This study proposes a solution to enhance ride safety and turn ability by integrating automatic speed reducers and a motion stabilizer, modelled using CATIA and designed from PVC material. The stabilizer is situated between the fork arms, holding a magnet, which initiates automatic braking when the magnet approaches the rim during a turn. We conducted three modes of testing, including no load and no angle, under magnetic load at zero angles, and under magnetic load at various angles in both lateral directions. Frequency data corresponding to the calculated speed was recorded using a spectrum analyzer, and we performed counterbalancing weight calculations to ensure stability. The results revealed a reduction in speed due to magnetic action. The objective was to design a setup that can be used for a safe two-wheeler ride while making a turn by reducing the speed. While it is true that the reduction in speed due to magnetic action in an Eddy current brake is an expected result, the unique contribution of our research lies in the application of this concept to enhance ride safety and turn ability in two-wheelers. This reduction in speed, although an expected outcome due to the magnetic action, was essential for improving stability and safety during turns. Future work will involve implementing this concept in a two-wheeler and conducting real-time testing while considering implementation challenges and reviewing relevant literature.</div></div>","PeriodicalId":38377,"journal":{"name":"SAE Technical Papers","volume":" 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135141151","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}

When an accident occurs, energy absorption and deformation play a vital role in the Automobile safety aspects, and also grooves and triggers are the ones included in the crash box for axial folding and uniform deformation. Here in this research paper, the energy absorption of kinetic energy and deformation parameter is going to be compared with the crash box with the groove at different thicknesses, also the groove is added through the vertical axis along with axial crush occurs. The modeling is done in Hyper mesh 2021 and the simulation and result validation in LS Dyna. The primary goal of this research project is to increase the crash box’s efficiency and enhance the crashworthiness and the passive safety of the passenger vehicle. It is also observed that the groove plays a vital role in reducing the acceleration transmitted to the surrounding area. The box sleeve with screw run through the groove first which almost absorbs 20% of impact energy and the remaining will be absorbed during full axial folding of the crash box. The rupture will happen along with the failure of the grooves when the screw moves, thus improving the energy absorption in the crash box, this kind of screw-type crash box was also easy to replace after the collision. Further, this simulation result will be compared with the crash box without a groove. The improvisation of crashworthiness in the crumple zone of the passenger car is the primary goal of this research. The research findings provide a valuable reference for the design of crash box constructions.</div></div>","PeriodicalId":38377,"journal":{"name":"SAE Technical Papers","volume":" 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135142166","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}

Aerospace applications, such as fuselages and steering columns, are well-suited for their utilization. These materials are frequently employed in automotive components, such as steering wheels and fuel tank lids, due to their notable corrosion resistance. The performance of magnesium alloy components remains unimproved by normal manufacturing methods due to the inherent characteristics of the material. This work introduces a contemporary approach to fabricating complex geometries through the utilization of Wire-Electro Discharge Machining (WEDM). The material utilized in this study was magnesium alloy. The investigation also considered the input parameters associated with the Wire Electrical Discharge Machining (WEDM) process, specifically the pulse duration and peak current. The findings of the study encompassed the material removal rate and surface roughness.

All these demands will lower the ride comfort performance of the Electric Vehicle. The objective of this work is to investigate the impact of tyre parameters on the ride comfort performance of EV’s. Tyre construction, tread compound and tyre pressure have a significant impact on the ride comfort performance. Tests like drive point mobility, modal analysis and cleat test are conducted experimentally as well as using virtual tools, the ride comfort performance of tyres is evaluated.

Biodiesel offers several key advantages, including its ready availability, environment friendly and its ability to contribute to lower carbondioxide levels in the atmosphere. An exhaust gas recirculation (EGR)-equipped Kirloskar compression ignition engine is used in this research to examine the influence of micro-explosions on the reduction of nitrogen oxides and smoke. The fuel chosen is Karanji oil methyl ester. The experiment involved varying the exhaust gas quantity in increments of 5%, ranging from 5% to 15%, as exhaust gas recirculation (EGR) is recognized as an effective technique for reducing NOx emissions. Similarly, the study also adjusted the water content, ranging from 5% to 15% in 5% increments. It has been shown that adding water to diesel fuel is an efficient and cheap way to cut down on pollution since it reduces the production of harmful nitrogen oxides (NO<sub>x</sub>) and smoke.
