Abstract: Through the comprehensive optimization design of high temperature heating furnace, high temperature fixture, the method of loading/unloading and leveling, data testing system of the conventional mechanical stress rupture and creep testing machine, the testing ability and the level of testing technique are improved, as well as the testing cost is reduced. Because a load sensor is connected at the end of the pull rod of the testing machine, the weight loading error is effectively prevented, and the traceability inquiry of loading weight is realized, meanwhile the reliability of the test data is improved.
