A new equipment for measuring friction force between ring and traveler is introduced. The equipment changes the friction force into strain of the cantilever on which four strain gauges are stuck. The strain of cantilever results in varying resistance value of strain gauge and the variation of the resistance value influence output voltage which is amplified and shown on the dynamic strain indicator. Based on the data shown on the dynamic strain indicator which is demarcated, the friction force can be calculated out. From experimental result, it can be found that the precision of experimental result is about 0.5g |
