Table 3 shows subjective evaluation scores of noise and shake in an electric vehicle with different mount stiffness schemes. Among these three schemes, scheme A is to increase the left and right mount stiffness from 260 N/mm to 360 N/mm, and scheme B is to increase the rear mount stiffness from 230 N/mm to 290 N/mm in addition to scheme A. changes to resolve the NVH issue were validated at the full vehicle level. ANALYTICAL AND EXPERIMENTAL WORK POWERTRAIN BENDING INDUCED VEHICLE HIGH SPEED NVH CONCERNS A pre-production vehicle with a four-wheel-drive (4x4) powertrain system experienced noticeable interior noise and seat track vibration problems at speed ranges of 80 ~ 90 mph The study's motivation was the assessment of the NVH behavior of a motorbike engine driveline, during its working condition, in first gear. More precisely, its behavior was considered in transient conditions powertrain system, which was used to study the effects of design variants both at a component (driven fifth gear, driving shaft) and Basics of the Powertrain NVH: Part 1. The powertrain of an automobile is the combination of the main moving parts that include the engine and transmission. This blog will hence deal with understanding the concept of powertrain NVH ( Noise, Vibration, Hardness) and how it affects the design configuration of the power train of the vehicle. root cause in NVH issues can originate from a range of sources, and as such it is no surprise that difficulties can be encountered by limiting the search for a solution in gear micro geometry alone. This paper will discuss the way in which NVH issues can be caused, as well as the way in which they can be analysed and solved. Figure 1 shows that the NVH development process of powertrain mounts typically goes through several phases. At first phase the performance targets are defined. In the second phase the conceptual layout of the powertrain mounting system is realised. The output of this concept design is a list of characteristics for mounts, which are then challenge during the development of such a powertrain is that no degradation on customer demands regarding the key criteria, among others driveability and NVH, is allowed. This paper will show the powertrain components that are affected most by these NVH attributes; this concerns mainly the engine and the power conversion system. The Noise Vibration Harshness (NVH) In close cooperation with the international OEMs, BOGE Rubber & Plastics develops and manufactures mounts for the vehicle powertrain. Mounts are rubber-metal or plastic components in the form of supporting connection elements between the powertrain and the vehicle body. They ensure that engine •Engineers can use the same vehicle dynamic model for powertrain and NVH development. •Experience a virtual prototype based on combination of test data, CAE data and test bench data.
