Human muscles are generally responded to abrupt force during a vehicle crash, which affects the human body motion significantly during the crash. However, it is very difficult to realize the response of living muscle to the crash dummy, therefore it is ignored in most cases and there are only few reports about on effects of the response of living muscle. In this paper, a new muscle activation system using the electromagnetic actuator and linear springs was developed for the response of living muscle in a crash dummy and the quasi-static characteristics of the Hill-type muscle model was realized with the proposed muscle activation system experimentally. First, the muscle activation system was designed for a typical longissimus capitis muscle, and then a control system was developed to produce the quasi-static force-length characteristics of the muscle. Then, the muscle elongation system was built using a linear motion table which is driven by a ball screw and a servo motor and the muscle elongation test was performed. The test results showed that the proposed muscle activation system generated the quasi-static force-length characteristics of the Hill-type muscle model very accurately. Hereafter, if the performance of proposed muscle activation system is improved considering the dynamic characteristics of the muscle activation system using the frequency response function, then the proposed muscle activation system can be applied to the crash dummy, and it is expected to imitate the human body motion during the crash procedure.
