Abstract

To date, many finite element neck models suitable for the European-American population have been proposed to study neck impact injury mechanisms. However, the issue that a Chinese neck model can be obtained using the geometrical scaling of a western model is highly controversial. A Chinese neck model, based on MRI/CT scan images and frozen slice images from a 35-year old male cadaver, was established in this paper to examine the geometrical difference between Chinese and European-American cervical vertebrae. Results showed that at every level of all cervical vertebrae except C2, an evident difference between the geometrical model of the Chinese and European-American cervical vertebrae was revealed. In summary, it is necessary to apply the actual anatomic parameters of the Chinese neck rather than the scaled geometry of the European-American neck to establish a standard mid-size Chinese neck finite element model. DOI: http://dx.doi.org/10.11591/telkomnika.v10i8.1616

Abstract

A unique motor drive unit (MDU) and motorcycle crash simulation unit (MCSU) were developed to establish a short-track and high-accuracy experiment system of motorcycle impact injury. The control hardware of the MDU consists of a “two DC motors” system and a “two drums, closed-loop, friction transmission” system, and the control software of the MDU has a novel “carriage acceleration profile control program” which was specially set up to prevent the cusp-like pulse and oscillation phenomenon in the acceleration stage close to the uniform velocity. The unique motorcycle sled and energy absorber constitute a novel MCSU. Research results show that: (1)Using a unique generation algorithm of the carriage acceleration- and velocity-time curve and unique manufacturing techniques of hardware components, the apparatus presented in this paper has a potential to become the first short-track experiment system of motorcycle impact injury. (2)Due to a high weight capacity with the ability to propel whole vehicles, the MDU can be used in the full motorcycle/full vehicle crash tests or vehicle component sled impact tests. DOI: http://dx.doi.org/10.11591/telkomnika.v11i4.2429
