In this report, I will solve for the angular velocity between two universally jointed shafts. The solution will be derived from analytical and numeral methods. The scope of this project is to simulate a complex problem into CREO mechanisms and compare results with analytical results.
Universal joints consist of two yoke members for input and output. In addition, a connecting cross is required to help transfer power between both shafts. When the input yoke and output yokes are in straight motion, the angular velocity is the same for both shafts. [Figure 1] However, when there is an angle offset between the yokes, in theory, angular velocity output would be different than the input. [Figure 2] In 1.2 seconds, the fork reached minimum angular velocity at horizontal position. By 2.4 sec, the fork reached back to original vertical position at maximum angular velocity of -82.8 deg/sec. |
