一、七院杭州应用声学研究所俞宏沛的《计及应力螺杆的超声组件的设计》一文,对计及应力螺杆的超声组件(即超声换能器、各型变幅杆和工具头的任意组合),建立了它的一维振动数学模型。以实例说明它的应用,并且与实测结果比较,证明了该计算程序对工程上超声组件的设计是十分灵活而又方便的,引起与会代表极大兴趣。会议专门抽出一个晚上,请俞宏沛同志作了详细地论述与编程计算表演。 二、超声分科学会主任委员林冲茂教授在会议总结时强调指出:这次会议开得十分紧凑、活跃,学术气
One, seven homes Hangzhou Institute of Applied Acoustics Yu Hongpei “stress screw design of the ultrasonic component,” a text, the stress of the screw components of the ultrasound (ie ultrasonic transducer, horn and any combination of various tools ), Established its one-dimensional vibration mathematical model. An example is given to illustrate its application, and compared with the measured results, it proves that the calculation program is very flexible and convenient for the design of the engineering ultrasonic components, which is of great interest to delegates. The meeting devoted one night, please Comrade Yu Hongpei made a detailed discussion and programming calculation performance. Second, Professor Lin Chongmao, director of the Ultrasonic Branch Society, stressed at the conference’s summary: The meeting was very compact, active and academic
