These sessions are seeking abstracts that specifically address the development of polymeric and composite materials for automotive interiors and exteriors, powertrain components, as well as structural and non-structural applications. Focus is on design, processes, bonding and manufacturing technologies, as well as lightweighting strategies. Abstracts on the analysis of functional performance of these materials are encouraged.

As the number of peripheral components grows to accommodate ever increasing demands for functionality and performance in transmission applications, the integration of different technologies to obtain the best solution in terms of performance to a given application is considered to be the essence of system design. The behaviour of a mechatronic system is determined by the interdependencies of its components. Therefore, the design and development of mechatronic systems in transmission applications require an integral approach to deal with sub-systems and sub-processes of multiple domains, i.e. hydraulic, mechanical, magnetic, and electrical. The integration of mechatronic systems can be performed by components (hardware-integration) and by information processing (software-integration). The information processing consists of low-level and high-level feedback control, supervision and diagnosis, and general process management.

The shift quality of a transmission is one of the major factors influencing ride comfort and drivability of a vehicle. This shift quality is a function of both the transmission hardware and the software in the electronic control unit which includes both algorithms and calibrations. Because of this, the transmissions are tested in unison with the electronic control units on powertrain dynos. This is also an opportunity for the engineers to figure out preliminary calibrations for optimal performance/ride quality. The next step is to install the transmission in a prototype vehicle and have the test drivers get a 'feel' for the upshifts and downshifts under various driving conditions. This process is somewhat subjective and requires extensive testing on prototype vehicles which may not be ready when the transmission is. The approach we are presenting couples a powertrain dyno with a high-fidelity vehicle dynamics model running in real time. This enables the users to: 1.

Torque converters are an integral part of automatic transmissions and have a significant effect on vehicle performance and fuel economy and, therefore, on emissions. Modern transmission design with increasing number of gears requires the converter to fit in smaller space with comparable or improved functionality. One of the important components in the torque converter is the lockup clutch. It allows a direct connection between engine and transmission for fuel economy optimization. The clutch is designed to have enough capacity to transmit engine torque to the transmission without energy loss. At higher engine speeds clutch capacity starts to diminish. This phenomenon has been studied and analyzed using Computation Fluid Dynamics (CFD). New computational methods have been applied and determined the root cause. Extensive component geometry optimization has been conducted in order to find a solution without impacting the transmission/converter space claim.

To select transmission with flexible feature which makes itself applicable to world wide market is increasingly required instead of changing transmission types region by region concerning the market situation. Jatco has been encouraging the evolution and prevalence of CVT which essentially has high flexibility for realizing good fuel economy, and expanded its worldwide penetration. In this presentation , our new technologies of steel belt for Jatco CVT8 will be introduced. Jatco has developed completely new 28-mm belt. This belt has been developed for the Jatco CVT8 to obtain higher efficiency, a smaller size and a lighter weight. In the presentation, the key technology of the new 28-mm steel belt will be explained. The key technologies include specific shape, geometry and material.

One of the great opportunities with a dual clutch transmission is to create arbitrary launch and shift profiles, ranging from imperceptible “limousine” shifts to ferocious “F1” style shifts. This paper presents relevant launch and shift profile capabilities of dual wet clutches, enabled by a unique clutch design and software designed to realize these capabilities in a creative, robust and repeatable way. The feeling of any maneuver depends on the way torque is transferred to the wheels. In order to create the desired feeling during launch and shifting, torque profiles are carefully generated depending on the driver’s demand. The presentation provides an insight in the related ‘torque target’ generation and how it communicates with the engine and its electronic stability program

Nozzles tip Temperature (NTT) of an injector is a critical parameter for an engine as far as reliability of engine is concerned. It is required to ensure that the injectors operate under its operational limit because higher operating temperatures would result in enlargement of the nozzle spray tip, resulting in higher through flow, producing more undesirable power. This could result in failure of other components in the engine. In this paper we identify the various parameters that are critical for NTT and thereby predict the NTT by having the known input parameters. Response surface methodology and artificial neural network are used to identify the parameters, estimate the significance of each parameter and predict the NTT. Based on this analysis, even without the use of an instrumented injector NTT can be predicted at various working conditions of the vehicle on different terrains.

Abstract This paper presents simple but comprehensive modeling of the loads on the rubber sandwich-type mounts that often suspend the drum(s) in vibratory compactors or asphalt rollers. The goal of the modeling is to predict the overall performance of the rubber mount system. The modeling includes calculations to 1) identify and quantify all predictable low-frequency loads on the rubber mounts during normal vehicle operations, 2) predict the steady-state high-frequency vibration response of the drum, rubber mounts, and vehicle frame during compaction operations, 3) predict the heat generation in the rubber mounts from their hysteretic damping, and 4) predict the fatigue life and life distribution of the rubber mounts. Some typical results of the modeling are provided along with some brief criteria to assess suspension performance. Other, unpredictable suspension loads are discussed but not modeled.
