Do you have these issues?

Vehicle ride comfort is influenced by multiple complex factors such as engine, powertrain, suspension, and tires. This seminar organizes practical methods for ride comfort design, evaluation, and improvement, and connects them to real-world applications.

・ Overall picture of vehicle ride comfort and dominant vibration factors
・ Understanding vibration sources and frequency characteristics
・ Basics of ride comfort evaluation and practical usage
・ Approaches for vibration reduction and comfort improvement at the design stage
・ Improvement procedures and verification through practical case studies
