Description

Technical Field

[0001] The invention relates to a design simulation method and system for a double-arm main beam arc-shaped metal gate, belonging to the technical field of hydraulic metal gates. Background Art

[0002] Hydraulic metal gates are key equipment used in water conservancy projects to control water flow, adjust water levels, discharge flood water or divert water. They can block or release water flow to ensure the safe operation of hydraulic structures such as reservoirs and rivers. They provide reliable water flow management and regulation functions in flood control, water supply, power generation, shipping and other fields, ensuring the safety of people’s lives and property and the efficient use of resources.

[0003] Double-arm main beam arc metal gate is one of the commonly used gate forms in hydraulic metal gates and is widely used in dams, ship locks, water diversion and flood discharge projects. Double-arm main beam arc gate has a complex structure. In traditional design, the dimensions of all components are preset by experience or standards. Designers need to check and verify after the overall design is completed. If a component does not meet the requirements, it is often necessary to redesign the entire gate structure, recalculate and check, which makes the gate design process time-consuming and repetitive.

[0004] Furthermore, the Chinese patent (CN103400002B) discloses a planar gate design simulation platform, which includes modules such as overall gate parameters, beam grid arrangement, panel design, beam grid design, main beam design, diaphragm design, transverse connection system, side beam design interface, roller and slider design, and calculation of gate opening force and lifting lug.

[0005] Although the above scheme can realize the design simulation of planar gates, it is necessary to know the size information of each component before simulation in order to perform verification and adjustment. However, the size calculation of each gate component is cumbersome and error-prone, which still causes the gate design process to take too long. Therefore, the component size information cannot be automatically generated, which will affect the efficiency and accuracy of gate modeling and simulation.

[0006] At the same time, the above scheme is only applicable to plane gates. There are differences in the structural composition of plane gates and double-arm main beam arc gates. Therefore, the above scheme cannot be applied to the design simulation of double-arm main beam arc metal gates.

[0087] In this embodiment S6, the design parameters obtained in S1-S5 are simultaneously input into the automatic modeling script for the double-arm main beam gate. The script will sequentially establish a three-dimensional simulation object of the gate panel, a three-dimensional simulation object of the gate main beam, a three-dimensional simulation object of the gate longitudinal beam, and a three-dimensional simulation object of the gate arm, and then merge the simulation objects of each component into a three-dimensional simulation object of the double-arm main beam arc gate.

[0088] In this embodiment, the process of component design, verification and adjustment is adopted to independently design and verify each component, avoiding large-scale adjustments after the overall design is completed, greatly improving the design efficiency. At the same time, the method can be automated through programming. The designer only needs to input a small number of basic parameters such as the bottom sill elevation, support hinge elevation, design water head, orifice width, orifice height, etc. to complete the design of the entire double-arm main beam radial gate, and automatically generate a three-dimensional simulation object of the gate.

[0089] A specific embodiment of the present invention for designing and simulating a double-arm main beam arc gate of a certain leakage hole: A certain spillway adopts a double-arm main beam radial gate, and the basic design parameters are as follows: The sill elevation is 83.955m, the support elevation is 87.455m, the design water head is 4.7m, the orifice width is 6.0m, the orifice height is 4.7m, and the panel curvature radius is 6.0m.

[0092]

[0093]

[0094]

[0095]

[0096]

[0097] The top and bottom main beams are symmetrically distributed about the water pressure center line. The arc length between the main beam and the center water pressure line is The principle for selecting the hinge model is that the hinge bearing capacity is greater than 1.5 times the water pressure, so the initial hinge model is "60t", and the expression of its opening and closing force is as follows:

[0098] Therefore, the initial selection of the hoist model Type winch type hoist.

[0099] Determine the number of longitudinal beams and the cross-sectional dimensions of the longitudinal beams based on the gate size. The specific method is as follows: The width of the orifice is less than 10m, and this gate is arranged with 4 longitudinal beams. The thickness of the longitudinal beam web is 10mm. The depth of the orifice is less than 6m, the width of the longitudinal beam flange is 200mm, and the thickness of the flange is 10mm.

[0100] Initially determine the location distribution and cross-sectional information of the secondary beam. The specific method is as follows: The distance between the top secondary beam and the top of the gate, and between the top secondary beam and the bottom of the gate is 100mm, and the cross section of the secondary beam is initially determined to be No. 14 I-beam. The distance between the bottom secondary beam and the bottom main beam is 320mm, so no additional longitudinal beam is arranged between the bottom secondary beam and the bottom main beam. The distance between the bottom main beam and the top main beam is 2470mm, and 3 secondary beams are arranged in the middle, with the distance between the secondary beams being 450mm, 550mm and 650mm. The distance between the top main beam and the top secondary beam is 1950mm, and 1 secondary beam is arranged in the middle, and the distance between the secondary beam and the top main beam is 850mm.

[0101] Based on the determined positions of the primary and secondary beams, the minimum panel thickness is calculated as follows:

[0102] The calculated minimum panel thickness is much smaller than the specified maximum value (16 mm), so there is no need to adjust the number and spacing of secondary beams.

[0103] The secondary beam is checked based on the design parameters, and the calculation results are as follows:

[0104]

[0105]

[0106]

[0107] It can be seen from the calculation results that all the secondary beam checks have passed. Therefore, the use of No. 14 I-beam as the secondary beam for this gate can meet the engineering design requirements.

[0108] After the secondary beam check is completed, the internal force calculation of the main frame is carried out, and the calculation results are as follows:

The web width of the main beam is initially determined to be 400mm, and the web width of the arm is 280mm.

[0117] After the cross-sectional dimensions of the main beam and the support arm are initially determined, the main frame is checked. The checking process is as follows:

[0118]

[0119]

[0120]

[0121]

[0122]

[0123] It can be seen from the calculation results that the main frame has passed the verification, so the cross-sectional dimensions of the main beam and main support arm are no longer adjusted.

[0124] After the cross-section design of the main beam and main arm is completed, the arm chord and web members are designed based on the stability calculation formula outside the arm action plane. The stability calculation process outside the arm action plane is as follows:

[0125] It can be seen from the calculation results that the out-of-plane stability verification has passed and this gate does not require additional arm chords.

[0126] After the arm design is completed, the lifting lug design is carried out. The specific method is as follows: The initial diameter of the lifting lug hole is 80mm, the spacing between the lifting lug plates is 96mm (1.2 times the diameter of the lifting lug hole), the thickness of the lifting lug plate is 20mm, and the outer radius of the lifting lug hole is 100mm (2.5 times the radius of the lifting lug hole). Based on the initial parameters, the lifting lug is checked, and the calculation process is as follows:

[0127]

[0128]

[0129]

[0130] The lifting lug verification is passed, and there is no need to increase the initial parameters. After determining the basic design parameters of the lifting lug, update other parameters of the lifting lug: the length of the lifting lug pad is 400mm; the width of the lifting lug pad is 300mm; the pad thickness is equal to 20mm; the center height of the lifting lug hole is 200mm; the height of the lifting lug stiffener is 100mm; the thickness of the lifting lug stiffener is 10mm; the spacing between the lifting lug stiffeners is 200mm.

[0131] After the lifting lug design is completed, verify whether the initially selected support hinge model meets the requirements. The support hinge verification process is as follows:

[0132]

[0133]

[0134]

[0135] From the verification results, it can be seen that the initially selected support hinge model meets the use requirements and no adjustment is required.

[0136] After the hinge check is completed, check whether the hoist model meets the requirements. The calculation formula for the hoist force is as follows:

[0137]

[0138] It can be seen from the calculation results that the initially selected gate hoist model meets the use requirements and no adjustment is required.

[0139] Input the calculated design parameters into the automatic modeling script of the double-arm main beam gate at the same time, and sequentially establish the gate panel 3D simulation object, gate main beam 3D simulation object, gate longitudinal beam 3D simulation object, gate arm 3D simulation object, and merge the simulation objects of each component into the double-arm main beam arc gate 3D simulation object, which can be seen in Figure 2 .

[0140] Therefore, the present invention takes a double-arm main beam arc-shaped metal gate as the object and proposes a design simulation method for a double-arm main beam arc-shaped metal gate. Only a small amount of basic design parameters need to be input to automatically complete the gate design through the program and output the three-dimensional simulation object of the gate, which greatly simplifies the gate design process, reduces the workload of gate designers, and has certain social and economic benefits.
