Delivering on the Promises of Digital Twins and Big DataAs a community, we gear engineers collaborate and share ideas to progress our collective capability. Technology progresses based on our efforts, and we have seen solid advances in the performance of our products as they become quieter, cheaper, more efficient, and more power dense. The pages of this magazine (past and present editions) are filled with examples where talented engineers have dug deeper into a subject using a more precise approach to a particular area concerning gear performance. The implied belief is always that greater precision (complexity) in the calculations brings greater accuracy (alignment with reality).Cross-Correlation of Design Variables for Epicyclic SystemsThe automotive industry pays great attention to the concept of power density and friction losses concerning mechanical transmission systems. Moreover, installation benefits and weight reduction are achieving higher density power. Another important study is about mechanical efficiency: their reduction allows to minimize the heat exchange; the power dissipation problem—produced by friction—must be addressed. Therefore, the gear designer is obligated to incorporate additional cooling systems, or with higher capacity, to address this problem. This paper shows a methodology to extensively evaluate different designs of epicyclic gear systems. | ||
