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.

To be published on 2019-11-21 by SAE International in United States
Bus passenger safety has always been a concern considering various impacts like side impact, front impact, rollover etc. happening in real life scenarios. Various standards have been formulated for simulating these conditions and with respect to rollover, standards like ECE-R66 are being used to understand the superstructure strength. In India, we have AIS-052 (bus body code) and AIS-031 specific for bus rollover testing. AIS-119 has been published for rollover testing of sleeper coaches with modifications in the survival space creation in sleeper coaches for berths. With physical testing being more expensive, CAE simulations are being considered as vital option which also helps in design modification in a lesser time. This paper discusses the scope of numerical simulation of sleeper coach rollover using an explicit dynamic solver RADIOSS to understand the structure deformations, survival space clearances/intrusions. The paper will describe the procedure for the numerical simulation starting from the CAD development, geometry clean up, meshing techniques, element formulations, CG measurement, input deck set up till the post processing of results. In order to validate the numerical…

To be published on 2019-11-21 by SAE International in United States
Tyre Traction Trailer is a device designed to find the Peak Brake co-efficient of C2 and C3 tyre as per ECE R117. The trailer is towed by the truck and is braked suddenly to evaluate braking co-efficient of specimen tyre. It is a single wheel trailer equipped with load cell to capture tire loads (Normal and longitudinal)while braking. Traction Trailer is modelled in MSC Adams and rigid body simulation is carried out for static stability of the system. Dynamic simulations were performed to understand locking of wheels during braking. Body frame was further modelled as flex body to perform structural analysis of the frame. The paper contains stress and deformation plots of trailer Structure under various loading conditions, change in Centre of gravity, weight transfer and forces on springs during braking and cornering, plots of tractive and normal load on tyre during braking.

This paper discusses the need for Emergency Vehicle Approaching Alert System (EVAAS) and building of EVAAS components for OTT (over- the-top content), and Media providers. According to a study by the Indian Journal of Surgery in 2006, 80 per cent of road accident victims in India do not receive any emergency medical care (Ambulance) within this ‘golden hour - the first hour after a traumatic injury, when emergency treatment is most likely to be successful.’ Due to increasing population and constructions of Roads and Buildings, Emergency Vehicles are not able to reach the desired location. Hence, there is a need of an Emergency Vehicle Approaching Alert System (EVAAS) in INDIA.

These days backhoe loader have become main part of construction equipment vehicles. The main function of backhoe is to dig ditches to lay pipes and underground cable, set up foundations for buildings and create drainage systems. During these operations, many failures are observed in backhoe loader structure/parts. With the help of Accelerated structural durability testing, life of backhoe loader & its part can be estimated; through which we can understand different failure modes. The real time data was collected during various operations which includes pit digging, duck walk, ditch climbing, levelling, dozing, piling, truck loading etc. We have used software based approach to process the strain, displacement and other data collected during real time operation to create the duty cycle. The same duty cycle was simulated in the lab condition using servo hydraulic actuators. Paper will discuss the study of engineering results in terms of strain & displacement at critical joints between real time operation & simulation of same in lab.

A V2V communication protocol to avoid Blind turn accidents and accidents happen

Nowadays the sonar system is used to avoid accidents, which is not effective in case of high-speed at blind turn situation or through side crossing in high ways. That's because vehicle position is not along the line and speed is very high so sonar will not detect danger within avoidable time limits. it seems we need to develop some fast enough system to avoid these type of accidents.

Automotive industry needs to exhibit compliance of their product with respect to the Automotive Industry Standards (AIS) at government approved test agencies. CAE (Computer Aided Engineering) plays a vital role in achieving the compliance for the same. With physical testing being more expensive for design iterations, CAE simulations are being considered as vital option.

Authors: Aditi Sethi1, Sonia Nain2, Madhusudan Joshi3 Organization: 1,2,3 International Centre for Automotive Technology, Manesar Introduction: The Indian Regional Navigation Satellite System (IRNSS), with an operational name of NAVIC, is an autonomous regional satellite navigation system developed by Indian Space Research Organization (ISRO) in 2018 that provides accurate real-time positioning and timing services. It covers India and a region extending 1,500 km around it, with plans for further extension. The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radio navigation system owned by the United States government and operated by the United States Air Force, it was launched in 1978. It is a global navigation satellite system that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Objective: IRNSS is a new navigation system for India as compared to GPS which is successfully operational and accepted globally since 1978. Therefore, comparison will help us to establish that IRNSS alone is sufficient for tracking…
