[0137] It can be explained that the test plan refers to a plan for sequencing the tests of tensile strength and shear strength.

[0138] The present invention solves the problems described in the background technology. By combining the performance evaluation instructions of the receiving connector, constructing an automated evaluation process covering multiple steps such as fixing the hexagonal head bolt to be evaluated, performance interaction and test parameter calculation, the performance of the hexagonal head bolt is comprehensively evaluated, and the efficiency and accuracy of the performance evaluation of the hexagonal head bolt are improved. This method significantly improves the reliability of the evaluation process through intelligent parameter calculation and real-time monitoring, and meets the strict requirements of modern industry for connector performance monitoring. First, the performance evaluation instruction of the connector is received, and the connector to be evaluated is determined according to the performance evaluation instruction. By receiving the specific performance evaluation instruction, the system can determine the hexagonal head bolt to be evaluated, which not only improves the accuracy of the evaluation process, but also can quickly adjust the evaluation object according to actual needs and application environment, thereby optimizing the configuration and use efficiency of resources and reducing test time and cost. Secondly, the hexagonal head bolt is placed in a fixing fixture and fixed. The hexagonal head bolt is fixed by using the fixing fixture to ensure stability during the test. The design of the fixing fixture enhances the safety of the test and prevents accidental displacement or damage during the test, thereby ensuring the reliability of the test results. Afterwards, when the hexagonal head bolt is successfully When fixed in the fixing fixture, the performance interaction device is started. The start of the performance interaction device makes the performance evaluation process automated, reduces the risk of errors caused by human operation, and can quickly and effectively perform the test by accurately controlling the test motor and the kinetic energy supplier, thereby improving the overall test efficiency; then, the performance evaluation instruction is parsed to obtain the tensile strength and shear strength of the hexagonal head bolt. After parsing the performance evaluation instruction, the tensile strength and shear strength are obtained, which can provide key performance indicators for performance evaluation. These data are helpful for evaluating the performance of the hexagonal head bolt; further, the test speed of the test motor and the test kinetic energy of the kinetic energy supplier are calculated according to the tensile strength and shear strength. By calculating the test speed and the test kinetic energy, the test conditions can be automatically adjusted according to actual needs, thereby ensuring the accuracy and effectiveness of the evaluation. This intelligent adjustment mechanism can improve the adaptability of the test to cope with hexagonal head bolts of different standards; finally, the actual speed and actual kinetic energy are monitored, and the test is stopped. The actual speed and actual kinetic energy are monitored in real time to ensure that the performance evaluation of the hexagonal head bolt is carried out under the set conditions, thereby avoiding test errors caused by improper operation. When the actual conditions are consistent with the preset conditions, the test is automatically stopped, thereby improving the efficiency of the performance evaluation. Therefore, the present invention can improve the efficiency of evaluating connector performance.
