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 کاملDynamic modeling of a part mating problem: threaded fastener insertion
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...
متن کاملLifetime Prediction of Plastic Parts - Case Studies
Lifetime prediction of plastics is a very difficult proposition, but one that is becoming increasingly important as plastics are used in more demanding and critical applications. The lifetime of a plastic part is influenced greatly by many factors including the type of plastic, stress level, temperature, type of loading, and environmental conditions. All these factors make absolute lifetime pre...
متن کاملInvestigation of friction between plastic parts
The goal for this master thesis is to improve and map the main factors behind friction and wear for a commercial product used by Kongsberg automotive. Components in a gear shifter are investigated and the target is to achieve high tribological quality of the force transmission. Finding a solution for low friction and wear which is independent of lubrication is the main issue for all involved co...
