一、现状和差距机械强度与振动技术是进行机械产品设计,提高机械产品及其主要零部件工作效能,使用寿命和可靠性的一项重要基础技术,它可为机械产品提供先进的计算方法和设计数据、合理选材的指导准则和依据。因此,它是从根本上提高机械产品质量和水平,并进一步打入国际市场的重要手段。近二、三十年来由于军事尖端工业的兴起,机械强度与振动技术有了迅速的发展。在民用机械工业中的许多行业如汽车、电力、石油、化工、冶金等现代化的成套设备中,也愈来愈广泛 First, the status quo and the gap Mechanical strength and vibration technology is the mechanical product design, improve mechanical products and their main components of the working efficiency, service life and reliability of an important basic technology for mechanical products can provide advanced calculation methods and Design data, guidelines and rationale for material selection. Therefore, it is an important means to fundamentally improve the quality and level of mechanical products and further penetrate the international market. In the recent two or three decades, due to the rise of military advanced industries, the mechanical strength and vibration technology have developed rapidly. In the civil machinery industry in many industries such as automotive, electric power, petroleum, chemical, metallurgy and other modern complete sets of equipment, but also more and more widely
