Using conventional solvers, the simulation of a complex and large system such as the automotive paint ovens can be quite time consuming - of the order of a several weeks or even months. A reduced order computational model of the oven that can predict thermal distribution quicker is useful in performing optimization studies and in directing finer design changes to the oven and the car body. This research focuses on the development of such a lumped capacitance thermal model (defined here in as the reduced order model: ROM) for predicting the heat of curing of an object that is inside an industrial oven. Essentially, the heat transfer modes are computed through a set of linear ordinary differential equations, by conceptualising the the physical object is conceptualised as a series of inter-connecting nodes that are linked by thermal resistors.

Abstract Increased demands on rare earth fossil fuels and the global warming have led to development of alternative technology vehicles. Electrical vehicle (EV) is chosen as one of the alternative technology to overcome these hindrances. In EVs the battery and the motor are the two most critical components used for generating the required power output. In this paper, work was done for selection battery technology and relevant packaging for a small car. The work done is described in four stages: i) battery selection based on literature, ii) car selection based on virtual reality (VR) study iii) battery package design, and iv) finally specification sheet was developed for an EV. Key Objectives considered for the battery selection are: i) minimal maintenance, ii) modular and scalable, iii) high energy density, iv) optimized thermal management, and v) low cost implications.

Abstract The Curtin Motorsport Team (CMT) currently utilise a 4130 alloy steel space frame chassis for their entry into the Formula SAE-A competition (FSAE). According to SolidWorks models, the current chassis has a weight of 32kg with a torsional stiffness of 744Nm/degree. Although this is an adequate system proven to be cost effective, relatively easy to manufacture and is torsionally stiff enough for a chassis in FSAE, CMT wish to investigate the feasibility of a carbon fibre monocoque chassis. The main goals of this paper are to benchmark the current space frame chassis design, and investigate feasibility of a carbon fibre monocoque, while reducing the chassis' weight, and increasing its torsional stiffness without increasing manufacture time. Preliminary modelling indicates that a transition to a half monocoque will yield a weight drop of 18kg, and a full monocoque will yield a drop of 23kg.

Abstract Suspension and chassis play a vital role in the structural performance of a Formula SAE vehicle. This paper focuses on CAE modeling and simulation study of the FSAE vehicle structure to analyze and improve its characteristics; and also the fabrication of the structure. This has been done for the current vehicle prepared according to 2014 Formula SAE rules; as part of Thapar University (TU) Formula student team - Team Fateh. The study started with Multi Body Dynamic (MBD) model building of front and rear suspension system using ADAMS/Car and Finite Element (FE) model building of space frame type chassis using HyperMesh for the current (2014) and previous (2011 and 2012) TU FSAE vehicles. The MBD model was used for carrying out kinematic analysis (suspension wheel travel) to calculate and analyze the roll centers using Design of Experiments (DOE) study.

Pallet extensions provide support for items of cargo beyond either the short or the long sides of a pallet, allowing increased volume to be achieved. The extensions are desgtned to suit the contour of wide-bodied aircraft. Each extension consists of a panel or shelf extending upwards and outboards within an envelope bounded by the ULD contour (see Figures 1, 2, 3, and 4). The panel or shelf is secured in this position by means of chains, cables, or structural members attached to the rails of the adjacent sides of the pallent edge.

Virtual casting improves powertrain design As designers continue to look for ways to cut weight and increase performance, casting simulations are helping optimize designs through faster, more accurate predictions of the casting process used to create key components. Horse racing America's pony cars are a favorite of racers and fans alike, so racing them against each other is natural. SAE 2015 World Congress Preview Tech trends and exhibitor products are highlighted. Tech trends and exhibitor products are highlighted in this special section, which features an exclusive interview with Honda R&D America's Jim Keller. Replicating the racing experience Professional driving simulators can be successfully exploited to shorten the traditional design-prototype testing-production process relative to a new racecar.

This information report provides general information for installing and tightening fluid conductors and connectors. Following these guidelines, with the consistent proper use of torque wrenches, tightening procedures and correct torque levels will result in diminishing leaks and improving service life by avoiding hose twisting, tube binding, false torque and improper joint closures. Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, this report should not be used as a "standard" nor a "specification" and the values shown should not be construed as "guaranteed" minimums, maximums or absolutes. This document is an information report to help users by gathering available information from the various connector standards and publishing the information in one source for easy retrieval and applied common usage. This information report is primarily intended for mobile/stationary industrial equipment applications.

While the newer fiber laser and solid-state lasers offer distinct advantages, it is not time to close the book on the venerable CO2 laser, especially for high-volume, precision powertrain components. An attachment from Advanced Nozzles eliminates expensive helium, making the cost-benefit ratio even better for precision CO2 welding applications.
