However, it is also a common expansion to express annoyance at something, i.e., Do you know what grinds my gears? X, Y, and Z but not necessarily in that order.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<h2 class=\"wp-block-heading\"><strong>Gggrrrrr!!!<\/strong><\/h2>\n\n\n\n<p>Extremely repetitive processes that are easy to make mistakes during, grind my gears. This is especially true when I know a computer could do it in a flash if only I had the code to do it. As a very infrequent coder there is always the urge to code something, but cleaning up my buggy code will likely take longer to fix than it would have taken to do the original task. So, it is only worthwhile if the code is likely to get used somewhat regularly.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<figure class=\"wp-block-video\"><video controls src=\"https:\/\/videos.mentor-cdn.com\/mgc\/videos\/5400\/9f1089b6-7404-4b71-ab37-6a7d2e538f35-en-US-video.mp4\"><\/video><\/figure>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Consider macro and micro geometries<\/strong><\/h2>\n\n\n\n<p>Therefore, I sympathize with gear specialists who may face both the literal and metaphorical incarnation of this expression. When developing a transmission, you may need to optimize it for NVH, durability, efficiency, or a combination. To do this, you need to consider both the macro and micro geometry of the gear pairs. In a case with just two gear pairs, there will be approximately 40 design variables, and several objective functions for the microgeometry, plus several more objectives with multiple constraints for the macrogeometry.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Code that works<\/strong><\/h2>\n\n\n\n<p>As I just described, setting up a test that looked at two gear sets in mesh could take an experienced engineer weeks. However, you could reduce this to days if you were fortunate enough to be in a company that already has and does a good job of maintaining a script that evaluates gear key performance indicators. Much time is spent by gear specialists on repetitive workflows or maintaining code at much expense to their companies.

Design Optimization tool builds on the existing capabilities of the Simcenter Motion 3D Transmission builder with new capabilities that allow you to optimize your design using the power of Simcenter HEEDS and evaluate non-multibody key performance indicators such as efficiency and durability. You can now develop designs you may never have conceived in a time frame you would have never thought possible in a general-purpose simulation tool.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">White paper<\/h2>\n\n\n\n<p>Read our latest white paper to learn more about the capabilities Simcenter 3D has for the development of gears. <\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/resources.sw.siemens.com\/en-US\/white-paper-gearbox-multibody-simulation\/?bc=eyJwYWdlIjoiaXZjNzdnaFlvT0MyQlJza1ZEOEFSIiwic2l0ZSI6InBsbSIsImxvY2FsZSI6ImVuLVVTIn0=&amp;lnc=eyJzbHVnIjoibG9jYWwtbmF2aWdhdGlvbi1wbG0tc2ltY2VudGVyIiwidGl0bGUiOnsidGl0bGUiOiJTaW1jZW50ZXIiLCJjYXRlZ29yeSI6IlNhbWUgU2l0ZSIsInVybCI6Imh0dHBzOi8vcGxtLnN3LnNpZW1lbnMuY29tL2VuLVVTL3NpbWNlbnRlci8iLCJjb250ZXh0IjpmYWxzZX0sImxvY2FsZSI6ImVuLVVTIn0=\" target=\"_blank\" rel=\"noreferrer noopener\">Learn more<\/a><\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Simcenter 3D blogs<\/h2>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>This new tool was released as part of the Simcenter Mechanical Simulation Solutions set of 2412 release.
