An increasing number of off-highway manufacturers consider optimizing driver comfort as a priority. Reduced interior noise levels and minimal vibrations afford comfortable driving and a pleasant working environment, even in extreme operating conditions. Moreover, regulations and industry norms dictate ever-stringent levels of noise emission and vibration comfort.
Developing excavators, construction equipment or forklift trucks to meet the required noise and vibration comfort levels represents a complex challenge. The comfort and the noise that the driver or operator will actually experience is the result of complex interactions between multiple subsystems and components that may include hydraulics and chain or gear-drive systems.
LMS offers a unique combination of advanced services and solutions to optimize the NVH performance of designs:
- Qualify and optimize the noise and vibration performance of physical prototypes, using dedicated measurement and analysis systems for lab and in-vehicle testing
- Visualize structural deformations and acoustic fields to gain a better insights in noise and vibration phenomena
- Trace the root cause of noise and vibration problems, through an in-depth analysis of the different sources, transfer paths and vibrating panels
- Assess and optimize the transmission of powertrain induced noise and vibrations throughout the vehicle using virtual simulation models
- Use virtual models to qualify and improve the acoustic performance of intake and exhaust
