Ejection Mitigation FMVSS 226: Requirements - Testing - Development Strategies
In 2011, the U.S. legislation adopted - with the Federal Motor Vehicle Safety Standard (FMVSS) 226 - a new safety rule, which aims at reducing the risk to be thrown out of the vehicle during a car crash, especially in a rollover. The regulation calls for appropriate safety measures to secure the side windows of cars so that passengers can?t lean out further than allowed. To verify this, impactor tests are carried out on the side windows of the standing vehicle. For these tests, a new specially designed impactor has been developed. In these tests curtain airbags are usually employed as protective systems. For the tests specific requirements on the duration of the inflation of the airbag are introduced, since the impact of the impactor takes place up to 6 seconds after the ignition of the airbag. Additional retaining effects can be achieved using laminated safety glass for the side windows. However, these must be pre-damaged before testing. The seminar begins with the requirements of the new regulation. This includes demands on vehicle performance, as well as requirements for the test rig (accuracy, stability, friction etc.) and rules for the preparation and execution of the test. In the second part of the course, the testing procedure is described in detail. This includes the preparation of the test vehicle, the perforation of the side windows and the determination of the impact points. The actual implementation of the test, and the evaluation and documentation of results are also discussed. A description of the measurement equipment and practical hints on the experimental procedure complete this section. The last part of the seminar focuses on development strategies to meet the legal requirements. Here it is shown with which basic measures the performance can be improved with regard to the requirements of FMVSS 226. Finally conflicts with other safety requirements are identified and discussed.
The seminar is aimed at development, test and simulation engineers who have to deal with the requirements of FMVSS 226 and want to get a comprehensive overview on the topic.
