Description

technical field [0001] The invention discloses a clamping structure rigidity simulation modeling method, system, terminal and storage medium, belonging to the technical field of computer aided engineering. Background technique [0002] The chassis sub-frame, T-arm, shock absorber fork, etc. are in the form of "ear arms". While meeting the strength and durability performance, the bolt clamping stiffness between the "ear arms" must also meet certain design requirements. That is, under the action of the bolt pre-tightening force, the sleeve structure between the "ear arms" cannot be loosened under the action of external force, otherwise abnormal noise will occur. However, the general subframe structure usually has 4-6 similar "ear arm" structures, and it is necessary to manually complete the modeling of 4-6 hexahedral bolts and sleeves. The modeling calculation process involves many factors and the modeling cycle is long , Low work efficiency and other issues. Contents of th...
