Abstract
The study focuses on the noise generation due to wear in worm gear systems used in Electric Power Steering (EPS) mechanisms. EPS systems, widely adopted for their precision and environmental benefits, often employ worm gear transmissions that are susceptible to wear under fatigue loads. This wear contributes to undesirable noises which affect vehicle comfort and safety. The research investigates noise related to worm gear wear through kinematic analysis and bench testing, simulating real vehicle conditions. The methods consider acquiring kinematic behavior of EPS at the vehicle level to introduce test conditions for the explained scenario into the bench level. While the durability test is being performed, at certain steps, noise test bench simulation utilizing is beneficial due to its possible correlation with the vehicle level, therefore such testing is significantly more efficient (faster, avoids main issue over the design phase period – vehicle availability). The study finds that worm gear noise increases non-linearly with wear, with significant noise escalation occurring at 80% to 90% of the vehicle's defined life. The findings highlight the need for robust NVH (Noise, Vibration, Harshness) performance assessments during the EPS design process, emphasizing customer satisfaction and product reliability. This work underscores the importance of experimental evaluation which support and lead to mitigating noise issues in EPS systems.
