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.

In this paper, mold in color diamond white ASA material has been explored for front bumper grill, fender arch extension and hinge cover applications. Other than aesthetic requirements, these parts have precise fitment requirement under sun load condition in real world usage profile. Structural durability of the design was validated by virtual engineering. Part design and material combinations with better tooling design iterations were analysed by using mold flow analysis. Complete product performances were validated for predefined key test metrics such as structural durability, thermal aging, cold impact, scratch resistance, and weathering criteria. This part met required specification. This mold in color ASA material-based parts has various benefits such as environmentally friendly manufacturing by eliminating environmental issues of coating, easily recycled, and faster part production because intended color achieved in one step during molding. Also, it lowers overall production energy footprint, less scrap with no secondary painting, and lower final part cost by eliminating secondary operations.

Employing natural plant based fiber in interior automotive parts for cost & weight benefit

Vivekanandhan-Vivekanandhan Venkatesan Balaguru
  • Technical Paper
  • 2019-28-2559
To be published on 2019-11-21 by SAE International in United States
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…

Investigation of Dry Sliding Wear Behavior of AA8011 Reinforced with Zirconium Oxide and Aluminium Oxide Hybrid Composites Processed through Multi-Direction Forging

Sri Krishna College of Engg. and Tech.-Sathishkumar Kuppuraj, Soundararajan Ranganathan, Sathishkumar Aruchamy, Shanthosh Gopal
Published 2019-10-11 by SAE International in United States
The Cardinal goal of this research work is to fabricate hybrid composites of AA8011 with reinforcement particles of Zr2O3 and Al2O3 which was taken in equal (5wt%) weight percentage. The hybrid composites were cast in a square shape (50x50x50 mm size) under the optimal stir casted process parametric condition, further, it was taken for the forging process. The prepared specimens were induced for uni-direction (x), bi-direction (x and y) and multi-direction (x,y, and z) forging route and the response of microhardness of 53, 68, 81 and 96 VHN were obtained respectively due to microstructural phase changes with an even distribution of particles in the matrix. Thus, the tribological properties of prepared specimens were tested using pin-on-disc Tribometer at room temperature under dry sliding condition of load 5,10,15,20 N and by adjusting the sliding speed as 266 and 531 rpm respectively. The outcomes uncovered all the specimens that the wear rate increments with an increase in load and coefficient of friction show an increase at most extreme load conditions. Wear rate increments with increment in the…

SRM Institute Of Science And Technology-Sundar Singh Sivam Sundarlingam Paramasivam, Durai Kumaran, Krishnaswamy Saravanan, Raj Rajendran
Tishk International University-Ganesh Babu Loganathan
Published 2019-10-11 by SAE International in United States
In the details and assembly, in the range of less than 1 mm, the number of functions increases, and the demand for industrial products in which the size and characteristics of components are decreasing is increasing. Micromachining is the most basic technology for producing these small parts and components. In this study, a series of turning operations, micromachining parameters, were performed under microscopic conditions to obtain the best response for the benefit of the industry. The needle is very high. Speed (3000, 3500, 4000 rpm), pre- (20, 40, 80 μm / sec), depth of cut (0.2.0.4.0.8 μm), tool radius (0.4.08, 1, 2 mm). Surface quality, material removal rates, energy consumption, and tool wear differences for various input process variables were investigated. Once the experiment is complete, we will develop an optimization strategy for this set of input parameters to improve responsiveness using the Grey Relational Analysis (GRA) and ANOVA. Therefore, the model can create micro-process parameters to achieve the highest product accuracy and improved performance.

Automotive CAE-Devendra Sankla
Published 2019-10-11 by SAE International in United States
Vehicle safety and adherence to rules and regulation is of utmost requirement for any OEM. ECE R42 is one of the most important test criteria for a vehicle to get launched. To prove this, we shall discuss the case of Low speed impact structure construction. In this paper, we are going to demonstrate the novel design of Polymer energy absorption structure to meet the rear bumper low speed impact test and ensure proper absorption of impact energy and avoid any damage to rear lamp of the vehicle. This paper shows a perfect example of sustainability with the help of complete modular construction of the frame structure. The proposed design uses a cost-effective way of assembling the physical part by comparing with benchmarking and within the Mahindra part library. The low speed impact structure is mounted directly to BIW panels without any extra foams. These frame structure are simple in design and rigid in construction by comparing with other OEM products and within all Mahindra vehicles.The low speed impact structural member is integrated but modular at…
