| Abstract: | The barrel＇s calculation model of temperature field, thermal bending and muzzle angle in the sunlight is presented in the paper. Based on the example of a large caliber long barrel artil- lery, the gun muzzle hot flexibility and angle is computed, thermal bending experiment under con- dition of natural sunlight and environment simulation is carried out, the calculation model and its result accuracy are validated. By means of measuring the barrel top and bottom surface tempera- ture, engineering application method for rapidly obtaining bending deflection and gun muzzle angle under different environment temperature and difference in temperature of between upper and low- er surfaces is put forward. |
