Abstract
Using a new type reactor pressure vessel stud screw thread pair of pressurized water reactor as the research object,the screwing simulation test and tensile simulation test of the new type reactor pressure vessel stud screw thread pair were carried out.The test results show that the recommended values of installation parameters of new stud thread pair were as follows:The stud installation eccentricity should not be more than 0.5 mm.The stud screwing speed should not be more than 30 rad/min,the stud residual balance weight should not be more than 40 kg,and the maximum allowable rotation torque of the stud can be 90 N·m.The calculated value of the new stud residual tension length was almost consistent with measured value.The ratio of absolute tensile load and residual tensile load of new stud was about 1.22,which was in the range of engineering experience,proving the rationality of structure design of the new type reactor pressure vessel stud screw thread pair.And the maximum absolute tension length of the new stud under all conditions is 4.13 mm.关键词
