Riveting Hammer Vibration and Nerve Damage
Hand Arm Vibration Syndrome (HAVS) is an occupational disease affecting 50% of riveting hammer operators after 10 years of work. Current international standards (ISO 5349) seeking to protect workers from occupational vibration are not effectively predicting HAVS onset. Scarce research has been done which investigates the long term effects of riveting hammer vibration exposure and nerve regenera...
متن کاملJoining of Cold-Reduced Carbon Steel Sheet and Aluminum Sheet by Impulsive Riveting Method and Punch Riveting Method
The impulsive riveting method is described as the punching and joining of sheet metal carried out using the impulsive energy of a weight accelerated by an air compressor. Parts are held together between the rivet and rivet-holder. A hole is made in the sheets by the high speed collision of rivet and a weight (approximately 100 m/s or more). Another method, punch riveting, joins the sheets by pr...
متن کاملErgonomic Field Assessment of Bucking Bars during Riveting Tasks
Riveting tasks in aircraft manufacturing results in exposure to vibration from both rivet guns and bucking bars. Long term exposure to vibration has been associated with symptoms of vibration white finger and musculoskeletal disorders. Four different bucking bars of the same shape but different material and mass characteristics (90% tungsten, >90% tungsten, cold rolled and stainless steel) were...
متن کاملAn investigation into the acute vascular effects of riveting.
Measurements were made on 46 pairs of riveters and matched control subjects before and after a morning's work. Before starting work, the mean resting finger systolic pressure was 112 (SEM 3.3) mm Hg in the riveters, similar to 117 (1.7) in the control subjects. After cooling the middle phalanx to 10 degrees C for five minutes, 16 riveters but only one control subject exhibited digital vasospasm...
متن کاملEfect of Variations of Riveting Process on the Quality of Riveted Joints
This thesis presents a study of the effect of controllable riveting parameters, mainly squeeze force, rivet length, rivet diameter tolerance, hole countersunk depth and hole diameter tolerance, on the quality of formed rivet. The quality of a formed rivet is determined by the geometry of its head formation and the extent to which the hole is filled. The study determines maximum allowable tolera...
