SL-SJCT three-dimensional mechanism system innovative comprehensive experimental bench

An introduction to the experimental bench
The three-dimensional mechanism system can realize transmission in any direction, any form of movement, and any position transformation, and is increasingly widely used in modern mechanical systems. Therefore, if engineering colleges and universities want to achieve innovative education, it is essential for students to conduct innovative comprehensive experiments on three-dimensional mechanism systems when the teaching of "Mechanical Principles" for mechanical courses and "Fundamentals of Mechanical Design" for non-mechanical courses is coming to an end. .
The main function of this experimental bench is to provide students with a practical training platform for manually assembling three-dimensional (including two-dimensional) mechanism systems, allowing students to design and assemble three-dimensional mechanism transmission systems that can achieve different motion requirements. At the same time, the experimental platform has designed the locations for installing sensors on the main components, and is equipped with a detection system and data processing software. Students can understand the movement rules and kinematic dynamics characteristics of the moving components of different mechanisms through the movement parameter change curves.
2. Performance Characteristics
Assemble a three-dimensional (including two-dimensional) mechanism system that realizes any transmission direction, any movement form, and any position transformation.
There are more than a variety of two-dimensional and three-dimensional mechanism systems to be assembled. Many typical assembly solutions are consistent with reality, such as type engine automobile rear axle drive system, punch automatic transposition mechanism, space ball joint mechanism, etc.
The length of the rod member and the eccentricity of the slider can be adjusted steplessly. Analyze the impact of changes in these parameters on the motion characteristics of the mechanism.
The measurement system integrates data collection and motor adjustment control. The detection system adopts an advanced single-chip microcomputer system and uses serial port communication to ensure high accuracy, speed, and stability of test data.
The supporting software of the system is developed for the platform. It is rich in content, including the experimental bench introduction mechanism, virtual design mechanism, virtual motion mechanism, motion detection mechanism, motion simulation experiment result analysis, etc. It has the characteristics of comprehensive openness.
The dynamic DC motor can perform stepless speed regulation to meet the different motion requirements of the experimental mechanism.
The display panel adopts liquid crystal display, which displays stable data and is easy to operate
