    Sammanfattning : A hydraulic damper plays an important role in tuning the handling and comfort characteristicsof a vehicle. Tuning and selecting a damper based on subjective evaluation, by considering theopinions of various users, would be an inefficient method since the comfort requirements of usersvary a lot. LÄS MER

    Sammanfattning : Vinkelväxlar och slutväxlar spelar en viktig roll för kraftöverföringen mellan motor och hjuli fyrhjulsdrivna bilar. Med en ökande konkurrens finns en efterfrågan för att ständigt förbättraeffektivitet, ljudgenereringegenskaper och hållfasthet. För att uppnå detta krävs en bättreförståelse av systemets dynamiska egenskaper. LÄS MER
