WebNVH Engineering for Hybrid and Electric Vehicles Siemens Software Address NVH Engineering issues of Hybrid and Electric Vehicles 온디맨드 웨비나 48 분 Deliver … Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via … Meer weergeven The sources of noise in a vehicle can be classified as: • Aerodynamic (e.g., wind, cooling fans of HVAC) • Mechanical (e.g., engine, driveline, tire contact patch and road surface, brakes) Meer weergeven Techniques used to help identify NVH include part substitution, modal analysis, rig squeak and rattle tests (complete vehicle or component/system tests), lead cladding, acoustic intensity, transfer path analysis, and partial coherence. Most NVH work is done … Meer weergeven There are three principal means of improving NVH: • Reducing the source strength, as in making a … Meer weergeven NVH can be tonal such as engine noise, or broadband, such as road noise or wind noise, normally. Some resonant systems respond at characteristic frequencies, but in response … Meer weergeven Typical instrumentation used to measure NVH include microphones, accelerometers and force gauges, or load cells. Many NVH facilities will have semi-anechoic chambers, … Meer weergeven NVH needs good representative prototypes of the production vehicle for testing. These are needed early in the design … Meer weergeven • Acoustic camera • Acoustic quieting • Engine balance • Health effects from noise • Noise control Meer weergeven
