METHOD OF OVERLOAD PULSE FORMATION AT IMPACT TESTS |
摘要 |
FIELD: mechanical engineering. SUBSTANCE: platform with object under test positioned loosely on it is accelerated till it collides with braking device, and object is braked by second braking device. The latter is positioned between object and platform. Method enable increase in amplitude and rate of pulse rise due to installation of object relative to second braking device with clearance to be selected from relation <EMI ID=0.378 HE=9 WI=60 TI=CHI>, where delta is clearance; v<SB>0</SB> is platform acceleration speed; g is free fall acceleration; n<SB>1</SB> is overload on platform; n<SB>2</SB> is overload of object under test; K is empirical coefficient which depends on correlation of masses of object under test and platform and on overload pulse forms on object under test and platform. EFFECT: enhanced formation of overload pulse. 1 dwga
