Description

Technical Field

[0001] The present 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 devices in water conservancy projects for controlling water flow, regulating water levels, flood discharging or water diversion. They can block or release water flow to ensure the safe operation of hydraulic structures such as reservoirs and rivers, providing reliable water flow management and regulation functions in the fields of flood control, water supply, power generation, shipping, etc., and safeguarding the safety of people's lives and property and the efficient utilization of resources.

[0003] The double - arm main beam arc - shaped 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 - discharging projects. The structure of the double - arm main beam arc - shaped gate is complex. In traditional designs, the sizes of all components are preset by experience or standards first, and designers need to carry out check calculations after the overall design is completed. If the check of a certain component does not meet the requirements, it is often necessary to redesign the entire gate structure, recalculate and check again, resulting in an overly long and repetitive gate design process.

[0004] Furthermore, Chinese Patent (CN103400002B) discloses a design simulation platform for plane gates, which includes modules such as overall gate parameters, grillage layout, panel design, grillage design, main beam design, diaphragm design, transverse connection system, side beam design interface, roller and slider design, and calculation of hoisting force and lifting lug.

[0005] Although the above - mentioned scheme can realize the design simulation of plane gates, before the simulation, it is necessary to know the size information of each component first to carry out check and adjustment. However, the size calculation of each component of the gate is cumbersome and error - prone, which still leads to an overly long gate design process. Therefore, it is impossible to automatically generate component size information, which will affect the efficiency and accuracy of gate modeling and simulation.

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

[0007] The information disclosed in this background art is only used to understand the background of the inventive concept of the present invention, so it may include information that does not constitute prior art. Summary of the Invention

[0008] In view of the above problems or one of the above problems, one object of the present invention is to provide a design and simulation method and system for a double-arm main beam arc metal gate. By constructing a scene parameter acquisition model, a gate component design model, a gate component size generation model, and a simulation gate generation model, the structural dimensions and position parameters of the gate components can be directly obtained according to the scene parameter information, and the design and simulation of the double-arm main beam arc metal gate can be completed. Therefore, it is not necessary to manually calculate the dimensions of each component of the gate, and the component size information can be automatically generated directly through the simulation model, thereby effectively shortening the time required for gate design and improving the efficiency and accuracy of gate modeling and simulation.

[0009] In view of the above problems or one of the above problems, another object of the present invention is to provide a design and simulation method and system for a double-arm main beam arc metal gate. Without inputting any gate component information, only by inputting scene parameter information, the design and modeling of the double-arm main beam arc metal gate can be completed, greatly simplifying the gate design process, effectively avoiding cumbersome calculations and repetitive work, reducing the workload of gate designers, and facilitating the popularization and use of the metal gate design and simulation scheme.

When one of the calculated values of the hinge stresses is greater than the corresponding allowable value of the hinge stress, the check fails. Adjust the initial hinge model and perform the check again;

[0159] In the present embodiment S1, first, based on the input basic parameters, calculate the magnitude of the water pressure. The input basic parameters include: bottom sill elevation , hinge support elevation , design water head , orifice width , orifice height , panel width , panel height , panel curvature radius . The calculation formula for the water pressure is as follows:

[0164]

[0165]

[0166]

[0167] Where: is the angle between the top of the gate and the horizontal plane; is the angle between the bottom of the gate and the horizontal plane; is and Sum; is the arc length of the gate panel; is the unit weight of water; is the horizontal water pressure; is the vertical water pressure; is the total water pressure; is the angle between the action line of water pressure and the horizontal plane.

[0168] After determining the center line of water pressure, the top and bottom main girders are symmetrically distributed about the center line of water pressure, and the arc length between the main girder and the center water pressure line is . At the same time, initially determine the type of hinge and the type of hoist. The selection principle of the hinge type is that the bearing capacity of the hinge is greater than 1.5 times the water pressure. The type of hoist is determined based on the magnitude of the hoisting force. The hoisting force The calculation formula is as follows:

[0169]

[0170] In this embodiment S2, the position distribution of the longitudinal beams is related to the orifice width, and its distribution rule is as follows:

[0171] When the orifice width is less than or equal to 10 m (meter), 4 longitudinal beams are arranged; when the orifice width is greater than 10 m and less than or equal to 18 m, 5 longitudinal beams are arranged; when the orifice width is greater than 18 m and less than or equal to 24 m, 6 longitudinal beams are arranged. The web thickness of the longitudinal beam is taken as 10 mm (millimeter).

[0172] The determination method of the flange width and flange thickness of the longitudinal beam is as follows:

[0173] When the orifice depth is less than or equal to 6 m, the flange width of the longitudinal beam is taken as 200 mm, and the flange thickness is taken as 10 mm; when the orifice depth is greater than 6 m and less than 10 m, the flange width of the longitudinal beam is taken as 250 mm, and the flange thickness is taken as 12 mm; when the orifice depth is greater than 10 m and less than 14 m, the flange width of the longitudinal beam is taken as 300 mm, and the flange thickness is taken as 14 mm; when the orifice depth is greater than 14 m and less than 18 m, the flange width of the longitudinal beam is taken as 350 mm, and the flange thickness is taken as 16 mm; when the orifice depth is greater than 18 m and less than 22 m, the flange width of the longitudinal beam is taken as 400 mm, and the flange thickness is taken as 20 mm.

[0174] In this embodiment S3, it is necessary to initially determine the position distribution and section information of the secondary beams, which includes the following contents:

[0175] The distances between the top secondary beam and the top of the gate, and between the top secondary beam and the bottom of the gate are taken as 100 mm, and the cross-section of the secondary beam is initially determined as No. 14 I-beam. The initial determination principle of the position distribution of the middle secondary beams is:

[0176] The average spacing between the secondary bottom beams and the main bottom beam is about 500 mm. The spacing from the secondary bottom beam to the secondary top beam approximately follows an arithmetic progression with a common difference of 50 mm. The average spacing between the secondary beams between the main bottom beam and the main top beam is about 800 mm. The spacing from the main bottom beam to the secondary top beam approximately follows an arithmetic progression with a common difference of 100 mm. The average spacing between the main top beam and the secondary top beam is about 1200 mm. The spacing from the main top beam to the secondary top beam approximately follows an arithmetic progression with a common difference of 200 mm.

[0177] Considering the principle of economy, the thickness of the gate panel is controlled to be less than 16 mm, that is, the thickness threshold of the panel is 16 mm. Calculate the panel thickness in each grid. When the calculated panel thickness in a certain grid is greater than 16 mm, the number of secondary beams in the corresponding area is increased by 1, and the panel thickness is recalculated. For example: when the calculated panel thickness in a certain grid between the main top beam and the main bottom beam is greater than 16 mm, the number of secondary beams between the main top beam and the main bottom beam is increased by 1, and the secondary beam spacing is redetermined in the form of an arithmetic progression. The panel thickness calculation formula is as follows:

[0180] After the position of the secondary beam is determined, the secondary beam check calculation is carried out. When the secondary beam check calculation fails, increase the section model of the secondary beam and recheck. For example: when the initially selected secondary beam model is No. 14 I-beam and the secondary beam check fails, increase the secondary beam model to No. 16 and recheck. The secondary beam check calculation formula is as follows:

The thickness of the front flange of the main beam is fixed at 30 mm, the thickness of the web of the main beam is fixed at 10 mm, and the width of the flange of the support arm is the same as the width of the rear flange of the main beam. The width of the web of the main beam is initially set as (orifice depth / 10), and the width of the web of the support arm is (0.7 * width of the web of the main beam).

[0198] After initially determining the cross-sectional dimensions of the main beam and the support arm, check and adjust the cross-sectional dimensions of the main frame structure. The specific process is as follows: Based on the initially determined cross-sectional dimension parameters, calculate the bending stress at the mid-span section of the main beam, the bending stress at the support section, the shear stress at the support section, the equivalent stress of the local bending of the panel and the overall bending of the main beam, and the stress for calculating the stability within the plane of the bending moment. When any stress calculation value is greater than the allowable value, increase the width of the web of the main beam, and at the same time update the width of the web of the support arm and recalculate. The calculation formulas are as follows:

[0229] In this embodiment S6, the design parameters obtained in S1 - S5 are simultaneously input into the automated modeling script of the double - arm main girder gate. The script will successively establish three - dimensional simulation objects of the gate panel, the gate main girder, the gate longitudinal girder, and the gate arm, and then merge the simulation objects of each component into a three - dimensional simulation object of the double - arm main girder radial gate.

[0230] In this embodiment, a process of designing, checking, and adjusting by component is adopted. Each component is independently designed and checked, avoiding large - scale adjustments after the overall design is completed, and greatly improving the design efficiency. At the same time, this method can be automated through programming. Designers only need to input a small number of basic parameters such as the bottom sill elevation, hinge elevation, design head, orifice width, and orifice height, etc., to complete the design of the entire double - arm main girder radial gate and can automatically generate a three - dimensional simulation object of the gate.

[0231] A specific embodiment of applying the present invention to design and simulate the double - arm main girder radial gate of a certain discharge hole:

[0232] A certain discharge hole adopts a double - arm main girder radial gate, and the basic design parameters are as follows:

[0233] The bottom sill elevation is 83.955m, the hinge elevation is 87.455m, the design head is 4.7m, the orifice width is 6.0m, the orifice height is 4.7m, and the panel radius of curvature is 6.0m.

[0234] The method of applying the present invention to design and simulate the double - arm main girder radial gate of this discharge hole is as follows:

[0235] First, based on the input basic parameters, calculate the magnitude of the water pressure. The calculation process is as follows:

[0236]

[0237]

[0238]

[0239]

[0240]

[0241]

[0242]

[0243] The top and bottom main girders are symmetrically distributed about the center line of the water pressure, and the arc length between the main girder and the central water pressure line is . The selection principle of the hinge type is that the bearing capacity of the hinge is greater than 1.5 times the water pressure. Therefore, the initial selected hinge type is the "60t" type, and the expression of its opening and closing force is as follows:

[0244]

[0245] Therefore, the initial selection of the hoist type is type winch hoist.

[0246] Based on the gate size, determine the number and cross-sectional dimensions of the longitudinal girders. The specific method is as follows:

[0247] When the orifice width is less than 10m, 4 longitudinal girders are arranged for this gate. The thickness of the longitudinal girder web is taken as 10mm. When the orifice depth is less than 6m, the flange width of the longitudinal girder is taken as 200mm, and the flange thickness is taken as 10mm.

[0248] Preliminarily determine the position distribution and cross-sectional information of the secondary girders. The specific method is as follows:

[0249] The distances between the top secondary girder and the top of the gate, and between the top secondary girder and the bottom of the gate are taken as 100mm. The cross-section of the secondary girder is initially determined as No. 14 I-beam. The distance between the bottom secondary girder and the bottom main girder is 320mm. Therefore, no additional longitudinal girders are arranged between the bottom secondary girder and the bottom main girder. The distance between the bottom main girder and the top main girder is 2470mm, and 3 secondary girders are arranged in the middle, with the secondary girder spacings being 450mm, 550mm, and 650mm. The distance between the top main girder and the top secondary girder is 1950mm, and 1 secondary girder is arranged in the middle, with the distance between the secondary girder and the top main girder being 850mm.

[0250] Based on the determined positions of the main and secondary girders, calculate the minimum panel thickness as follows:

[0251]

[0252] The calculation result of the minimum panel thickness is much smaller than the specified maximum value (16mm). Therefore, it is not necessary to adjust the number and spacing of the secondary girders.

[0253] Check the secondary beam based on the design parameters, and the check calculation results are as follows:

[0254]

[0255]

[0256]

[0257]

[0258] It can be seen from the calculation results that all the checks of the secondary beam are passed. Therefore, selecting No. 14 I-beam as the secondary beam for this gate can meet the engineering design requirements.

[0259] After the check of the secondary beam is completed, calculate the internal forces of the main frame, and the calculation results are as follows:

[0260]

[0261]

[0262]

[0263]

[0264]

[0265]

[0266]

[0267]

[0268] After the calculation of the internal forces of the main frame is completed, determine the parameters such as the width of the front flange of the main beam, the thickness of the front flange of the main beam, the thickness of the web of the main beam, the width of the rear flange of the main beam, the thickness of the rear flange of the main beam, the width of the flange of the support arm, the thickness of the flange of the support arm, and the thickness of the web of the support arm according to the orifice size, as follows: The width of the front flange of the main beam is taken as 100m, the width of the rear flange of the main beam is taken as 260mm, the thickness of the flange of the support arm is 10mm, the thickness of the web of the support arm is 10mm, the thickness of the front flange of the main beam is 30mm, the thickness of the web of the main beam is 10mm, and the width of the flange of the support arm is taken as 260mm. The width of the web of the main beam is initially set to 400mm, and the width of the web of the support arm is initially set to 280mm.

[0269] After initially determining the cross-sectional dimensions of the main beam and the support arm, conduct the check of the main frame. The check process is as follows:

[0270]

[0271]

[0272]

[0273]

[0274]

[0275]

[0276] From the calculation results, it can be seen that the main frame checks are all passed, so there is no need to adjust the cross-sectional dimensions of the main beam and the main boom.

[0277] After the cross-section design of the main beam and the main boom is completed, the chord and web members of the boom are designed based on the out-of-plane stability checking formula of the boom. The out-of-plane stability checking process of the boom is as follows:

[0278]

[0279] From the calculation results, it can be seen that the out-of-plane stability check is passed, and there is no need to additionally arrange the chord members of the boom for this gate.

[0280] After the boom design is completed, the lug design is carried out. The specific method is as follows:

[0281] The initial diameter of the lug hole is set to 80 mm, the distance between the lug plates is 96 mm (1.2 times the diameter of the lug hole), the thickness of the lug plate is 20 mm, and the outer radius of the lug hole is 100 mm (2.5 times the radius of the lug hole). Based on the initial parameters, the lug check is carried out. The check calculation process is as follows:

[0282]

[0283]

[0284]

[0285]

[0286] The lug check is passed, and there is no need to increase the initial parameters. After determining the basic design parameters of the lug, other parameters of the lug are updated: the length of the lug backing plate is 400 mm; the width of the lug backing plate is 300 mm; the thickness of the backing plate is equal to 20 mm; the center height of the lug hole is 200 mm; the height of the lug stiffener is 100 mm; the thickness of the lug stiffener is 10 mm; the distance between the lug stiffeners is 200 mm.

[0287] After the lug design is completed, check whether the initially selected hinge model meets the requirements. The hinge check process is as follows:

[0288]

[0289]

[0290]

[0291]

[0292] It can be seen from the verification result that the initially selected hinge type meets the usage requirements and no adjustment is required.

[0293] After the hinge verification is completed, check whether the selected hoist model meets the requirements. The formula for the hoisting force is as follows:

[0294]

[0295]

[0296] It can be seen from the calculation result that the initially selected hoist model meets the usage requirements and no adjustment is required.

[0297] Input the calculated design parameters into the automated modeling script of the double-boom main girder radial gate at the same time, and successively establish the three-dimensional simulation objects of the gate panel, the gate main girder, the gate longitudinal girder, and the gate boom. Combine the simulation objects of each component into a three-dimensional simulation object of the double-boom main girder radial gate. For details, see Figure 2 .
