  2. Since 1960s, the mechanical strength reliability and structural system reliability, whose main failure modes are fatigue and service life, has achieved a great deal of development and been applied to engineering machine, aeronautical and astronautical engineering, electric apparatus, bridges, ship, civil engineering etc. with the developing of space technology and tendency of machine towards high speed, precision, automation, one realizes the importance of mechanism reliability based on the accuracy of motion, for the errors of mechanism occurred more often than that of structure, especially in the field of aeronautical and astronautical engineering and operate system of weapon

    上個世紀60年代以來,以為主要失效模式的機械強度可靠性、結構體系可靠性研究得到了很大發展,並迅速應用於工程機械、航空航天、電器設備、橋梁、船舶、土木工程等。隨著空間技術的發展以及機械的高速精密化、自動化發展,人們逐漸認識到以機構動作參的準確可靠為主要標的可靠性問題日益突出,因為在很多機械上機構的故障多於結構的故障,尤其是在航空航天及武器操縱系統方面。由於這些機構的運轉特性,振動可靠性的研究亦佔有突出的位置。
