Do you want the relay to operate on 12 VDC or do you want it to open some circuit when some supply falls below 11.9999999999999999999999 volts?

Add a voltage comparator and electronic switch to a standard relay.

i need its complete calculation and design.

Without more information we cannot.

This brings to mind the cut-out relay between a motor car [commutator] dynamo generator and battery.

Did I guess correctly?

Try looking for 36V Strobe Circuit in CR4 search window. Post #6 of that may be what you want, but there are several other suggestions.The direction flasher in my car looks like an "NE555 type" integrated circuit driving a relay.
