Test and evaluation method for greases in grease-sealing rotary shaft seals

Grease-lubricated sealing systems show starved lubrication much more frequently than oil lubricated sealing systems. Different greases provide different lubricity to the sealing system. A test and evaluation method was developed that allows to assess the lubricity of different greases and to compare them with each other. The test and evaluation method consists of a test run and a subsequent analysis of the test components. The test run comprises a 24-hour speed collective and is performed on a test rig using real sealing system components. For the evaluation method, eight criteria are analysed, which are rated suitable for evaluating starved lubrication. The criteria include parameters measured during the test run, such as friction torque and temperature, as well as parameters inspected in the subsequent examination of all test components. All criteria are assessed and combined to an overall score, that allows to directly compare different greases with each other. The test and evaluation method developed reveals significant differences between 23 greases examined. Thus, the lubricity of greases in sealing systems can be analysed and compared much more quickly than in the past. Thanks to the rapid testing and focused evaluation of the relevant criteria, greases can be tested much more cost- and resource-efficiently than before.

MPEG-H Audio System for SBTVD TV 3.0 Call for Proposals

Under the name “TV 3.0 Project”, the Brazilian Terrestrial Television System Forum (SBTVD) has issued the Call for Proposals (CfP) for a next generation Brazilian digital TV system, in July 2020. The MPEG-H Audio system, based on the open international standard ISO/IEC 23008-3, has been proposed by Fraunhofer IIS, ATEME, the Digital Broadcasting Experts Group (DiBEG) and the Advanced Television Systems Committee (ATSC). This paper provides an overview of the MPEG-H Audio system and the TV 3.0 Project requirements for the audio component. The TV 3.0 Project specifies a detailed test and evaluation procedure for verifying the fulfillment of the requirements. With wide industry support, the MPEG-H Audio system brings immersive sound, advanced interactivity, and accessibility options, as well as advanced features like hybrid delivery, consistent loudness after user interaction, connectivity options for external sound devices and seamless configuration changes. The MPEG-H Audio proponents have submitted a complete production and broadcast real-time chain to the SBTVD Forum which demonstrates the most advanced features.

Comparing and Analysis of Test and Evaluation Methods for Connected Vehicle Communication Antenna System

With the development of Connected Vehicle, various of on-board applications and functions rely on stable, reliable and fast-response wireless connections furtherly, making it more urgent and widespread for vehicles to be equipped with relevant antenna systems such as positioning and communication. There are many types of vehicle antenna systems, together with a wide range of installation locations and a complex electronic environment which brings a huge challenges to the development of antenna manufacturers and the matching of automobile OEMs. In order to carry out the R&D, matching and testing of the vehicle antenna system better, various parties have proposed a multi-dimensional test and evaluation methods, but there is still a lack of horizontal evaluation between them. This paper analyses the requirements of automotive antenna system evaluation, sorts out and compares the technical paths of various common solutions, summarizes the characteristics and differences of various solutions, and provides a research foundation for further optimizing the vehicle-level antenna system test and evaluation program.
