The invention provides an experiment apparatus and an experiment method for measuring the Young's modulus through a beam bending method using resonance phenomenon, and relates to an apparatus and a method for measuring the Young's modulus. In the prior art, the experiment principle of the beam bending method for the Young's modulus measurement is simple and abstract, and the adjustment of the telescope is difficult. A purpose of the present invention is to solve the problems in the prior art. According to the experiment apparatus, two vertical columns are arranged on a base, both ends of a rectangular cross-section metal beam are freely arranged on the cutter edge on the upper end of the vertical column in an across manner, a copper frame is sleeved on the metal beam, the lower end is provided with a vibration exciter, an iron block and a vibration pickup, the vibration exciter can be respectively connected to a sweep generator and a sinusoidal signal source, and the vibration pickup can be respectively connected to the sweep generator and an amplifier. According to the present invention, the sinusoidal signal is converted into the mechanical vibration by using the vibration exciter to make the metal beam spring vibrator perform the forced vibration, the approximate value of the resonant frequency is obtained through the amplitude-frequency characteristic curve of the metal beam spring vibrator by using the sweep generator, and the resonant frequency is further precisely determined by using the sinusoidal signal source and the oscilloscope so as to calculate the Young's modulus. The experiment apparatus and the experiment method of the present invention are suitable for the measurement of the Young's modulus.
