Title:
DEVICE FOR MEASURING DYNAMIC CHARACTERISTICS OF OBJECTS DURING IMPACT
Document Type and Number:
WIPO Patent Application WO/1982/000715
Kind Code:
A1
Abstract:
A device for measuring dynamic characteristics of objects during impact comprises, connected in series, a sensor (1) of displacement parameters of the object during the impact, a pulse former (2) and a controllable key (3). To the output of the latter are connected through inputs a unit (7) for measuring the impact area, an integrator (8) and two elements AND-NO (9) and (10), the second inputs of which are connected to the output of the integrator (8). The device further comprises three additional controllable keys (4, 5, and 6). The key (4) is connected through one input to the output of the unit (7) for measuring the impact area, through another input - to the output of the element AND-NO (10) and through the output - to the input of a memory register (13). The key (5) is connected through input to the output of the unit (7) for measuring the impact area, through input, through a logic element NO (11), - to the output of the logic element AND-NO (10) and through the output - to the input of a memory register (14). The key (6) is connected through one input to the output of the key (3), through another input - to the output of the key (3) and through the output - to the controllable input of the key (3) and to the input of a trigger (12) connected in its turn through its outputs respectively to the second inputs of the memory registers (13, 14). The memory registers (13, 14) are connected through outputs, through square - low generators (15, 16) respectively and through an adder (17) - to the input of an indicator (18). The device for measuring dynamic characteristics of objects during the impact may be used when manufacturing dampers, shock absorbers and for mastering equally resistant articles when testing their resistance to impact overloads.
