Title: Gearbox Load and Life Simulation Software
Agency / Branch: DOD / NAVY
Contract: N68335-10-C-0400
Award Amount: $1,041,095.00


The overall objective of this proposed effort is to build a gearbox system life simulator that is capable of estimating loads and life of components (e.g., recommended removal time) based on the users"drive system design parameters (dimension, weight, diameter, number of teeth, material, loads, gear ratios, etc). This VEXTEC SBIR Phase II will take advantage of several previous DoD technology development investments. Under Phase I feasibility demonstration, the existing high fidelity modeling capability was enhanced with the addition of gearbox mission variability to a representative helicopter transmission system, resulting in a demonstrator tool. Over the Phase II period, this methodology will be further enhanced with an expanded helicopter transmission system and a robust complex mission capability to study transmission system durability under fielded conditions.
