The influx of different hybrid and electric vehicle configurations has brought about unique NVH challenges from a variety of sources. NVH refinement is an important aspect of powertrain development and the vehicle integration process. While developing the NVH behavior of the vehicle is critical to satisfy customer expectations, it is also important to consider the influence of reduced exterior noise levels on pedestrian safety.

The sound package materials for vehicle noise control seminar provides a detail and thorough analysis of three different classes of acoustical materials – namely absorbers, barriers, and dampers, how they are different from each other, and acoustical properties that materials should possess for optimum vehicle noise control. The seminar addresses new advances in acoustical materials, primarily in absorption materials that impact the vehicle acoustics. The seminar covers ways to evaluate the acoustical performance of these materials using different test methods, including material, component, and vehicle level measurements.

The design of experiment (DoE) method and the related data based modeling have been successfully used for many years in the area of powertrain calibration and function development. Typically the models are used in a PC environment as plant models or are used in real-time applications in hardware-in-the loop systems. It is also possible to have these data based models executed real-time in embedded control systems. Usage of this methodology in powertrain controllers has not been widely adopted. Recently new algorithms have been established which ease the application of data based modeling in embedded control. For powertrain function development at Bosch, the DoE tool ASCMO from ETAS is used. A Gaussian process regression (GPR) model is the backbone of the algorithm. The possibility of executing such a GPR model in realtime on a current 32-bit powertrain multicore controller with sufficient accuracy has been investigated.

BorgWarner has a long history of developing wet clutch and hydraulic control modules for Dual Clutch Transmissions (DCT). In addition, BorgWarner has developed the complete control algorithms for DCT’s. Recently BorgWarner has developed iClutchTM, an electro-hydraulic system that actively controls the clutch in a manual transmission. It includes an add-on, fully integrated hydraulic control module and an optional wet friction clutch. The control algorithms have also been developed by adapting the DCT algorithms to the single clutch and master/slave architecture of MT’s. This presentation will discuss the development of the BorgWarner iClutchTM control algorithms and present results from prototype vehicle tests.

Finite Element Analysis (FEA) has been used by engineers as a design tool in new product development since the early 1990's. Until recently, most FEA applications have been limited to static analysis due to the cost and complexity of advanced types of analyses. Progress in the commercial FEA software and in computing hardware has now made it practical to use advanced types as an everyday design tool of design engineers. In addition, competitive pressures and quality requirements demand a more in-depth understanding of product behavior under real life loading conditions.

Brake noise is one of the highest ranked complaints of car owners. Grunts, groans, squeaks, and squeals are common descriptions of the annoying problem which brake engineers spend many hours trying to resolve. Consumer expectations and the high cost of warranty repairs are pushing the optimization of brake NVH performance. This course will provide you with an overview of the various damping mechanisms and tools for analyzing and reducing brake noise. A significant component of this course is the inclusion of case studies which will demonstrate how brake noise squeal issues have been successfully resolved.

This Engineering Academy covers a variety of vehicle noise control engineering principles and practices. Two specialty tracks are available: Vehicle Interior Noise and Powertrain Noise. While the Vehicle Interior Noise track focuses on the understanding and application of acoustical materials to optimize NVH in the passenger or operator compartment of a vehicle, the Powertrain Noise track focuses on NVH issues generated by powertrain noise sources and the design strategies to minimize them. Noise sources include engines, transmissions/transfer cases, accessories, exhaust, gears, axles, joints, and couplings.

Fatigue that is induced due to vibration is known as vibration induced fatigue. There are two approaches to evaluate this, viz., time & frequency domain. A straight forward and widely used method is rainflow counting technique in time domain. This counting algorithm is readily available and apart from the time history, it needs only one variable input (number of stress ranges). In case of longer time histories, time domain approach may consume lot of time and resource, which shifts our interest towards frequency domain methods. In frequency domain, Dirlik's method is proven to be robust and gives closer results to time domain. Since Dirlik's approach is probabilistic, there are different variables (such as stress ranges, scaling factor for RMS value to predict maximum stress etc.) to be considered for cumulative fatigue damage evaluation.

The NVH behaviour of brake systems remains a core problem of the brake industry. Many efforts have been made to achieve a better system understanding but the prediction of noise occurrence based on measurable parameters remains unsatisfying. By considering the brake pad as one key component within the brake system, different measurement methods nearly describing its material properties have been developed until today. This work analyses the correlation of all important, state of the art friction material/pad parameter measurement methods to the NVH behaviour of a specific brake system on a statistical basis. The answer to the question “does the NVH parameter for friction materials exist”? will be derived from the correlation results.
