Experiment content< br/> ① Four-bar mechanism, virtual design and physical mechanism assembly of crank (guide rod) rocker mechanism (crank rocker mechanism, double crank mechanism, double rocker mechanism, crank guide rod mechanism can be assembled)
② Movement of the crank Detection, rocker motion simulation and actual measurement comparative analysis
③Frame vibration detection and mechanism balance experiment
④Virtual analysis of the motion trajectory map of points on the connecting rod motion plane.
Performance features
① Four-bar mechanisms and six-bar mechanisms can be assembled simply, and motion detection and simulation of the crank and rocker can be carried out
②The length of all rod components can be adjusted steplessly
③The detection system integrates data collection and motor adjustment and control
④The test system adopts an advanced single-chip microcomputer system and uses serial port communication. The test data has high accuracy, speed, and stability
⑤The supporting software of the system is that The platform is produced and developed with rich content, including the experimental platform introduction mechanism, virtual design mechanism, motion detection mechanism, motion simulation experiment result analysis, etc. It has the characteristics of comprehensive openness
⑥The experimental results can be saved in text form and can be uploaded on the network Send online to facilitate networked experiments, allowing teachers to correct homework online.
⑦The drive motor can be steplessly adjusted to meet the different motion requirements of the experimental institution
⑧Use experimental teaching software for experimental guidance to meet the needs of open experimental teaching. It not only facilitates teachers' guidance, but also achieves the purpose of students' own hands-on operation.
Contents and features of the detection control system and teaching analysis software
① The detection control system takes a series of single-chip units as the core and is equipped with an amplification, filtering and anti-interference circuit to realize data acquisition, amplification, preliminary processing and data communication, as well as motor control, etc. Function, the system uses the serial port to realize information communication between the data collection box and the computer
②The experimental platform teaching analysis software is a development platform, including the introduction of the experimental content, the experimental video, the visual analysis of the motion parameters, the analysis of the mechanism's motion simulation experiment results, etc.
③The real-time change curve of motion parameters can be displayed
④The rod mechanism can be virtually designed and motion simulated, and the motion trajectory of any ten points on the connecting rod motion plane can be simulated at the same time
⑤The experimental results can be saved in text form and sent on the Internet, which facilitates networked experiments and allows teachers to correct homework online.
Shape and surface treatment ① Atmosphere and beautiful, physical sense, strong processing and fine processing
② Exposed metal parts are chromium-plated and other surface anti-rust treatments plus plastic spray
③The experimental platform uses channel steel as the main structure, and the transmission part All are assembled on the platform.
