending deformation of the torsion tube and the mutual coupling between loads, a reliable method for checking the stress intensity of the torsion tube has not been given for the internal offset non-coaxial cab stabilizer bar system. At present, most of the stress strength checks of the cab stabilizer bar system at home and abroad use ANSYS simulation software to simulate and analyze the stress strength of the torsion tube through solid modeling. Although this method can obtain relatively reliable simulation values, however, due to Can not provide accurate analytical calculation formula, therefore, can not meet the cab stabilizer bar system analytical design and CAD software development req...
