The appratus, method, and result of experimental investigation of load-carrying capacity of rolled magnetic tapes subjected to impact and thermal effects are described. Analysis of the basic regularities of loss of load-carrying capacity of the rolls (lamination of turns) has facilitated determination of the safe level of impact accelerations and thermal effects which do not cause damage of rolls under multiple impacts (10...10 cycles). It is established that breakdown in compactness of rolled magnetic tapes under multiple impacts occurs due to reduction in interturn pressures (up to 30 ... 50% of the original level). It is noted that, with increase in environmental temperature, there is sharp reduction in load-carrying capacity of rolls under the action of impact loads. [ABSTRACT FROM AUTHOR] |
