Natural fibers such as coconut fiber and wood powder are mixed with metal materials such as aluminum and copper to obtain the composite characteristics of automatic motorcycle clutch pad materials. Coconut fiber and wood powder are suitable natural materials for composites and are easily obtained from waste. Natural fiber materials with metal reinforcement into composites are expected to produce materials suitable for friction materials such as clutch pads and brake pads with a good characteristic. This study aims to determine the characteristics of the coefficient of friction, wear, and hardness of NFC materials reinforced aluminum and copper powder for the performance of automatic motorcycle clutch pads. Experiments were carried out on various compositions of aluminum and copper powder. Tribometer testing was carried out to determine the friction coefficient and wear. Hardness testing using the Vickers method and testing the performance of automatic motorbikes with a chassis dyno test. The results show that the performances of the clutch pad with NFC-reinforced aluminum and copper show power and torque results that resemble the performances of genuine part materials in each operating cycle. The value of friction coefficient, wear, and hardness of this material are a value close to that of a genuine part clutch pad material. The improved performance of this material is expected to be considered in the manufacture of future clutch pads.","PeriodicalId":36133,"journal":{"name":"Automotive Experiences","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135181285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, a Proton Exchange Membrane (PEM) Fuel Cell can operate at low temperatures and produce an efficiency of around 40-60%. In this study, the performance test of the PEM Fuel Cell for power generation was carried out by supplying hydrogen gas using hydrogen from the electrolysis of the hydrogen generator with a variation of KOH catalyst solution with a concentration of 0.5 M; 1.0 M; 1.5 M; 2 M and using Ultra High Purity (UHP) hydrogen with various flow rates of 250 mL/min, 300 mL/min, 350 mL/min, 400 mL/min, 450 mL/min, and 500 mL/min. The test results showed that the output power of hydrogen produced by the electrolysis process was 10.8 W at a concentration of 1 M solutions at an input current of 20 A. The greater the concentration of the catalyst solution, the smaller the electrical power required for the electrolysis process. However, the hydrogen power supply produced by the hydrogen generator was not optimal, so it did not meet the needs of the PEM Fuel Cell. As a result, the PEM Fuel Cell could not work. Meanwhile, testing with UHP hydrogen produced the highest electrical power of 31.588 W at a flow rate of 450 mL/min with a load of 20 W. It indicates that the PEM Fuel Cell is optimal at the output power value with an efficiency of 69.80%.","PeriodicalId":36133,"journal":{"name":"Automotive Experiences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135181646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study explores the modelling vehicle front crumple zone to represent the behaviors of real crash scenario. The modelling process using Kamal approach is used to develop a precise vehicle crash model for analyzing the impact of a collision on both the vehicle and its passengers. In this study, a complex mass-spring-damper system representing the front crumple zone of an actual car is re-designed to modify the existing vehicle crash model. The gravitational search algorithm (GSA) is implemented in the simulation model's code to obtain optimized values of damping coefficient (c) and spring constant (k). The simulation results show that the deformation response of crumple zone and the deceleration response of vehicle body match the experimental results, indicating the model's accuracy. Additionally, this study investigates the effects of varying the GSA parameters' number of agents (N), the beta parameter (β), and the gravitational constant (G) to improve the model's accuracy by minimizing the root mean square error (RMSE) between model response and crash test data. The optimal GSA parameter chosen in this study were N = 50, β = 0.3, and G = 20 with the lowest RMSE of 22.3874, 22.26664, and 23.86638 respectively.","PeriodicalId":36133,"journal":{"name":"Automotive Experiences","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135182215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fact, the incidence rate is still very high despite routine testing. Standard Operating Procedures (SOP) for periodic testing must be updated to reduce the risk of possible accidents. Therefore, procedures for updating the SOP for periodic brake system testing are presented in this article. The Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA) methods were applied based on accident investigation data from the National Transportation Safety Committee (NTSC) from 2017 to 2022. FTA is used for risk identification, while FMEA is used for risk analysis to find the highest-risk failure cases. The results of our analysis showed that 13 failure cases were classified as intolerable so additional SOPs were required for each case. Finally, the results of this study provide new insights for stakeholders to revise the rules regarding periodic vehicle testing.","PeriodicalId":36133,"journal":{"name":"Automotive Experiences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135139353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the electrodeposition, five constant magnets were rotated (500 and 800 rpm) towards the bottom of the sample. To investigate deposition rate, surface morphology, phase, structure, corrosion resistance, and hardness in deposited Cu using a weighing scale, a scanning electron microscope equipped with energy dispersive spectroscopy (SEM-EDS), X-ray diffraction (XRD), potentiodynamic polarization, and hardness tester respectively. Bacterial activity was also evaluated through this research. Morphological surface observations showed that the increase in the rotational speed of the magnets during the electrodeposition process led to a smooth surface. A perfect Cu phase covers Al alloy with no oxide. The potentiodynamic polarization demonstrated by the increase in the rotating led to a shift to the more positive value of the corrosion potential. Moreover, the corrosion current also decreases with the increase in the rotating speed of the magnets. Less crystallite size promoted forming a higher hardness and inhibition zone of the Cu films.","PeriodicalId":36133,"journal":{"name":"Automotive Experiences","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135182218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They depend on the socio-economic situation, objective reasons of production nature, availability of appropriate material and technical bases, as well as effective use and competence of enterprise management. It seems relevant to establish a transport enterprise programme to increase operational efficiency. Therefore, research outlines the characteristics of the work programme (order portfolios) of car service stations in the current environment and focuses on ensuring their stability. Mathematical modelling and methods of mathematical and statistical analysis served as principal tools, although analysis, synthesis, comparison and other methodologies were also significant. The authors represent the car service station production programme as the sum of failures and faults arriving at the enterprise in random order. The results of the experimental studies underwent analysis based on probability theory and mathematical statistics, where mathematical models of the annual programme and the probabilities of its distribution in a given time interval were obtained. The authors recommend measures to optimise the production programme by ensuring uniform loading of car service station structures. It can study numerous theoretical issues during the design phase of production sites and make accurate predictions. There are theoretical methodologies based on certain results, which are suitable for the design of road transport services. One of them is a calculation of the enterprise's annual program based on a grouping of the number of vehicles coming into the site. The work brings new regard to the shape of the programmes related to car service providers.","PeriodicalId":36133,"journal":{"name":"Automotive Experiences","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135181097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
