摘要为了提高高频振动时效消除残余应力的效果，优化设计一种高频振动能量放大装置。采用正交实验法结合ANSYS有限元软件，以振幅放大倍数和振幅均匀性评价因子为目标函数，结构尺寸参数为设计变量，对高频振动能量放大装置进行优化设计。通过实验研究高频振动能量放大装置的应用对高频振动时效消除AISI 1045钢淬火试样残余应力的影响。结果表明：高频振动能量放大装置的振幅放大倍数可以达到7.30、振幅均匀性评价因子可以低至0.68；高频振动能量放大装置能够显著的放大电磁式激振器的输出振幅，同时能够输出相对均匀的振幅。高频振动能量放大装置的应用显著的提高了高频振动时效消除残余应力的效果。基于正交实验法结合ANSYS有限元软件进行高频振动能量放大装置的优化设计，可以减少设计方案的数目，提高设计的效率，具有一定的工程应用价值。

Abstract：In order to improve the effect of the high-frequency vibratory stress relief on eliminating residual stress, the optimization design of a high-frequency vibration energy amplifying device was carried out using the orthogonal experimental method combined with the finite element software ANSYS, by setting the amplitude amplifying factor and the evaluation factor of amplitude uniformity as objective function, and the structural dimension parameters as design variables. The experimental studies of the high-frequency vibratory stress relief on AISI 1045 steel quenched specimens were carried out to study the effectiveness of the high-frequency vibration energy amplifying device for the high-frequency vibratory stress relief. The results show that the output amplitude of the electromagnetic exciter can be obviously amplified by the high-frequency vibration energy amplifying device and the output amplitude of the high-frequency vibration energy amplifying device is relative uniformity, whose amplitude amplification factor can be up to 7.30 and the evaluation factor of amplitude uniformity can as low as 0.68. The effect of the high-frequency vibratory stress relief on eliminating residual stress can be obviously improved by the high-frequency vibration energy amplifying device. The use of the orthogonal experimental method combined with the finite element software ANSYS as a tool to reduce the simulation runs in the optimization design of the high-frequency vibration energy amplifying device can improve the design efficiency, which has definite value in engineering application.
