2. Experiment content
The experimental bench consists of two parts: the transmission system platform and the actuator platform. Both parts can be assembled and disassembled for mechanical system design.
On the transmission platform, the speed ratio torque efficiency of each mechanical transmission device under different working conditions can be tested and drawn in real time.
The supporting software can be used to detect the displacement of various movable components of the actuator platform. Speed and acceleration, and display the motion curve through the computer. Through the analysis of the component motion curve, we can understand the mechanism motion rules and the mechanism motion status, and then redesign and assemble the mechanism
Use supporting software to adjust the mechanism motion of the actuator platform Conduct virtual design and simulation analysis experiments. Use the software platform provided by this experimental platform to perform virtual design and motion simulation of mechanism motion. In addition to the content provided by the software, users can perform motion data processing and virtual design and motion simulation of stage rod groups by themselves. practice.
Mechanism innovation experiments in extracurricular activities use this mechanical platform to allow users to design and add components to assemble new mechanisms.
