While the microcellular urethane is widely known in the automotive industry for its use in jounce bumpers, its use in Noise Vibration Harshness (NVH) applications is often not as well recognized. Even though there are some NVH parts in the market, rubber still dominates it. The objective of this paper is to demonstrate the material properties of MCU and their relevance for NVH applications in chassis and suspension components. It will also demonstrate the importance of package design to suit the use of the MCU material. This is especially important to not only achieve the best performance but also keep overall cost and weight under control. Several application types will be introduced with general design suggestions. A detailed design guideline for these applications is not part of this paper. Each application has a large variety of parameters to be considered in the design. They need to be selectively applied based on customer performance targets.

Abstract “Zoning” a catalytic converter involves placing higher concentrations of platinum group metals (PGM) in the inlet portion of the substrate. This is done to optimize the cost-to-performance tradeoff by increasing the reaction rate at lower temperatures while minimizing PGM usage. A potentially useful application of catalyst zoning is to improve performance using a constant PGM mass. A study was performed to assess what the optimum ratio of front to rear palladium zone length is to achieve the highest performance in vehicle emission testing. Varying the zone ratio from 1:1 to 1:9 shows a clear hydrocarbon performance optimum at a 1:5.66 (15%/85%) split. This performance optimum shows as both a minimum in FTP75 non-methane organic gas (NMOG) emissions as well as a minimum in hydrocarbon, carbon monoxide, and nitrogen oxide light-off temperature. Overall, an improvement of 18%, or 11 mg/mi of combined NMOG+NOx emissions was obtained without using additional PGM.

In this study the surface of the bodies being impacted against each other are treated with special speckled paints. A stereophotogrammetric system employing two high speed cameras tracks x,y,z coordinate values during impact. The data is then converted to transient local deformation vectors and strain tensors of the local area on the plastics component being impacted. The camera can also capture displacement vectors of an impactor, a guided or free-flight projectile. Various measurement signals on the projectile and parts are fed into signal processors. These raw data are then processed by a software, specially developed by BASF, for various output data that can be correlated with the corresponding output from the CAE (Computer Aided Engineering) simulations, such as energy during crash processes, real time history of stress and strain on the plastic components.

Many of the key issues currently affecting the passenger-car industry are impacting the commercial-vehicle industry as well. Likewise, a good many of the technologies suppliers come up with for one industry can also benefit the other. That is indeed the case with BASF and some of its material solutions that were on display at September’s IAA Commercial Vehicles show in Hannover, Germany.
