Selection of Traverse Unit
When selecting a traverse unit model, it is essential to consider the various forces and factors that impact its performance. The selection process should account for the cumulative effects of the following:
- The weight of the traverse unit itself
- Associated assemblies being traversed
- Frictional load
- Linear speed
- Other relevant parameters
For spooling applications, it is also important to consider the tension in the material being traversed and the distance between the final capstan/support point and the traverse unit. To calculate the side thrust (F) exerted on the traverse unit, use the following equation:
Side Thrust (F) [Kg] = 0.25 × (M × V / T) + Fr + Fz + 0.12 × (M × G) + Fw
Where:
- M = Total weight to be traversed (Kg)
- V = Maximum linear speed (meters per second)
- T = Reversal time (seconds)
- Fr = Friction load (Kg)
- G = Gravitational force (approximately 9.8 m/s²)
- Fz = Additional applicable force (Kg) if any.
- Fw = Additional force specific to the winding tension (Kg
Ensure that all these factors are thoroughly evaluated to select the appropriate traverse unit for your application.
