A steering transmission shaft optimization design method, computer equipment and storage medium

Abstract

The invention belongs to the field of automobile steering transmission shaft design, and discloses a steering transmission shaft optimization design method, including S1, establishing and positioning a steering column model and a steering machine model through CATIA; S2, inserting a steering transmission shaft model, and associating the above-mentioned model; S3 , according to the length parameter of the output end of the steering column and the length parameter of the output end of the steering gear, automatically generate the steering transmission shaft parameter; S4, generate the first steering torque fluctuation curve and the second steering torque fluctuation curve according to the steering transmission shaft parameter, and convert the first steering torque The torque fluctuation curve and the second steering torque fluctuation curve are drawn in the same steering torque fluctuation chart; S5, adjust the length parameter, and stop the adjustment when the updated steering torque fluctuation chart meets the design requirements; S6, check the steering drive shaft and its movement Whether the envelope and surrounding parts meet the layout requirements, if so, complete the optimal design of the steering drive shaft. The invention can realize the optimized design of the steering transmission shaft without running simulation analysis.

Description

technical field [0001] The invention relates to the field of automobile steering transmission shaft design, in particular to a steering transmission shaft optimization design method, computer equipment and storage media. Background technique [0002] The steering system operating mechanism mainly includes the steering wheel, steering column, and steering drive shaft. In order to facilitate the layout, improve the safety of the frontal collision of the car, and facilitate disassembly and assembly, generally, the steering drive shaft is connected by two cross shaft universal joints. Due to the non-uniform velocity of cross-axis universal joint transmission, in order to avoid torque fluctuation, the following conditions need to be met: [0003] 1. The output end of the steering column and the axis of the output end of the steering gear are in the same plane; [0004] 2. The angle between the output end of the steering column and the steering transmission shaft and the output ...

Problems solved by technology

However, this method has the following disadvantages: first, due to the complex environment of the engine room, it is necessary to repeatedly adjust the layout of the steering drive shaft according to the change of the environmental plan, the adjustment process is cumbersome and the workload is large; second, each adjustment of the steering drive shaft needs to be carried out Simulation analysis, high degree of work repetition, time-consuming and laborious; third, the steering torque fluctuation and layout data cannot be viewed at the same time, it is difficult to balance the relationship between performance and layout, and find the optimal solution
