Embodiment Construction
[0029] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0030] The steps of the finite element modeling method for quickly simulating bolted connections of the present invention are as follows:
[0031] 1) First determine the thickness of the board to be connected (thickness of the upper board t 1 3mm, lower plate thickness t 2 is 4mm), material properties (E is 71000MPa) and the fasteners used are titanium bolts, diameter (d is 6mm), material properties (E 1 is 109000MPa),;
[0032] 2) Determine the fastener compliance coefficient of the single-sided lap joint;
[0033] for figure 2 For the simple shear connector shown, the elastic compliance coefficient C of the fastener can be determined by the following formula:
[0034]
[0035] In the formula: d—the diameter of the fastener;
[0036] t 1 — the thickness of the thinner plate;
[0037] t 2 — the thickness of the thicker plate;
[0038] E—Elastic ...
