摘要
超声波振动下材料的力学行为不同常态。为了研究超声波振动对材料力学性能的影响，设计并研制了一套超声波振动下材料的力学性能实验装置。设计的内容包括超声波换能器、超声波变幅杆和夹具等，并对紫铜进行了拉伸实验，得到了由于超声波的存在使屈服点降低的结论。
The mechanical behavior of materials subjected to ultrasonic vibration is different from the normal. In order to investigate the effect of ultrasonic vibration on the mechanical properties of materials, a set of testing instrument under ultrasonic vibration was developed. This test set includes ultrasonic transducer, ultrasonic amplitude amplifier pole, clamps, etc. The tensile test of copper under ultrasonic vibration was performed and new yield stress was obtained.
