WebOrder Tracking Analysis. Structural resonances of variable speed rotating machines (engine, gear box, motor) lead to critical NVH durability and performance issues. OROS order analysis and tracking techniques allow to identify sources of such noise and vibration. en. fr de cn. Our catalog. WebOrder Analysis Application Overview. Order analysis is a technique for analyzing noise and vibration signals in rotating or reciprocating machinery such as engines, compressors, …
WebOrders aid in the analysis of noise and vibration signals in rotating machinery. Each component of a system (gears, shafts, pistons, pumps, tires, etc.) contributes to the overall level of noise and vibration of the system. Order analysis helps to identify how an …
WebStudies were recently conducted on NVH of BEV powertrains. The main emphasis was on the reduction of noise induced by the asynchronous or synchronous motor, gear, and inverter, and the improvement of sound quality. For example, Zeng et al.2 demonstrated an efficient analytical strategy comprising order analysis, oper- WebOrder analysis relates measurements to revolutions of a rotating part, improving knowledge about machinery such as aircraft and automotive engines, powertrains, pumps, compressors and electric motors. In rotating and reciprocating machines, varying load conditions and imperfections in the moving parts cause vibrations and associated sounds. The ...
