Abstract

The invention discloses a rigidity analysis method for an automobile connector. The automobile connector is provided with a plurality of arm parts, wherein angles are formed among the arm parts. The rigidity analysis method comprises the steps that firstly, when parameter information of the automobile connector is received, an automobile connector model is established according to the parameter information of the automobile connector; secondly, when an analysis triggering command is received, a local coordinate system is established with the end face of one arm part being a reference in the automobile connector model, an arm part mechanical analysis model is established in the local coordinate system, mechanical performance information of the arm part mechanical analysis model is sent to a calculation module so that the rigidity of the arm part can be calculated; thirdly, after the rigidity of the arm part is received from the calculation module, whether rigidity analysis of the multiple arm parts is completed or not is judged, if yes, a fourth step is executed, and if not, the second step is executed again; fourthly, the rigidities of all the arm parts of the automobile connector are output. By means of the rigidity analysis method, the rigidities of the arm parts can be precisely obtained, the mechanical principle is clear, modeling is easy, and using is easy.

Description

technical field [0001] The invention relates to the technical field of automobile equipment analysis, in particular to a method for analyzing the stiffness of automobile joints. Background technique [0002] In the body, the car joints and other load-bearing parts together form a solid car body load-bearing structure, and the stiffness of the car joints will directly affect the stiffness of the vehicle. If the stiffness of the car joint is insufficient, it will cause large deformation in the local area, which will affect the normal use of the car. [0003] Taking the T-joint as an example, when performing stiffness analysis, it is necessary to analyze the bending stiffness and torsional stiffness of each joint in turn, and then compare it with the T-joint of the comparison vehicle to judge whether the stiffness of the T-joint of the vehicle is qualified or not. [0004] How to accurately analyze the stiffness of automobile joints to obtain accurate stiffness values ​​of aut...
