随着航空工业的发展,测定材料疲劳性能用的疲劳试验机的数量和品种不断增加,质量也有较大的提高。但是目前国内计量系统对其动态力的校正尚未建立一套有效的手段和方法,这在一定程度上影响了试验机研制和生产中的统一性、使用中的正确性和疲劳性能测试结果的可比性。从六十年代起,苏、美、德、英等国先后建立了动态力的校正装置和方法。国际标准化组织(ISO)也在起草这方面的标准。
With the development of the aviation industry, the number and variety of fatigue testing machines used for measuring the fatigue properties of materials are continuously increasing, and the quality is also greatly improved. However, the current domestic measurement system for dynamic force correction has not yet established an effective means and methods, which to a certain extent, affected the development of testing machine and the unity of the production, the use of the correctness and fatigue performance test results comparable Sex. From the sixties on, the Soviet Union, the United States, Germany, Britain and other countries have established a dynamic force correction devices and methods. The International Organization for Standardization (ISO) is also drafting standards in this area.
