Subject: Life Cycle Environmental Profile
Message:
Help! I am trying to create a Life Cycle Environmental Profile (LCEP) to help guide a series of qualification tests. The LCEP defines all of the environmental stresses that the product is likely to encounter from manufacturing, shipping, storage, installation, and use. I have been able to get reasonably good data on all of these environments except for installation. The product is a tower mounted reciever front end module, approximately 100 lbs. My problem is that the installation environment can vary quite a bit (from wall mounted to several hundred feet up whatever style of tower imaginable). I anticipate mechanical shock as the unit is hauled up the tower will be the main concern. Does anyone out there have any experience that could help? If I can not find existing data I plan to attempt a rough "worst case" estimate. Does this seem reasonable? Thanks for any help you can give me (I'm fairly new to reliability engineering) Dave
