Modelling Workshop Mechanics 2: Problem Document Transcript

  • 1. P-W-M-2: The Uno single wheel bike The Bike Courtesy of http://duasrodas.blog.br/2009/03/10/uno-a-moto-de-apenas-uma-roda/ Designer: Ben Gulak The UnoCycle® is a single-wheel, single-rider vehicle.
  • 2. Question: Build a model to describe the vertical movement of the bike when it passes a road. Basedies the step, what will happen if he passes a bumpy road as 0.05$ heaviside 0 C0.003$ cos 50$ t C0.001$cos 100$t . Try to change the "frequency" of the bumpy road and observe the behavior of the system 1st case: We choose 1. the mass of the bike wheel, is mw=3kg, the bike is mb= 17kg the mass of the rider is mr=60kg; 2. the bike is rigid except the tire, the spring constant of the tire is Kt=15000n/m, the damping coefficient of the tire is Ct=20; 3. there is a step in the road which is 5cm high; 4. to neglect the air friction. 2nd case: We choose 1. the mass of the bike wheel, is mw=3kg, the bike is mb= 17kg the mass of the rider is mr=60kg; 2. There is suspension system in the vertical direction between the wheel and the bike, the sping constant of the suspension system is Ks=10000n/m, the damping coefficient is Cs=200 3. the spring constant of the tire is Kt=15000n/m; the damping coefficient of the tire is Ct = 20; 4. there is a step in the road which is 5cm high, besides, the road is bumpy can be described as a function of time as y(t)=0.003$ cos 50$ t C0.001$cos 100$t in the vertical direction; 5. to neglect the air friction.
