Main content and requirements

Experiment type

1

The kinematic diagram of mechanism

2

(1)Get familiar with the drawing method of kinematic diagram of mechanism.

(2)Get the correct determination of the type and location of the kinematic pairs and measure the length of each link of mechanism and choose the suitable scale.

(3)Analyze whether the mechanism has a definite motion or not.

Designing

2

Balancing of Machinery

2

The balancer rotor is balanced statically with a track-type static balancer, level, and rubber cement.Use a flash type or digital balancer to find the dynamic imbalance and phase of the test rotor, and achieve dynamic balance by increasing (or subtracting) the mass.

Operating

3

Test and Analysis the kinematic parameters of mechanism

2

Construct the testing system of the mechanical motion parameters as required. take advantage of acceleration sensor to transform its motion parameter of the measured piece to an electrical signal. Then draw the curve about the motion parameter and compare it with the theoretical curve. Last, analyze why it is different from each other.
