A conveyor drive system to produce translation of the load is shown in Figure. The reducer is
Question:
Sprockets:
Sprocket 1: radius = 0.05 m mass = 0.9 kg
Sprocket 2: radius = 0.15 m mass = 8.9 kg
Chain mass: 10.7 kg
Drive shaft: radius = 0.04 m mass = 2.2 kg
Drive wheels (four of them): radius = 0.2 m mass = 8.9 kg each
Drive chains (two of them): mass = 67 kg each
Load friction torque measured at the drive shaft: 54 N.m
Load mass: 45 kg
a. Derive the equation of motion of the conveyor in terms of the motor velocity ω1, with the motor torque T1 as the input.
b. Suppose the motor torque is constant at 10 N.m. Determine the resulting motor velocity ω1 and load velocity v as functions of time, assuming the system starts from rest.
c. The profile of a desired velocity for the load is shown in Figure, where vo = 1 m/s, t1= t3 = 0.5s, and t2 = 2 s. Use the equation of motion found in part (a) to compute the required motor torque for each part of the profile.
