Acoustical Test Instrument of Mechanical Properties with Shaft Work pieces
Main discussed Mechanical Properties measurement with Shaft Work pieces, and used the method of acoustic resonance to measure Mechanical Properties such as intensity, hardness and toughness in this paper. Introduced design process of instrument for hardware and software. Development of this Instrument, it may instead of such as the universal testing machine, the hardometer and the impact-toughness tester as NDT. Derived some expressions about acousticparameters and Mechanical Properties, then design the acoustic test instrument through me sensor and electronic technology. Build NDT system that is based single chip computer. This article showed some of parameter as tensile strength, extensibility, hardness and impact-toughness, shown relation expression these parameters and acoustic testing, through computer simulation calculation and regression analysis. For example tow kinds of the shaft work pieces, give testing data and some diagram and graphed to research in circuit system. Take some analysis of the system accuracy and give out conclusion.
