61.1型線圖繪制型線圖設繪方法有：自行設繪法、母型改造法、系列船型方法、數(shù)學型線方法。不同的方法有不同的特征，本次設計中，參考資料中有母型船的型線圖，且母型改造法是繪制設計新船的型線圖行之有效的一種方法，故本次型線圖繪制中采用母型改造法。值得注意的是在母型改造法中，需要保持新船與母型船各要素的接近程度，如果修改量過大的話，會喪失母型船的優(yōu)良性能，得不償失。通過母型船的主尺度與新船的主尺度，可通過式（1.1）～（1.3）進行尺度間的變換（1.1）（1.2）（1.3）1）繪制橫剖面圖根據(jù)上述公式（1.1）～（1.3）[1]計算出各比例因子為：kkk新船的橫剖面圖由母型船的橫剖面圖在X、Y、Z方向坐標上分別乘以比例因子kL、kB、kd得到。由于母型船的水線間隔為2000mm，故新船橫剖面圖和縱剖面圖中的水線間隔都為2000mm。圖1.1橫剖面示意圖2）繪制半寬水線圖根據(jù)橫剖面示意圖可測量得各站線與水線和縱剖線交點的半寬值，由此可繪制出半寬水線圖如圖1.2所示圖1.2半寬水線示意圖3）縱剖面圖繪制高度方向的坐標通過在橫剖面圖測量各站線與各水線及各縱剖線交點得到，之后再測量半寬水線圖中各縱剖線與各水線交點的長度方向坐標和高度方向坐標，從而得到兩組坐標，由此可繪制出縱剖面型線圖如圖1.3所示。圖1.3縱剖線圖1.2靜水力曲線1）根據(jù)參考文獻[14]計算原理以及計算方法，計算各項靜水力性能，靜水力計算結果如表1.1和1.2所示。表1.1靜水力曲線計算結果水線號TPC(t/cm)船底線2114.584.331————21.6742000WL3158.805.1885271.385405.214.8441.00032.378接表1.14000WL3427.124.57111859.3012155.794.8572.11135.1286000WL3621.821.76618910.2519381.014.2131.18837.1448000WL3798.16-1.53526332.2426990.551.0474.26238.93110000WL3442.56-1.45533572.9734412.301.8625.28435.28612000WL3455.59-4.88940471.1341482.900.8336.25835.42014000WL3481.46-4.80347410.1848595.430.0027.24535.705表1.2靜水力曲線計算結果水線號C基線———0.496————2000WL26.353874.863287.5710.7400.9450.6180.6540.8354000WL11.355475.094351.2000.8030.9730.6950.7140.8656000WL9.015347.591409.7150.8490.9820.7390.7520.8708000WL6.805286.782470.7120.8900.9860.7720.7820.86710000WL5.354239.419501.0310.8070.9890.7870.7960.97512000WL4.599208.218525.2680.8100.9910.7910.7980.97614000WL4.084186.215550.3030.8170.9920.7940.8000.9722）靜水力曲線的繪制根據(jù)表1.1和表1.2在AutoCAD繪制出靜水力曲線如圖1.4所示。圖1.4靜水力曲線3）橫搖周期再估算利用公式（1.4）重新計算初穩(wěn)性高[15]所示。（1.4）在靜水力曲線圖中量出各載況下對應排水量的對應的吃水值d、浮心垂向坐標KB以及橫穩(wěn)心半徑BM，重心高度KG重心高在1.2.12節(jié)表1-14、表1-15中可以查得。重新計算過后的初穩(wěn)性高結果如表1.3所示。表1.3初穩(wěn)性高重新計算結果載況壓載出港19929.117.096.116.899.391.60壓載到港19881.847.076.106.869.311.65滿載出港38686.4511.194.755.048.711.08滿載到港38641.1811.184.765.048.671.13初穩(wěn)性高滿足要求。再按公式（1-36）重新估算橫搖周期，估算結果如表1.4所示。表1.4橫搖周期二次計算結果載況（m）（m）C值（s）壓載到港7.09168.460.4011壓載出港7.07168.970.4011滿載到港11.19171.250.3517滿載出港11.18171.250.3516在表1.4中壓載出港、到港的橫搖周期略小于12s對于國際航行的船舶，橫搖周期應滿足TΦ≥12s[1]。壓載出港與壓在到港的橫搖周期不滿足要求，但是因為沒有計算上層建筑的對重心高度的影響，使得重心高度偏低才使得船舶橫搖周期不滿足要求，故近似認為橫搖周期滿足國際航行船舶的要求。1.4邦榮曲線根據(jù)型值表和參考文獻[15]計算各站的橫剖面圖在水線下的橫剖面面積，計算結果如表1.5、1.6所示。橫剖面面積對基平面的靜矩則如表1.7、1.8所示。表1.5各站橫剖面圖水線以下橫剖面面積站號BL2000WL4000WL6000WL8000WL10000WL00.000.0000.0000.0000.00011.9330.50.000.0000.0000.0004.83527.41110.002.3696.24810.27619.25741.9161.50.004.64012.38420.49536.10268.30420.007.51919.81334.10856.80091.7832.50.0010.31926.82647.45078.326121.84430.0011.00337.93472.416111.863156.91640.0024.09161.661101.166144.334192.11650.0030.20375.739121.614171.239221.06760.0038.80387.582137.380187.380237.38070.0046.98996.713146.713196.713246.71380.0047.26797.267147.267197.267247.26790.0047.26997.269147.269197.269247.269100.0047.27197.271147.271197.271247.271110.0047.27397.273147.273197.273247.273120.0047.27597.275147.275197.275247.275130.0047.27797.277147.277197.277247.277140.0047.27997.279147.279197.279247.279150.0044.29394.005144.005194.005244.005160.0036.90984.512131.280181.872230.464170.0025.81966.230108.850151.798199.776180.0020.67751.48686.967125.319161.67218.50.0010.86436.74467.875100.135132.429190.006.80024.39647.51272.19996.93419.50.002.29210.83224.88940.58556.362200.000.0000.0000.0000.2940.883表1.6各站橫剖面圖水線以下橫剖面面積站號12000WL14000WL上甲板邊線上甲板邊線至梁拱038.98872.385110.293110.9480.564.788104.787145.718148.274181.166126.812169.262172.6971.5111.460157.478200.627204.8372140.202189.170232.759237.4052.5171.209221.038289.978294.9113206.578256.486291.286296.3704242.116292.116326.916332.2825271.067321.067357.867361.2346287.380337.380372.180377.5467296.713346.713381.513386.8798297.267347.267382.067387.4339297.269347.269382.069387.43510297.271347.271382.071387.43711297.273347.273382.073387.43912297.275347.275382.075387.44113297.277347.277382.077387.44314297.279347.279382.079387.44515294.005344.005378.805384.17116279.056328.352361.152368.51817246.957295.311338.198341.03418202.025241.906277.314281.40418.5164.722198.744225.643229.01519121.668148.271179.542181.92619.572.13989.572112.798111.278201.4722.0471.2775.737表1.7各站橫剖面圖水線以下橫剖面面積矩站號BL2000WL4000WL6000WL8000WL10000WL00.000.0000.0000.0000.000119.3310.50.000.0000.0000.00038.681254.76910.004.73815.51836.663101.473337.1401.50.008.28530.97572.442188.278488.10320.0011.90849.175122.266287.894628.2492.50.0015.55666.030172.313395.530792.74630.0019.19499.725275.943551.225961.16340.0036.902150.280349.071651.6411085.89650.0044.917182.142421.237770.6471219.27160.0047.962195.115444.305794.3051244.30570.0049.448198.896448.896798.8961248.89680.0050.000200.000450.000800.0001250.00090.0050.000200.000450.000800.0001250.000100.0050.000200.000450.000800.0001250.000110.0050.000200.000450.000800.0001250.000120.0050.000200.000450.000800.0001250.000130.0050.000200.000450.000800.0001250.000140.0050.000200.000450.000800.0001250.000150.0049.424198.847448.847798.8471248.847160.0046.262190.412434.075774.2181211.546170.0039.902161.644376.441691.7091105.912180.0029.010121.235301.509571.980917.15618.50.0021.728101.522260.270486.126776.769190.0011.60170.384187.486360.
