How do you ensure that you meet NVH objectives in your simulations?

To ensure that I meet NVH objectives in my simulations, I start by thoroughly understanding the NVH requirements and targets set by the design and engineering teams. I then develop and validate computational acoustic models of the vehicle components and assemblies using the relevant software tools. I perform simulations under various operating conditions to predict the vehicle's acoustic behavior. Once the simulations are complete, I analyze the results and make recommendations for design changes to meet the NVH objectives. I also collaborate with cross-functional teams to integrate acoustic design principles into the product development process. Lastly, I stay updated with industry trends and advancements in acoustic simulation technology.

To ensure that I meet NVH objectives in my simulations, I start by thoroughly understanding the NVH requirements and targets set by the design and engineering teams. For example, in my previous role at XYZ Company, I collaborated closely with the design team to define clear NVH targets for a new vehicle model. I then developed detailed computational acoustic models using software tools such as LMS Virtual.Lab and ANSYS. I performed simulations under various driving conditions to predict the vehicle's acoustic behavior. In one project, I focused on optimizing the engine compartment insulation to meet specific noise reduction goals. I analyzed the simulation results, comparing them to the targets, and identified areas for improvement. I suggested design changes, such as adding additional insulation materials or modifying component shapes, to achieve the desired NVH objectives. I effectively communicated my findings and recommendations to the engineering team, providing them with clear insights to guide the design modifications. By implementing these changes, we successfully met the NVH targets and significantly improved the acoustic comfort of the vehicle.

To ensure that I meet NVH objectives in my simulations, I follow a systematic approach that involves thorough understanding of the NVH requirements and targets, developing accurate computational acoustic models, and performing detailed simulations. For instance, in my previous role at XYZ Company, I was responsible for simulating the acoustic behavior of a vehicle's exhaust system. I worked closely with the design team to define the NVH targets, considering factors like overall sound quality, sound levels, and frequency distribution. I developed a comprehensive acoustic model using LMS Virtual.Lab and COMSOL, incorporating all relevant components and boundary conditions. The model was validated by comparing the simulation results with experimental measurements. I optimized the exhaust system design by analyzing various design parameters, such as pipe diameter, muffler configuration, and sound absorption materials. Through iterative simulations and sensitivity analyses, I achieved the desired NVH objectives, significantly reducing the exhaust noise and ensuring a pleasant driving experience. I documented the simulation process and results in a detailed report, which was shared with the design and engineering teams. In addition, I actively participate in industry conferences and webinars to stay updated with the latest advancements in acoustic simulation technology and techniques.
