Description

Technical Field

[0001] The present invention relates to the technical field of ship design, and in particular, to a method, system, medium and terminal for simulating and calculating the thickness of a ship's anti-floating epoxy Background Art

[0002] Liquefied petroleum gas carriers generally use special tanks to transport liquefied petroleum gas. The tank shapes are mainly spherical and diamond-shaped. Among them, the diamond-shaped liquid cargo tank (liquid tank) is connected to the hull through supports. Between the supports are laminated wood and epoxy resin in sequence. The types of supports include vertical supports, bottom anti-rolling supports, anti-tilting supports, top anti-rolling supports, and anti-floating supports. Among them, the vertical supports provide vertical support for the liquid tank, the anti-tilting supports limit the longitudinal movement of the liquid tank, the anti-rolling supports limit the lateral movement of the liquid tank, and the anti-floating supports limit the upward floating of the liquid tank in case of accidental damage to the tank. Except for the anti-floating supports, the vertical directions of the panels of other supports are all in the positive direction of the three-dimensional coordinates. The vertical direction of the anti-floating support panel forms a 45-degree angle with the Y direction. Because the vertical direction of the anti-floating support panel is not in the positive direction of the three-dimensional coordinates, simply looking at the deviation in the Y or Z single direction of the anti-floating support cannot correctly analyze the vertical deviation of the panel. It is necessary to perform Y+Z calculation, and the calculation result is the vertical deviation of the anti-floating support. Due to the particularity of the accuracy analysis method of the anti-floating support, during the deck assembly positioning, the deviation positioning personnel of the anti-floating support cannot accurately analyze on-site. Moreover, when calculating the thickness of the anti-floating epoxy of the liquid tank, the shipowner requires that the distances between the laminated wood of all the anti-floating supports of a single liquid tank and the panels of the corresponding deck anti-floating supports should be all equal. Therefore, when the deck is formed, the associated matching accuracy between the deck anti-floating supports and the liquid tank anti-floating supports is poor, and the epoxy thickness of some laminated wood exceeds the tolerance range, which requires grinding and thickness reduction treatment, greatly increasing the construction cost and also prolonging the dock period. Summary of the Invention

[0055] Embodiment 1

[0056] This embodiment provides a method for simulating and calculating the epoxy thickness for preventing a ship from floating. Referring to Figures 1 to 4 , the method includes the following steps:

[0057] S100: Collect the coordinate data of the liquid tank anti-floating supports on the ship's liquid tank and the coordinate data of the deck anti-floating supports on the ship's deck. The coordinate data includes the actual coordinates, the design coordinates, and the coordinate deviation data between the actual coordinates and the design coordinates.

[0058] After the liquid tank is installed, there is a deviation between the actual position and the designed position of the liquid tank anti-floating support 2 on the liquid tank. Therefore, it is necessary to measure the actual coordinates and the designed coordinates of the liquid tank anti-floating support 2. For example, the actual coordinates of all the liquid tank anti-floating supports 2 can be measured through the precision management software EcoBlock, and the deviation between the actual coordinates and the designed coordinates is analyzed to generate coordinate deviation data. After the measurement is completed, the software will generate a table, which records the designed coordinates, actual coordinates and coordinate deviation data of each liquid tank anti-floating support 2 on the liquid tank. Name the table containing the designed position coordinates, actual position coordinates and coordinate deviation data of each liquid tank anti-floating support 2 on the liquid tank, for example, name it as Tank No. 4.xlsx. The installation of the deck is a complex process, and the deck positioning measurement can be carried out in stages. Taking the epoxy thickness simulation calculation of the anti-floating support of Tank No. 4 of a certain liquefied petroleum gas ship as an example, for instance, the installation of the deck can be divided into three stages: 61Z-1, 61Z-2, and 61Z-3. The actual coordinates and the designed coordinates of the deck anti-floating support 1 on the deck will be measured at each stage. Similar to the liquid tank anti-floating support 2 on the liquid tank, the actual coordinates, designed coordinates and coordinate deviation data of the deck anti-floating support 1 can be measured through the precision management software EcoBlock. After the measurement is completed, the software will generate a table, which records the designed coordinates, actual coordinates and coordinate deviation data of each deck anti-floating support 1 on the deck. Name the table containing the designed position coordinates, actual position coordinates and coordinate deviation data of each deck anti-floating support 1 on the deck, for example, name it as 61Z-1.xlsx, 61Z-2.xlsx, 61Z-3.xlsx. If the measurement data of the deck anti-floating support 1 is complete, that is, it contains the data of all stages, then it is directly named as 61Z.xlsx.

[0059] S200: Calculate the vertical deck deviation A of the deck anti-floating support according to the coordinate data of the deck anti-floating support;

[0060] In an optional embodiment of the present embodiment, the deck section number, liquid tank section number, deck and liquid tank anti-floating rib position number, and the actual coordinates and designed coordinates of the deck and the liquid tank are input into an Excel table. Refer to Figure 4, continue to take the epoxy thickness simulation calculation of the anti-floating support of the No. 4 liquid tank of a liquefied petroleum gas ship as an example. The segments involved in the anti-floating support of the No. 4 liquid tank include 742, 752, 746, 756, 749, 759. The deck segments corresponding to the anti-floating support of the No. 4 liquid tank include 521, 531, 522, 532, 523, 533. The rib numbers involved are FR51, FR54, FR58, FR62, FR65, FR69, FR73, FR77, FR81, FR85, FR89, FR92. One rib number corresponds to four anti-floating supports, and there is one anti-floating support on each side of the left and right of the liquid tank and the deck. Each deck anti-floating support 1 and liquid tank anti-floating support 2 contains four corner points, and each corner point has a three-dimensional design coordinate, which is (X, Y, Z). Taking the three-dimensional design coordinate of the deck anti-floating support 1 of FR51 as an example, the X, Y, and Z values are 40739, 15171, and 19646 respectively.

[0061] Preferably, use Excel-VBA to write a calculation program that can automatically read the actual coordinates, design coordinates, and coordinate deviation data of the anti-floating supports on the liquid tank and the deck, and calculate the anti-floating epoxy thickness based on the actual coordinates, design coordinates, and coordinate deviation data of the liquid tank anti-floating support 2 and the deck anti-floating support 1. Through the calculation program, workers can quickly and accurately complete complex calculations and avoid errors caused by manual operations.

[0062] Specifically, the calculation program includes four function options, namely "Deck anti-floating data filling", "Liquid tank anti-floating data filling", "Deck anti-floating data clearing", and "Liquid tank anti-floating data clearing". After the user clicks the "Deck anti-floating data filling" option, the program will automatically read the relevant data of the deck anti-floating support 1 and fill the relevant data of the deck anti-floating support 1 into the table. After the user clicks the "Liquid tank anti-floating data filling" option, the program will automatically read the relevant data of the liquid tank anti-floating support 2 and fill the relevant data of the liquid tank anti-floating support 2 into the table. After the user clicks the "Deck anti-floating data clearing" option, the program will clear the relevant data of the deck anti-floating support 1 in the table. After the user clicks the "Liquid tank anti-floating data clearing" option, the program will clear the relevant data of the liquid tank anti-floating support 2 in the table.

[0063] Taking the 61Z deck anti-floating support as an example, click the "Deck anti-floating data filling" option, and the calculation program automatically reads the actual coordinates (X ll , Y ll , Z ll ) of the deck anti-floating support 1 of 61Z and the design coordinates (X sj , Y sj , Z sj ) and coordinate deviation data (X pc , Y pc , Zpc ) and then perform loop judgment and calculation. If |X sj −X ll | ≤ half of the longitudinal length of the deck anti-floating support 1, |Y sj −Y ll | ≤ half of the transverse width of the deck anti-floating support 1 and |Z sj −Z ll | ≤ half of the vertical height of the deck anti-floating support 1, then the deck vertical deviation A of the anti-floating support 1 on the deck = Y pc +Z pc . For example, if |X sj −X ll | ≤ 235 mm, |Y sj −Y ll | ≤ 403 mm and |Z sj −Z ll | ≤ 403 mm, then A = Y pc +Z pc .

[0064] Taking the left anti-floating of the FR51 deck as an example, the deviation value in the Y direction is -2 mm, and the deviation value in the Z direction is -4 mm. At this time, Y pc = -2 mm, Z pc = -4 mm, A = Y pc +Z pc = (-2 mm) + (-4 mm) = -6 mm. The calculation result of A will be automatically filled in the row where "(A)-left" is located in the table, for example, the column where the three-dimensional coordinates are (40739, 15171, 19646). Each anti-floating support has four corner points, namely the upper aft corner point, the lower aft corner point, the upper forward corner point, and the lower forward corner point. Workers usually measure the deviation data of at least three corner points. If the data of a certain corner point is missing, the calculation program will automatically calculate the deviation of the fourth corner point based on the existing three corner point data. The calculation formula is A1 + A4 = A2 + A3, where A1 is the deviation data of the upper aft corner point of the deck anti-floating support 1, A2 is the deviation data of the lower aft corner point of the deck anti-floating support 1, A3 is the deviation data of the upper forward corner point of the deck anti-floating support 1, and A4 is the deviation data of the lower forward corner point of the deck anti-floating support 1. Through judgment, the calculation program determines that if A1 is missing, then A1 = A2 + A3 - A4; if A2 is missing, then A2 = A1 + A4 - A3; if A3 is missing, then A3 = A1 + A4 - A2; if A4 is missing, then A4 = A2 + A3 - A1.

[0065] S300: Calculate the vertical deviation B of the liquid tank anti-floating support according to the coordinate data of the liquid tank anti-floating support;

[0066] The calculation formula of the vertical deviation B of the anti-floating support on the liquid tank is the same as the calculation formula of the vertical deviation A of the deck. First, the actual coordinates (X c , Y c , Z c ), design coordinates (X s , Y s , Z s ) and coordinate deviation data (X p , Y p , Z p ), when |X s -X c |≤half of the longitudinal length of the tank anti-floating support 2, |Y s -Y c |≤half of the transverse width of the tank anti-floating support 2 and |Z s -Z c |≤half of the vertical height of the tank anti-floating support 2, the calculation formula for the vertical deviation B of the tank is B=Y p +Z p The calculation formula of the deviation data of the corner point of the liquid tank anti-floating support 2 is B1+B4=B2+B3. Among them, B1 is the deviation data of the stern upper corner point of the liquid tank anti-floating support 2, B2 is the deviation data of the stern lower corner point of the liquid tank anti-floating support 2, B3 is the deviation data of the bow upper corner point of the liquid tank anti-floating support 2, and B4 is the deviation data of the bow lower corner point of the liquid tank anti-floating support 2.

[0067] Reference Figure 2 , take the anti-floating support on the left side of the FR51 rib number of the No. 4 liquid tank as an example, for example, a total of 3 points are measured, and the values ​​of B2, B3, and B4 are calculated to be 7mm, 6mm, and 6mm respectively. There is no measurement data for B1 at the stern position, so the formula is used to calculate B1=7mm+6mm-6mm. After the calculation is completed, the calculation result of B1 is automatically filled in the corresponding position of the table through the calculation program. So far, the vertical deviation A of the deck and the vertical deviation B of the liquid tank are automatically read, cycled, judged, calculated, and filled in through the calculation program. The table is divided into two parts, the upper part is the data on the left side of the deck and the liquid tank, and the lower part is the data on the right side of the deck and the liquid tank.

[0068] S400: Calculating the anti-floating epoxy thickness H according to the deck vertical deviation A and the liquid tank vertical deviation B.

[0069] Next, the calculation program automatically calculates the distance deviation C between the deck and the anti-floating support on the tank, and further calculates the anti-floating panel spacing G and anti-floating epoxy thickness H between the upper surface of the anti-floating laminated wood of the tank and the deck anti-floating panel. Figure 3, specifically, first calculate the distance deviation data C between the floating support of the deck and the floating support of the liquid tank. Since both the floating support panel of the deck and the floating support panel of the liquid tank are at a 45-degree angle to the Y direction, so C = (A - B) × sin45°. Taking the upper aft position on the left side of FR51 as an example, A1 is -6 mm, B1 is 7 mm, C1 = (-6 mm - 7 mm) × sin45°, and the calculated result C1 is -9 mm. Then calculate the distance G between the upper surface of the floating laminated wood of the liquid tank and the floating panel of the deck. First calculate the minimum value C Min of the distance deviation C of the floating support on the liquid tank. In this embodiment, C Min The calculation result is -10 mm. Then calculate the floating panel spacing G, G = C Min + D - E - F, where D is the theoretical spacing of the floating panel, E is the thickness of the floating laminated wood board, and F is the minimum epoxy thickness for inspection. Then calculate the floating epoxy thickness H of the liquid tank, H = C + D - E - G. D, E, and F are all set values. In this embodiment, D is 185 mm, E is 90 mm, and F is 10 mm. In this embodiment, G = -10 mm + 185 mm - 90 mm - 10 mm = 75 mm, H = -9 mm + 185 mm - 90 mm - 75 mm = 11 mm. Finally, calculate the minimum value H Min and the maximum value H Max of the floating epoxy thickness H of the liquid tank. In this embodiment, H Min is 10 mm, and H Max is 31 mm. Since the design requirement range for the floating epoxy thickness of the No. 4 liquid tank is 10 mm to 45 mm, the floating epoxy thickness of the No. 4 liquid tank meets the design requirements. Finally, input all the data used to calculate the floating epoxy thickness H into the table.

[0070] The method for simulating and calculating the floating epoxy thickness of the ship in this application further includes: formulating an adjustment plan according to the calculation result of the floating epoxy thickness to ensure that the floating epoxy thickness meets the design requirements. In S300, the minimum value H Min and the maximum value H Max of the epoxy thickness are obtained by calculation. Usually, H Min is greater than the minimum allowable value of the floating epoxy thickness H. Therefore, mainly consider whether H Max is less than the maximum allowable value of the floating epoxy thickness H. If H Max exceeds the maximum allowable value of the floating epoxy thickness H, it means that the epoxy resin is too thick, and then the floating epoxy thickness H needs to be adjusted. If the floating epoxy thickness H is unqualified, the workers will adjust according to H MaxThe difference from the maximum allowable value of the anti-floating epoxy thickness H is used to formulate an adjustment plan. After calculating the anti-floating epoxy thickness H on the liquid tank and the deck, a risk assessment is carried out on the values of the epoxy thickness that exceed the design requirements range. If the anti-floating epoxy thickness in a certain area is close to or exceeds the limit of the design requirements range of the anti-floating epoxy thickness H, a fine-tuning plan for the liquid tank and the deck needs to be given, such as moving or rotating the liquid tank as a whole, to ensure that the epoxy thickness meets the requirements.

[0071] In an alternative embodiment of this embodiment, if during the installation stage of the deck section, it is found that the anti-floating epoxy thickness H corresponding to the 521 section exceeds the maximum allowable value of the anti-floating epoxy thickness H, the workers can consider repositioning the 521 section, such as lowering the 521 section or moving it towards the middle. If there is no problem with the installation accuracy of the anti-floating support, the workers generally do not modify the anti-floating support, but solve the problem by adjusting the position of the deck section. In another alternative embodiment of this embodiment, if during the completion stage of the deck overall assembly, it is found that the anti-floating epoxy thickness H in a certain area is close to the maximum allowable value of the anti-floating epoxy thickness, the workers will, based on the overall data of the liquid tank and the deck, give priority to moving or rotating the liquid tank as a whole to reduce the risk that the anti-floating epoxy thickness H exceeds the maximum allowable value of the anti-floating epoxy thickness H.

[0072] A method for simulating and calculating the anti-floating epoxy thickness of a ship according to the present invention can efficiently calculate the anti-floating epoxy thickness H of the liquid tank during the process management of the deck overall assembly positioning. After calculating the anti-floating epoxy thickness H on the liquid tank and the deck, it provides the optimal liquid tank and deck positioning plan, so that the anti-floating epoxy thickness H of each liquid tank is adjusted within the design requirements range, facilitating subsequent construction. The method for simulating and calculating the anti-floating epoxy thickness of the ship in this application has characteristics such as foresight, intelligence, and accuracy, improving the shipbuilding level.
