Designing method for length of twisted tube of inward-biased non-coaxial cab stabilizer bar system

The invention relates to a designing method for the length of a twisted tube of an inward-biased non-coaxial cab stabilizer bar system, belonging to the technical field of cab suspension. The designing method comprises the steps of designing a mathematical model and a Matlab procedure based on the length of the twisted tube according to the designing requirement of the rolling angle stiffness of the stabilizer bar system as well as the structural parameter and material characteristic parameter of the stabilizer bar system; and solving and designing the length of the twisted tube of the inward-biased non-coaxial cab stabilizer bar system. A design embodiment and simulation verification prove that an accurate and reliable length design value of the twisted tube of the inward-biased non-coaxial cab stabilizer bar system can be obtained by using the method, the reliable designing method is provided for designing cab suspension and the stabilizer bar system, and the reliable technological basis is laid for CAD software development. By using the method, not only can the designing level and quality of cab suspension and the stabilizer bar system as well as the riding comfort and safety of a vehicle be improved, but also the designing and experimenting expenses can be reduced, and the product development speed can be increased.
