一、前言随着我国社会主义建设事业的不断发展,工程技术中对于弹性材料的(质量、数量)要求越来越高。弹性模量是弹性材料的主要性能指标之一。精确地测量材料的弹性模量,对于材料研究和工程技术应用,都有着重要意义。在七五年宝鸡会议(冶金部1015会议)上提出了把我国普遍的一种测定弹性模量的简便方法一悬丝耦合横振动法进行标准化。 I. Introduction With the continuous development of the cause of socialist construction in our country, the requirements for the quality (quantity and quantity) of elastic materials in engineering and technology are getting higher and higher. Elastic modulus is one of the main performance indicators of elastic materials. Accurately measuring the elastic modulus of a material is of great significance for material research and engineering application. At the 75th Baoji Meeting (Ministry of Metallurgy, 1015), a simple method of measuring elastic modulus that is common in our country-a standard method of coupling transverse vibration was proposed.
