WebMeasure the diameter of the shaft. 2. Measure the length of the shaft. 3. Fix the given shaft in between two end-fixing blocks with a particular type of end conditions (simply supported or fixed) 4. Start the motors and go to the maximum speed rapidly. WebTecQuipment’s Whirling of Shafts and Critical Speed apparatus (TM1001) shows how shafts vibrate transversely and ‘whirl’ at a certain rotation frequency. This helps engineers understand possible problems with long shafts and allow for them in their designs. The equipment is in two parts and fits on a bench or desktop.

WebPart A: Whirling of shafts without loading 1. Attach a shaft of known diameter and length to the apparatus. 2. Select simply supported configuration by moving out the sliding part of the kinematic coupling and using the free support at the other end. Calculate the theoretical first and second whirling speeds from eq. (1). WebRotating shafts can produce vibration and whirling. The critical speed of the shaft can cause the shaft to fail. Figure 1: Whirling of Shaft due to Unbalance [1] Part 2: Continuous Shaft: A continuous shaft will be analysed in this experiment, it is considered to have an infinite number of functions and natural frequencies. At its critical ...
Webthe whirling of shaft and its motion comes under the category of self-excited motion i.e. self-excited vibration in which the exciting forces and inducing motion are controlled by the motion itself. When the induced frequency matches with natural frequency, resonance will occur at certain speed, this speed is called as „critical speed‟. ...
WebThe demonstration of basic whirling was achieved and the 1st and 2nd mode whirling of shafts of with different diameters was also observed. It was shown through calculations that the relationship between whirl speed and diameter is directly proportional. In conclusion, the experiment was successfully as all the aims of the experiment were achieved how to use a floor buffer machineWebEXPERIMENT NO. 5 – WHIRLING OF SHAFT OBJECTIVE: After completing this experiment student should be able to Understand the concept of critical speed of … how to use a floor sanderWebSep 12, 2024 · ω = Angular velocity of the shaft. As shown in fig (b), the two forces acting on the rotor when it is rotating, are: Centrifugal force acting radially outwards through CG = m ω² (y+e) Force resisting the deflection (or restoring force) = s y For equilibrium, Centrifugal force = Restoring force ∴ m ω² (y+e) = s. y or m.ω².y + m.ω².e = s.y how to use a floor scrubber machineWebWhirling OF Shafts Experiment. 10.
