The surgical skills required to successfully maintain hemostasis, the control of operative blood, requires considerable deliberate practice. Hemostasis requires the deft orchestration of bi-dexterous tool manipulation. We present our approach to computationally emulate both irrigation and bleeding associated with neurotologic surgical technique. The overall objective is to provide a visually plausible, three dimensional, real-time simulation of bleeding and irrigation in a virtual otologic simulator system. The results present a unique simulation environment for deliberate study and practice.

This paper presents a reduction strategy for a multibody model of a 7.5 MW gearbox located at Clemson University’s Wind Turbine Drivetrain Testing Facility in North Charleston, SC. A model reduction is needed because of a high frequency dynamic associated with the input shaft of the gearbox which prevents the model from being executed in real-time. This particular gearbox has an atypical input stage configuration whereby the load path is split into two parallel shafts before being recombined at the sun shaft. The strategy includes removing model elements associated with high frequency vibration, merging model elements, and locating model elements where needed. The presented strategy successfully removes the problematic eigenvalues, maintains basic dynamic character, and results in a multibody gearbox model suitable for real-time simulation.
