NVH Engineer_NVH与气动声学工程师

Job objective: Ensure that our vehicles fulfill the Mercedes-Benz standards regarding overall vehicle NVH and sound isolation performance for the Chinese customer. Task description: Derive and implement China-specific

based on own experience and in cooperation with other RD departments • Align and define NVH, sound & aero-acoustic performance targets and develop respective measures together within RD China and the global RD network • Communicate and drive the implementation of the China-specific NVH, sound & aero-acoustic performance in vehicle projects (via Project groups, Commodity groups, Function integration groups). Provide input to functional and module strategies (China Requirement Working Groups, collaboration within global RD network). • Prepare and align NVH, sound & aero-acoustic release documentation Development and adjustment of NVH, sound & aero-acoustic function features to China-specific conditions and requirements • Develop, adjust and validate NVH, sound & aero-acoustic testing procedures to meet major use cases in China in order to evaluate and release the NVH, sound & aero-acoustic performance. • Identify most harming and customer-related parameters based on field research, customer observation and feedback. Plan and conduct NVH, sound & aero-acoustic testing in China • Plan and prepare the required vehicles, parts and resources. • Conduct NVH, sound & aero-acoustic tests according to Mercedes-Benz standards and customer satisfaction. • Coordinate tests on test benches and test facilities of GRC and 3rd parties. • Organize evaluation drives and management drives. • Create test reports and regularly present testing progress in relevant committees. Issue finding, tracking and documentation • Proper documentation of any issue findings in systems accordingly. • Reproduce issues and support further analysis. • Report the updated failure solving status at issue tracking platforms. Education • University degree in acoustic/aero-acoustic engineering or mechanical/automotive engineering or sound/audio design or similar engineering qualification Experience • Working experience at OEMs or suppliers for NVH, sound and aero-acoustic testing and development (including early development phases) preferred. • Familiarity with the China automotive supplier landscape and ecosystem. • Understanding of the market-specific preferences in terms of sound & vibration comfort. • Familiarity with sound isolation component development coordination. • Familiarity with vehicle development process is an advantage (development phases, decision landscape). • Familiarity with wind tunnel testing (aeroacoustics & aerodynamics) and/or sound design is helpful. • Longer stay in Germany or abroad (business or education) is helpful. Specific Knowledge • Solid knowledge of NVH, pass-by-noise, sound and aero-acoustic concepts. • Profound knowledge in designing sound isolation concepts and developing sound isolation packages. • Familiarity with NVH material characteristics, component interactions, and functions. • Experience with NVH & wind tunnel measurement & analysis tools. • Sensitivity for issue detection, root cause analysis and system performance evaluation. • Capability to evaluate test vehicles regarding NVH, sound and aero-acoustic behaviour (both in an objective and a subjective manner) under all conditions. • Collect requirements and turn these requirements into specific concepts and target sound descriptions to ensure the market-specific Mercedes-Benz sound character. Drive the realization of these specifications. • Support the technical and creative sound isolation process of market-specific requirements by initiating market-specific adaptations of the Mercedes-Benz user journey. • Experience with acoustic measurement techniques (e.g., sound intensity, sound pressure level, reciprocal measurements, beam forming, …). • Proficiency in using data acquisition systems and analysis software (e.g., LMS Test.Lab, Head Acoustics). • Ability to conduct vehicle-level NVH testing and analyze test data. • Understanding the material release and manufacturing processes relevant to sound isolation components. • Experience with specific vehicle platforms or systems (e.g., ICE, PHEV, REEV, BEV, powertrain NVH). • Knowledge of advanced sound isolation techniques (e.g., active noise control, metamaterials) and sound cancellation techniques: RNC (Road Noise Cancellation), EoC (Engine order Cancellation). • Develop and implement innovative sound isolation concepts for future vehicle platforms to meet stringent NVH targets. • Collaborate with CAE simulation engineers (SEA, …) to design and optimize the acoustic performance of vehicle components and systems. • Perform vehicle-level NVH testing and analyze data to identify and resolve noise issues. • Collaborate with cross-functional teams to integrate sound isolation solutions into vehicle designs. • Prepare the decision board meetings in interaction with module group speakers and component designers • Using PDM systems to document the geometry changes, processes • Check the sound isolation performance of new materials (innovation, new supplier, …) Other Knowledge • Teamwork spirit with excellent communication, interpersonal and presentation skills. • Initiative and ability to work independently and self-responsibly. • Strong planning and organizational skills. • Proficiency in MS Office tools like PowerPoint, Excel, and Word. • Willingness to travel inside China and foreign countries. • Fluent English and Chinese (oral, writing, listening and reading) is mandatory. • German language knowledge is an advantage. • Good driving skills.
