The invention discloses a method and device for simulating the stiffness of a connecting point, belonging to the technical field of computer-aided design. The method includes: establishing a connection point information configuration table, the connection point information configuration table records the initial information of n connection points on the vehicle body, and the n is an integer greater than 1; according to the connection point information configuration table, the The n connection points are respectively subjected to working condition loading to obtain a response parameter for indicating a response to the working condition loading of each of the connection points; each of the response parameters is substituted into the target analysis model to obtain each The stiffness of the connection point, the target analysis model is used to simulate the stiffness of the connection point. The invention solves the problem that the analysis process of the stiffness of the connection point is complicated and has a high error rate, realizes the effect of simplifying the analysis process and reducing the error rate, and is used for simulating the stiffness of the connection point of the vehicle body.
Description
technical field [0001] The invention relates to the technical field of computer-aided design, in particular to a method and device for simulating stiffness of connection points. Background technique [0002] During the development of the vehicle, a large amount of analytical data about the connection points of the body is required as the basis for project development. The connection points of the body and other load-bearing parts on the body together form a solid body load-bearing structure. The connection points of the body should maintain sufficient rigidity. If the stiffness is insufficient, it will cause large deformations in local areas, thus affecting the normal use of the vehicle. . Among them, the connection points of the body include various types of connection points such as suspension installation points, seat installation points and pedal installation points. Stiffness refers to the ability of a structure to resist elastic deformation when a force is applied. ...
