JOURNAL FREE ACCESSExperiments usillg the baIhstic pendulum have been carried out for evaluating ability to propagate explosion and explosive power of some organic peroxides．Among the tested 14 peroxides，five were shown to propagate explosion（violent deflagration）. These results agree fairly well with those obtained using the Mk m ballistic mortar．High explosive powers were often recorded owing to an induced ex－ plosion by the strong booster、Therefore，an evaluation method was devised for obtaining the explosion power due to the self－sustaining explosion.

JOURNAL FREE ACCESSTest methods for evaluating shock sensitivity， abihty to propagate an explosion and power of explosion of organic peroxides have been developed using the Mk Ⅲ ballistic mortar. The shock sensitivity tests consist of the small gap test for peroxides of high sensitivity and the valiable initiator test for those of medium or low sensitivity． In these test methods，shocks of different strength were given to the sample by variable initiator alnount or card gap depth. Propagation of detonation or violent defiagration was judged from the increasing power of explosion with illcreasing sample mount in the Mk III ballistic mortar test． The power of explosion of the peroxide which propagated an explosion was determined from the slope of the swing length－sample weight line. Test results for 17 substances were listed.

JOURNAL FREE ACCESSThis paper is doncerned with an On-line estimation of vibrational characteristics of mechanical structures by identifying their mathematical models, First, model paramete.rs was estimated from vibrational data using Kalman filter based on the least squares method. Then, both of natural frequency and damping ratio were calculated from model parameters by regarding structures as linear second order systems, From experimental results, it was fotind that vibrational characteristics was estimated accurately. Furtherrnore, dynamics changes could be detected with on-1ine by the use of this method.
