Design and Analysis of an Epicyclic Gearbox for an Electric Drivetrain 6835
6834 Published By: Blue Eyes Intelligence Engineering Sciences Publication Retrieval Number: C5787098319/2019(c)BEIESP DOI:10.35940/ijrte.C5787.098319 Abstract This paper focusses on the designing and optimizing of a planetary gearbox for an FSAE formula electric car. The conventional arrangement of single or double stage reduction transmissions are bulky and uneconomical for an FSAE car because of their less power to weight ratios and high volume to weight ratios. A planetary gearbox gives a balance between weight and power transmitted. The procedure for the design was an iterative process to determine the optimum dimensions and materials for the gearbox. The method utilized the standard equations for gear calculations and computational simulations for designing and CAD modelling for various parts of the gearbox. The transmission shafts and bearings are designed using the standard force equations. The lubrication system is also selected according to established methods.

Carbon composite drivetrain components and torsion testing apparatus
The following text outlines the work completed during a final year project as part of a mechanical engineering degree. The goal of the project was to develop supporting data, testing capabilities and lightweight carbon drivetrain component designs for the Academy Racing FSAE vehicle. The project began by conducting a literature review into lightweight, carbon drivetrain components and their manufacture. Following this a torsional testing apparatus was designed and manufactured for integration into a linear Universal Testing Machine for later use in testing adhesively bonded carbon/aluminum single lap joints in torsion. A high performance 3M acrylic adhesive was selected to conduct single lap shear testing against ASTM D3165 to develop a reliable bond specification for torsional bonding with variation occurring in bond thickness and surface preparation methods. The most consistent bonding method from single lap shear testing was selected for varied profile, single lap torsion testing of 45o carbon fibre tube with 2011 T6 aluminum. Various bond lengths and outer/inner, inner/outer surface bonding configurations were selected to validate preliminary FEA testing, previous single lap shear test data and to develop sufficient information to select a final bonding specification suitable for integration with a once piece tripod CV joint adherend for later testing on an FSAE vehicle. The manufactured torsion testing apparatus performed its function with no failure and applied reliable loading to all test specimens. The modified ASTM D3165 single lap shear testing returned adhesive shear strengths significantly lower than that specified by 3M across all 24 test specimens due to peel effects however the results obtained were consistent and allowed for key trends to be identified across changing variables. The torsion testing of the final set of aluminum/carbon shafts using 3M DP8405NS adhesive demonstrated varied trends across bond length, aluminum adherend wall thickness and between outer and inner surface bonding to the carbon tube. The analysis of results suggested additional emphasis and design is required within the adhesive application stages of joint construction to achieve reliable coverage of the complete bond area on both adherends.

FSAE Electric Vehicle Cooling System Design
3 Abstract The purpose of this project was to design and implement an effective cooling system for the Formula SAE Electric Vehicle. The main components of the drivetrain of the electric vehicle are the motor and the motor controller. The cooling system was designed to cool the motor and motor controller to ensure that they operate in an optimal temperature range thus increasing drivetrain efficiency and ultimately improving vehicle performance. During the design process, an extensive heat transfer analysis of the water side and air side of a potential radiator was performed. Additionally, system resistance curves and performance curves were calculated, plotted, and utilized in the component selection process. A suitable fan and pump were selected and a radiator was designed. After determining the critical cooling components, it was necessary to place the components in effective locations within the vehicle. In addition to placing the components, attachment tabs were designed to fix the cooling system to the frame of the vehicle and to fix the fan to the radiator. An inlet duct for the radiator was also created to direct air to the radiator and improve the performance of the system. Finally, the system was manufactured and assembled on the vehicle. At the time of this report, testing has not yet begun on the vehicle, however, testing will commence shortly and any potential problems or risks will be evaluated and modifications will be performed before the vehicle is entered into competition.The purpose of this project was to design and implement an effective cooling system for the Formula SAE Electric Vehicle.

Enhanced Particle Filtering for Bearing Remaining Useful Life Prediction of Wind Turbine Drivetrain Gearboxes
Bearing is the major contributor to wind turbine gearbox failures. Accurate remaining useful life prediction for drivetrain gearboxes of wind turbines is of great importance to achieve condition based maintenance to improve the wind turbine reliability and reduce the cost of wind power. However, remaining useful life prediction is a challenging work due to the limited monitoring data and the lack of an accurate physical fault degradation model. The particle filtering method has been used for the remaining useful life prediction of wind turbine drivetrain gearboxes, but suffers from the particle impoverishment problem due to a low particle diversity, which may lead to unsatisfactory prediction results. To solve this problem, this paper proposes an enhanced particle filtering algorithm in which an adaptive neuro fuzzy inference system is designed to learn the state transition function in the fault degradation model using the fault indicator extracted from the monitoring data; a particle modification method and an improved multinomial resampling method are proposed to improve the particle diversity in the resampling process to solve the particle impoverishment problem. The enhanced particle filtering algorithm is applied successfully to predict the remaining useful life of a bearing in the drivetrain gearbox of a 2.5 MW wind turbine equipped with a doubly fed induction generator.

Design, Manufacture and Testing of an Impact Attenuator for a FSAE Car
All the vehicles need to be equipped with a safety device because for safety of the driver and passenger. The sole purpose of the project is to focus on a very important aspect of the vehicle which is the impact attenuator. This project deals with building of crash protective device for an FSAE car. The rules for the following state that the mounted device on the car device must absorb enough energy such that the driver walks away without sustaining any serious injuries and also damage to the frame is minimized. After completing an extensive research on previously done designs and physics of a collision, preliminary design concepts were formulated. These designs were further compared against each other based on the rules which are being put up by the FSAE community. The specimen was further analysed using an explicit dynamic analysis software, and the results obtained were post processed for the evaluation. Manufacturing of the product was done using some advanced manufacturing techniques like vacuum bagging, autoclave which would eventually save the cost and time and provide better finish to the product. After the software analysis part was done and after manufacturing the product, physical experiments were conducted which used the same set up as that of software. At last, the software and the physical experiment set up were compared and hence concluded.
