The invention relates to the technical field of computer-aided engineering technologies, in particular to a method for modeling a car steering system modal model. The method at least includes the steps that a steering wheel and a steering shaft are fixedly connected; a steering shaft and an upper steering transmission shaft are connected to form an upper cardan joint; the upper steering transmission shaft and a lower steering transmission shaft are connected through a spline; the lower steering transmission shaft and a steering gear shaft of a steering gear are connected to form a lower cardan joint; a rack and pinion mechanism is simulated through multipoint restriction. By means of the method, the car steering system modal model capable of accurately reflecting the transmission relationship between force of constituent parts of a system is obtained, and shaking or vibration of the steering system can be accurately reflected in a computer. The problem that an existing computer modeling method cannot accurately reflect the transmission relationship between the force of the constituent parts of the steering system is solved.
Description
technical field [0001] The invention relates to the technical field of computer-aided engineering (CAE), in particular to a modeling method of a modal model of an automobile steering system, capable of accurately simulating the force transfer relationship between various components of the steering system in a computer. Background technique [0002] CAE can help engineers involved in multi-disciplinary and multi-field development of products quickly and effectively. The modal model of the automobile steering system can be established by using the finite element method to establish a finite element grid model, which can simulate and calculate the static or dynamic response of each component of the steering system when it is subjected to external forces, and can replace the actual vehicle test, thereby effectively reducing the design cycle and saving energy. design cost. The steering system generally includes a steering wheel, a steering shaft, an upper steering transmission s...
