..., and a prototype model was fabricated for this scenario. The chassis was uniquely reconfigured in two ways: (1) by adjusting the clearance and (2) by changing the wheel gauge. The reconfiguration of the clearance was necessary to operate the vehicle over a range of heights of bio-energy crops at different growing...

The considered setup is an industrial weaving machine à blanc equipped with a centrifugal pendulum prototype. Below a critical speed, the prototype functions as predicted and significantly improves the machine dynamics...

... with soft prototype and production tooling. The methodology yields a Pareto optimal set that compares the production costs and lead times as a function of the production quantity. The results indicate that the average cost per enclosure assembly is highly sensitive to the production quantity, with average...
