High-temperature endurance testing machine and method for improving testing accuracy

The invention discloses a high-temperature endurance testing machine and a method for improving the testing accuracy. The high-temperature endurance testing machine comprises a calorstat for providing a specified temperature environment to a test, and a force transferring lever, wherein the outer end of the force transferring lever is used for hanging a weight, the inner end of the force transferring lever is connected with an upper pull rod, and the upper pull rod is hung in the calorstat and used for hanging one group of test samples which are serially connected together. The high-temperature endurance testing machine is characterized in that a balance regulating device used for regulating the horizontal balance of the lever is arranged on the force transferring lever. According to the high-temperature endurance testing machine and the method for improving the testing accuracy, the problem of the prior art is solved, and the accuracy of detection can be ensured when the integral weight is reduced and the qu
