【 摘 要 】

Based on the requirement of mine acoustic wave technology for the signal generator, this paper aims to explore the key factors affecting the amplitude of the output acoustic signal of rare earth giant magnetostrictive materials (RE-GMM), including bar size, magnetic field strength and pre-stress in order to set an optimal plan based on the influence of various factors on output signal amplitude. This paper establishes a test platform for measuring the output performance of the acoustic signal generator and to test the prototype. Result verifies the correctness of the scheme.
