  Hi,
  My repeat counts are 1500 for all directions which are X-Y-Z. After I found the life as second, how many should I divide by 1500 or 4500 or 3600 to calculate as hours?

  If you request the life in seconds for the entire duty cycle, that value represents the allowable number of seconds of exposure for the entire duty cycle. Your duty cycle contains 1500 repeats of event 1, 1500 repeats for event 2, and 1500 repeats of event 3. So, the reported life is the allowable number of seconds of exposure for all 4500 repeats. To convert the calculated life to hours, divide the life in seconds by 3600.

    I really appreciate it. Thanks to you I developed myself.
    In addition, sometimes the life can be seen as 1732 repeats and damage is 124, so must I use EN curve instead of SN curve?
