Diameter of Cylinder with Maximum Holding Force under Rapid Loading Conditions

The aim of this study is to investigate the relation between diameter of cylindrical object and holding force under the condition of rapid increment of load. The holding force was in a range from 100 to 300 N at the diameter of cylinder between 15 and 60 mm. The maximum force was obtained from the c...

Summary:The aim of this study is to investigate the relation between diameter of cylindrical object and holding force under the condition of rapid increment of load. The holding force was in a range from 100 to 300 N at the diameter of cylinder between 15 and 60 mm. The maximum force was obtained from the cylinder with a diameter of 20 and 25 mm. In the comparison with the results from the static holding condition, the present results showed that the larger force was appeared at the thinner cylinder. When electromyogram was recorded from the grasping muscles during constant loading, the integrated value of the electromyogram showed the minimum value at the cylinder diameter at which the maximum force was obtained. Experimental results show the existence of the optimum diameter to transmit the muscle force to the cylindrical object with good efficiency.
