Evaluation of Trl Designed Leg Protectors for a Medium-Sized Sport Motorcycle
Published May 23, 1994 by National Highway Traffic Safety Administration in United States
This paper describes results of an evaluation of prototype leg protectors designed by the Transport Research Laboratory (TRL) which meet the U.K. Draft Specification (UKDS) for motorcycle leg protectors, and which were fitted to a 500 cc sport motorcycle. Four full-scale impact tests and a series of laboratory tests and computer simulations were done in order to study the effects of different test methods and to evaluate the device. The full-scale impact tests involved: 30° glancing impacts to the side of a moving car; and offset-frontal impacts to a stationary car, using test methodologies developed by the motorcycle industry. The test results are compared with test results of TRL for the same nominal impact conditions but using different test methodologies. The full-scale and laboratory test data, when used with a previously validated model, also provided a basis for a computer simulation of this leg protector in 163 impact configurations which occur in motorcycle accidents. The test and simulation results are compared with previous results for other UKDS leg protector designs tested by the motorcycle industry.
