IMPACT DETECTION DEVICE AND IMPACT STRENGTH DETERMINATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an impact detection device having sensitivity directivity to impact and requiring no power supply. SOLUTION: The impact detection device includes a housing in which a columnar weight-moving space 10 is formed inside; a lid for covering a face of the weight-moving space; a weight 15 housed in the weight-moving space; a wight-supporting part having an outer diameter smaller than the weight; and a fluidic body 19 filled in the weight-moving space. The wight has an external shape capable of sliding in axial directions in the weight-moving space. Communicating paths communicating with one end to the other end in the axial directions are formed in the weight. Both end parts of the weight-supporting part in the axial directions are provided in such a way as to each connect to the lid and the weight 15. The weight is arranged at a position separated from both ends of the weight-moving space by the weight-supporting part. COPYRIGHT: (C)2010,JPO&INPIT
