Embodiment
[0024] figure 1 It is a schematic diagram of the steps of the method of applying radial force to the three-dimensional model of the ring part according to the embodiment of the present invention.
[0025] Such as figure 1 As shown, the specific load application process will be described in detail below.
[0026] The first step is to establish the 3D model of the automobile tire in ABAQUS, after a series of setting work, such as the setting of material properties, the setting of grid density, etc., and then obtain the flexible body file of the tire, and save it in the format of chetai.mnf.
[0027] In the second step, for the obtained flexible body file, the grid node coordinates and node serial numbers are extracted in ABAQUS, and finally the extracted grid node coordinates and node serial numbers are saved in .rpt format. Open the saved .rpt file, which contains the node coordinate values before deformation and the node coordinate values after deformation, delete the no...

The invention provides a method for applying three-dimensional model radial force of a ring part. The method comprises the steps of 1, establishing a three-dimensional model of the ring part, setting corresponding material attributes and grid density, conducting mesh generation after grid convergence is verified, and generating a tire flexible body file; 2, extracting the coordinates and serial numbers of grid nodes obtained after mesh generation; 3, decomposing force F to be applied at the position of the grid node pointing at the circle center of the ring part in the directions of x axis and y axis by means of the force decomposing principle, so that Fx and Fy are obtained, wherein Fx= Lambda1F sin alpha, Fy=Lambda2F cos alpha, the equation of alpha is shown in description, Lambda1 and Lambda2 are arbitrary values and determined by actual load, the values of Lambda1 and Lambda2 can be positive and negative to show the direction of force, and x and y are coordinates of the grid node; 4, summarizing Fx and Fy obtained after decomposition of forces of all the grid nodes, and making a form about node number, force name and force value; 5, importing the form about node number, force name and force value into the three-dimensional model to finish application of radial force of the three-dimensional model.
Description
technical field [0001] The invention belongs to the field of computer programs, in particular to a method for applying radial force in a three-dimensional model. Background technique [0002] ADAMS software is a software developed by Mechanical Dynamics Inc. (now merged into MSC Corporation) of the United States, which is specially used for virtual product development in mechanical products. Through the establishment of multi-body dynamic models and virtual experiments by this software, it can help designers find design defects in the product development stage, and propose a series of improvement plans based on the analysis and research of the defects. The use of this software greatly reduces the cost in the process of mechanical product development and improves the efficiency in the field of mechanical product design and development. Before using the software for dynamics and kinematics analysis, it is necessary to apply force and motion in a certain direction to the model...
