SL-JGD type mechanical system innovative design and overlapping test bench

An introduction to the experimental bench
The main function of the experimental bench is to provide students with a training platform for manually assembling complex mechanical systems, allowing students to design and assemble complex mechanical 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 characteristics of moving components in different complex mechanical systems through the movement parameter change curves.

Three performance characteristics
The installation platform is made of standard grooved aluminum alloy profiles. The distance between the movable supports can be adjusted arbitrarily. The overlap is flexible and maneuverable. It can be assembled with a fixed-axis gear train driven by a belt drive chain. Various types of complex mechanical systems are assembled from epicyclic gear trains, planar connecting rods and other mechanisms. There are more than a variety of typical assembly solutions. In addition, students can design their own components and assemble innovative works.
The overlapping experiment of the fixed-axis gear train and the epicyclic gear train adopts the gray proposition method. Many parameters such as the number of gear teeth and center distance of the transmission ratio are determined according to the actual situation, which greatly brings into play the initiative and innovative spirit of the students.
All gears are supported by polished rods and fixed with set screws, making adjustment easy and quick, so the overlapping speed is fast.
The length of all rod components and the eccentricity of the slider can be adjusted steplessly. Analyze the impact of changes in this parameter on the motion characteristics of the mechanism.
The detection 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 platform 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 driving DC motor can perform stepless speed adjustment to meet the different motion requirements of the experimental mechanism.
