Automotive returnable cases (Stacktainers) are being used to transport the automotive parts through surface & seaways. No automotive manufacturer wants to spend money on woods, paper & cardboard again and again, it`s better to pay once for robust & reusable cases. these provide better protection to parts from its manufacturing to assembly line of vehicle. While transporting, any kind of crack or failure of returnable cases may lead to loss of money, human & time. To ensure the safety, these pallets have to be validated for vibrations coming from surface irregularities, sea waves & load due to stacking of cases one above other. The objective of this study is to establish a correlation in between the physical testing & simulation in Computer added Engineering (CAE) of automotive returnable case (Stacktainers). There are different types of tests considered to validate the returnable case, rough road evaluation, Multi-axial Vibration & strength evaluation. After conducting the physical test & CAE simulation, a correlation & confidence level up to 90% is established.

Objective Automotive sector is rapidly moving towards electric vehicle. BLDC motor is gaining popularity in the field of electric vehicle due to its high torque to weight ratio and simple control. In this paper we will focus on Switching loss characterization of 3 kW GaN based BLDC drive for electric vehicle. To improve efficiency of drive gallium-nitride based power transistor is used instead of Si MOSFET. GaN devices enable the design of inverter at higher frequencies with improved power density and efficiency as compared to traditional Si MOSFETs. Methodology In this paper commercially available GaN devices compared with Si MOSFETs. The power devices, which are selected for the performance comparison, are EPC2022 GaN by EPC, GS61008P GaN by Gan System and SiDR668DP Si MOSFET by Vishay. The Switching losses analytically predicted in MATHCAD tool and then compared with SPICE simulation losses. Double pulse test circuit is used to find out power losses of power transistors. This double pulse test carried out for two different GaN devices from two manufacturers and one traditional Si mosfet device…

To be published on 2019-11-21 by SAE International in United States
Abstract:At present there are a few types of transmission system available in automated industry, there might some variation in transmission system but the basic working and principle is still the same. Many big automotive manufacturers use different technologies in their transmission system but they still use the same basic principle in their transmission systems. This new technology which is brought by Koenigsegg has changed the way people think about transmission system. This new transmission system is known as Koenigsegg Direct Drive and is currently used by one automotive manufacturer and in one vehicle only, but it soon might change the way it is now.

This paper investigates and proposes the possibilities of standardizing the software/firmware package format and flash jobs in order to provide the possibility of productizing the update-over-the-air solution regarding on-board vehicle components and make use of it in all OEMs with minimum configuration changes and customization. The update-over-the-air solution in the automotive sector is provided by various suppliers and needs to be customized to meet various OEMs requirements. Possible Variants of OEM requirements are: • Variant 1 o Customer Portal + Backend + vehicle on-board components solution from supplier • Variant 2 o Customer Portal + Backend solution from OEM o Vehicle on-board components from supplier • Variant 3 o Backend from OEM o Customer Portal + vehicle on-board components from supplier ODX, VBF, and many other formats from OEMs include software/firmware packages. With variant 1, these different formats are converted into one supplier proprietary format and is saved in backend and understood by the vehicle on-board components for re-programming of target ECUs. With variant 2 and variant 3, these different OEM formats have to be…

The Automotive industry is in ever more need for a lesser weight car due to progressively stringent emission norms and the demand of customer to have better mileage. It can be a gargantuan challenge for automotive manufacturers to search for lesser weight material to meet both customers as well as regulatory norms. But in some cases such lower weight material can increase the cost and adding a expensive material which increases overall cost to a price sensitive market like India is not favorable. One such solution is using the indigenous plant fiber (Jute) in combination with propylene (PP) to make Interior plastics components. Jute a vegetable fiber also referred to as "the golden fiber" has high tensile strength, low extensibility and is well established in fabric, packing, agriculture, construction industries. The biodegradable Jute lesser weight & abundance (India is the leading manufacturer of the Jute) can be utilized in making automobile trim parts in India. Through this paper we will have insight of the natural fiber based plastic components the benefits (lesser weight, Less GSM…

Product Engineering organizations are committed to provide solutions with right quality and value to customers. Value improvement and efficient product improvement are key considerations for product engineering. In this paper, Author outlines the summary of Thumb Design and Optimization for Backhoe Loader. This project goal was to come up with own thumb design. The Backhoe thumb attachment was previously a Proprietary Design of the supplier which had two major limitations, limited opportunity of design improvements for resolving customer issues and higher total cost. The paper covers details about overcoming these limitations. In Backhoe loaders, for multiple variants of machines, four different thumbs are used. Small and mid-backhoe machine classes use 4-tine and 2-tine thumb depending upon customer applications. The design team targeted an external customer requirement of a more compact design and internal requirement of accelerating design improvement cycle time. To overcome these concerns, along with few more constraints, a full study of new thumb design was conducted. Key constraints included compatibility to current design, maintain tip forces, and optimize for a compact design. The…

Obsolescence Material management plays an important and vital role in today’s modern Aerospace manufacturing, Aerospace Maintenance, Repair and Overhaul industry as well as Aerospace Distributors. Aerospace vehicles have a considerable longer product life-cycle when compared to any other consumer goods like automobile and electronics industry. With the advent of new, disruptive technologies, many sources and supplies of materials including COTS and Standard catalogue parts, components and goods, which are widely used in an Aerospace manufacturing environment, are diminishing at a considerable rate and thus result in their obsolescence before the end disposal of the product life cycle. It is one of the leading causes to the sale of counterfeit and fraudulent parts and components, which can result in considerable deterioration of Quality and Cost to Customer. This technical paper emphasizes on the need for implementation of an effective Obsolescence management framework which an Aerospace company can follow through defining, deploying and sustaining Obsolescence Management through Policy, Procedures, Process and People methodology to be followed at manufacturing, maintenance and to identify proactively, notify and mitigate the…

Abstract Drive train failures are most common in wind turbines. Lots of effort has been made to improve the reliability of the gearbox but the truth is that these efforts do not provide a life time solution. Majority of failures are caused by bearing and gearbox. It also states that wind turbine gearbox failure causes the highest downtime as repair has to be done at Original Equipment Manufacturer [OEM]. This work aims to predict the failures in planetary gearbox using fault diagnosis technique and machine learning algorithms. In the proposed method the failing parts of planetary gearbox are monitored with the help of accelerometer sensor mounted on the planetary gearbox casing which will record the vibrations. A prototype has been fabricated as a miniature of single stage planetary gearbox. The vibrations of healthy gearbox, sun defect, planet defect and ring defect under loaded conditions are obtained. The signals show the performance characteristics of gearbox condition. These characteristics and their number of occurrences were plotted in a histogram graph. Predominant statistical features which represent the fault…
