Design of “S” type track carbon free car based on cam mechanism

Research Article of American Journal of Engineering Research and Reviews Design of "S" type track carbon free car based on cam mechanism Xing Li1*, Zhizhe Wang1, Dachao Yang1, Jiangping Tang1, Tianlong Wang2 1College of Mechanical & Power Engineering, China Three Gorges University, Yichang, 443002, China. 2College of Civil Engineering & Architecture, China Three Gorges University, Yichang, 443002, China. Reverse part model based on motion trajectory is a common method in mechanism design. Compared with the traditional calculation method, it is simple and practical, and can simulate the reconstruction of the trajectory. In this paper, S-type carbon-free car was taken as an example. Firstly, the motion trajectory of the ideal car path was given. UG software was used to obtain the curve characteristics, established a mathematical model, and took the curve into the model to obtain the data of cam coordinate points. Then the MATLAB software was used to draw the cam contour and analyzed the feasibility of cam operation. The vehicle trajectory simulation was realized in MATLAB environment. Finally, the reasonable cam contour coordinate point data was imported into UG software to establish a 3D model of the cam, and the car track was repeatedly optimized to get the optimal cam shape. The rationality and the accuracy of the model were verified by the carbon-free car made by the scheme, and the corresponding guidance was provided for the research of others.

Development of a Health Information Exchange (HIE) system using the Unstructured Supplementary Service Data (USSD) Technology

Research Article of American Journal of Engineering Research and Reviews Development of a Health Information Exchange (HIE) system using the Unstructured Supplementary Service Data (USSD) Technology Odunayo Yewande., Adekunle, Y.A., Alao, O.D., Agbaje, M.O., Ebiesuwa Seun Department of Computer Science, Babcock University Most advanced nations have existing software systems that enforce a significant level of Health Information Exchange interoperability. A straightforward implementation or integration of the technique of such an application into the healthcare system in regions that have infrastructure challenges may not achieve the maximum result. Existing EHR interoperability solutions are primarily Web-based and are explicitly compatible to particular health standards. Resulting from this, such current technologies also need, at the very least, secure access to internet connectivity.On the other hand, several regions around the world (especially in developing countries) are characterized with bad internet accessibility, imbalanced spread of computer technology and literacy, and acute information breach.Therefore, this work aims to develop a system that allows patient records to be exchanged between health facilities given the challenge of lack of ubiquitous internet connectivity, unreliable internet access and also bridging the digital divide gap.This research will have positive impacts on different stakeholders in the health sector. Health institutions can access patients’ information evading the issue of poor or no internet connectivity. As a result of this, healthcare professionals will be able to give better and prompt treatments in cases of emergencies and avoid medical errors. Medical practitioners will also not have to deal with the communication gap or barrier when seeing a patient with low literacy level.This research would not only be of relevance to the health sector, it can also be adapted by other sectors using the USSD technology as a means of storage and retrieval of information.

Discussion on the relationship between construction safety accident and time based on the correspondence analysis model

Research Article of American Journal of Engineering Research and Reviews Discussion on the relationship between construction safety accident and time based on the correspondence analysis model Yishuai Tian1*, Boying Lv1, Botao Liu1 1College of Hydraulic & Environmental Engineering, China Three Gorges University, Yichang 443002, China. Based on the correspondence analysis model and the method of mining the cause and time of construction accidents. Using Python crawler technology to crawl 3896 data of the causes of construction safety accidents in China Construction Safety Supervision Information System from 2012 to 2018, a contingency table of various types and times of accidents in construction safety accidents was established. By using factor analysis, the relationship between Q-factor analysis and R-factor analysis in the corresponding factor analysis model was established. The model was analyzed and optimized by a special point removal method, and the convergence of the model was strengthened. Finally, the causes of construction safety accidents in the model and the time of one day and one year were calculated and drawn in the corresponding analysis chart of the two-dimensional model. Mining the relationship between them according to their relationship in the graph based on the data collection of 3896 building safety line accidents, this paper put forward the method of mining the main causes of accidents, and used SPSS platform technology to mine the accident data. The results showed that the occurrence of electric shock and drowning was closely related to August, fire and explosion were closely related to February, and poisoning and asphyxiation were closely related to January. 5-6 a.m. was closely related to fire and explosion, and vehicle injury was closely related to 8-9 p.m. To put forward prevention suggestions for construction accident prevention.

A workpiece turnover device based on aerodynamic system

Research Article of American Journal of Engineering Research and Reviews A workpiece turnover device based on aerodynamic system Zhenqian Zheng1*, Tianlong Wang2, Gang Wang1, Xing Li1 1College of Mechanical & Power Engineering, China Three Gorges University, Yichang, 443002, China. 2College of Civil Engineering & Architecture, China Three Gorges University, Yichang, 443002, China. In view of the problem of workpiece turnover on the assembly line of the factory, a machine for automatic workpiece turnover is designed, whose design directly affects the work level of the whole automatic production line. This paper discusses the mechanical structure of the workpiece turnover device in the automatic production line. The turnover of the workpiece can be realized by using the rotary cylinder drive system. The aerodynamic system of the workpiece is designed. The working principle of the aerodynamic system and the design of PLC circuit are analyzed. The results show that the turning of the workpiece can be realized by using the pneumatic system to control the movement of the mechanical device. The aerodynamic device has the advantages of simple structure, easy operation and strong practicability. Keywords: Pneumatic system; PLC workpiece turning device; Development trend ...
