A Scientific Review on Various Pellet Extruders Used In 3D Printing FDM Processes

Yousuf Pasha Shaik, Jens Schuster, Aarif Shaik
3D Printing is the trending technology in this generation and its usage is increasing day-by-day because it reduces cost of production. FDM (Fused Deposition Modeling) is one type of 3D printing which uses plastics in the form of wire like filament by an extruder for making 3D prints. But, by installing a pellet extruder instead of filament extruder reduces cost of printing process that is 1 kg of PLA pellets cost around 4€ while 1 kg of PLA filament cost around 22€; also, can print wide ranges ...

Study on the Calculation of 35 kV Parallel Gap Arcing Time Considering the Influence of Wind Load

Caijin Huang, Dong Wu, Zelin Ji
Wind load is the important factor influencing arc-extinguishing of arc. Establishing arc chain motion model of 35 kV parallel gap under wind load condition, the electromagnetic force, air resistance and wind force of a single arc element are analyzed by using the chain arc model. The arc motion parameters were solved. The arc anti-resistance and arc resistance are calculated; the criterion of arc extinguishing is defined; the arc burning time is calculated, and the arc burning time is obtained. ...

An Experimental Comparative Analysis of Twist Drilling, Helical Milling and Pilot Hole Machining for Large Diameters in CFRPs

Abubakar Yakubu Haruna, Gong Dong Wang
Carbon fiber-reinforced polymer (CFRP) large diameter hole drilling is certifiably not a broadly examined theme on account of their non-homogeneity and anisotropic highlights. In the scope of aerospace industrial uses of this material, thousands of holes have to be machined for purposes of assembly. The quality of this machined hole is influenced adversely by matrix grid cratering, thermal damage, spalling, surface delamination, and material debasement or fiber pullout. Among these different def...

Research on Project Teaching Method of Vehicle Dynamics under the Background of “New Engineering”

Sha Xu, Hui Guo, Huanhuan Zhang, Xintian Liu
Vehicle Dynamics is a compulsory course of vehicle engineering. At present, the teaching method is still dominated by teachers. There are some problems, such as insufficient engineering oriented teaching content, unable to mobilize students’ learning enthusiasm and so on, which cannot meet the training needs of “New Engineering” for engineers. Based on the concept of project teaching, this paper discusses the teaching content and teaching mode of Vehicle Dynamics, so as to improve students’ part...

Performance Analysis of Front Bumper under Frontal Low Speed Impact

Ying Wang
In this paper, the front bumper of a certain model was simulated and analyzed in low-speed frontal collision. HyperMesh software was used as the pre-processor, LS-DYNA was submitted for simulation calculation, and HyperView was used as the post-processor to view the output results, so as to analyze the performance of the automobile front bumper in low-speed frontal collision. At the same time, the influence of different beam thickness on collision performance is compared under the same condition...

Research on Teaching Reform of Robot Technology under the Background of New Engineering

Xingzhi Xu
To improve the training scheme of new engineering talents, a teaching reform method on training innovation-oriented talent in robot engineering is explored comprehensively. By making a deep analysis between the graduates trained by the current robotic technology courses in universities and the talents required for the construction of emerging engineering into consideration, a teaching reform strategy of “characteristic theory teaching, practical engineering teaching, diversified assessment” has ...

Design of Variable Frequency Speed Regulation and Constant Pressure Water Supply System

Hechao Liu, Yan Zhi
With the increase of population density and the improvement of human economic level, the emergence of high-rise buildings has put forward higher requirements on infrastructure such as building hydropower, traditional water supply methods have disadvantages such as secondary pollution, unstable water pressure, and high energy consumption. Therefore, variable frequency and constant pressure water supply have gradually become the main method of water supply for high-rise buildings. In order to meet...

The Contact and Transient Dynamic Analysis of Gear Meshing with ANSYS

Xing Zou, Chengwen Yang, Baolin Liu
The paper describes the dynamic characteristic and fatigue life of the gear meshing. Use the ANSYS to deal with the problem of motion errors which are the result of the wear and the curve caused by the rough surface of the gear generated by the low machining accuracy in the process. And through the analysis, the value and the changing trend of the equivalent stress, fatigue life, and fatigue sensitivity with different friction coefficients can be known. Then it provides an important theoretical ...

Performance Improvement of a Gas Turbine Power Plant in Nigeria by Exergy Analysis: A Case of Geregu 1

Mkpamdi Nelson Eke, Edmund Chijioke Okoroigwe, Sunday Ifeanyi Umeh, Peter Okonkwo
This paper presents the performance improvement study of gas turbine power plant in Nigeria by exergy analysis method using Geregu 1 gas turbine power plant as a case study. The study analyzed the system’s components separately in order to identify the sites where the largest exergy losses occur and to quantify the amount. Results of the component efficiencies based on their thermodynamic models of energy and exergy analyses at design and operating years of the power plant revealed that the maxi...
