Dynamic modeling of a part mating problem: threaded fastener insertion
نویسندگان
چکیده
A dynamic simulation of threaded insertion is developed based on Euler's equations, impulsive forces, and a geometric description for threaded parts. Points of contact between the threaded parts are determined and tracked during the simulation. Reaction forces are computed based on the contact locations and the velocity constraints given by the kinematic description. The simulation will be used to investigate the behavior of the bolt during insertion into the nut under grasp stiiness and damper control.

Compliant Control of Threaded Fastener Insertion
Controlled compliance and accommodation matrix techniques are considered for robust insertion of threaded fasteners. Errors in translational positioning are shown to be easily corrected. Errors in the angle of tilt between the threaded parts are shown to be much more diicult to correct and constrain the region of convergence for simple linear techniques.
متن کاملForces associated with pneumatic power screwdriver operation: statics and dynamics.
The statics and dynamics of pneumatic power screwdriver operation were investigated in the context of predicting forces acting against the human operator. A static force model is described in the paper, based on tool geometry, mass, orientation in space, feed force, torque build up, and stall torque. Three common power hand tool shapes are considered, including pistol grip, right angle, and in-...
متن کاملA Dynamic Mechanical Model for Hand Force in Right Angle Nutrunner Operation
A deterministic mechanical model based on physical tool parameters was used for estimating static and dynamic hand forces from kinematic measurements. We investigated the effects of target torque (25, 40, and 55 Nm) and threaded fastener joint hardness (35-, 150-, 300-, 500-, and 900-ms torque buildup time) on hand force. Estimated hand force was affected by target torque and joint hardness. Pe...
متن کاملA Two Parameter Fracture Mechanics Approach to Analyze Threaded Fasteners of A High Strength Steel
This paper presents a numerical investigation using the two-parameter fracture mechanics approach for studying threaded fastener geometries. It was found that the constraint arising from the presence of a surface crack in a threaded fastener does influence the stress in the forward sector. Consequently, the actual stress field shows a deviation from the theoretical HRR solution. Implementation ...
