W-2. Designing the winch drum and drive train for low cost
Design the winch drum and drive train for the following system specification:
- linear speed at which the cable is to be reeled on the drum 2 m/s
- force/tension on the cable 10 kN
- overloads - 20 %
- grid voltage 690 V
- capacity of the winch - 1 m3
Design drum by varying:
- empty drum diameter (D1)
- full drum diameter (D2)
- drum length (L)
Optimize for lowest drive train cost. Assume cost of the drum negligible.
