ZME-I theoretical mechanics multifunctional integrated experiment table

Brief Introduction                                                                                             

ZME-I multifunctional experimental table is designed by professor Zhuang biaozhong from Zhejiang University, and produced by Hunan Jialin. Professor Zhuang’s thesis about this multifunctional experimental table was published on Mechanical and Practice magazine, this idea was first created at that time and got patent no. ZL 02 110595.2. In August 2000, this ZME-I experimental table was first shown and won good reviews in the 3^rd Conference on Dynamic Teaching Reformation in 21^st Century. After that, a lot improvements have been done.  THis table is of compact structure, reliable performance, beautiful appearance, easy-moving and durable. The main 6 dynamic experiments could been done. During experiments, students need to think and do it themselves, which would motivate their innovation consciousness and improve their ability of scientific experiment.

Experiment                                                                                                          

1. To test the stiffness and natural frequency of single-freedom vibration model.

2. To display self-excited vibration, and watch the difference among self-excited vibration, free vibration and forced vibration, and find the relations between amplitude and wind speed for self-excited vibration model.

3. The methods of calculating centre of mass: A, suspension; B,weigh

4.To compare the difference among gradual adding load, sudden adding load, impact load, polarization load, and get the curve  between stress and time.

5. To use the three line pendulum to test the cycle time of disc torsional vibration, then compared with theoretical calculated result,  and verify the moment of inertia formula: ； torsional vibration formula: .

6. To test the moment of inertia for heterogeneous project by equivalent method.
