§5 Ride Quality and Its Evaluation Criterion Introduction Dynamic load coefficient Amplitude of acceleration Ride quality of passenger car §5 Ride Quality and Its Evaluation Criterion Introduction Ride quality is usually interpreted as the capability of the vehicle suspension to maintain the motion within the range of human comfort and/or within the range necessary to ensure that there is no lading damage. The ride quality of a vehicle depends on displacement, accelerations, rate of change of acceleration, and other factors such as noise, dust, humidity, and temperature. Generally, two approaches are used to evaluate the ride quality of a vehicle: the fatigue time and the ride index method. §5 Ride Quality and Its Evaluation Criterion Introduction as to the passenger vehicle: §5 Ride Quality and Its Evaluation Criterion Dynamic load coefficient §5 Ride Quality and Its Evaluation Criterion Dynamic load coefficient §5 Ride Quality and Its Evaluation Criterion Dynamic load coefficient §5 Ride Quality and Its Evaluation Criterion Acceleration amplitude of carbody §5 Ride Quality and Its Evaluation Criterion Acceleration amplitude of carbody §5 Ride Quality and Its Evaluation Criterion Ride quality of passenger car §5 Ride Quality and Its Evaluation Criterion Ride quality (Sperling) §5 Ride Quality and Its Evaluation Criterion Ride quality (Sperling) §5 Ride Quality and Its Evaluation Criterion Ride quality (Sperling) §5 Ride Quality and Its Evaluation Criterion Ride quality (Sperling) §5 Ride Quality and Its Evaluation Criterion Ride quality (Sperling) §5 Ride Quality and Its Evaluation Criterion Ride quality (Sperling) §5 Ride Quality and Its Evaluation Criterion Ride quality (Sperling) §5 Ride Quality and Its Evaluation Criterion Ride quality (UIC513) §5 Ride Quality and Its Evaluation Criterion Sw160 Wu han-Shen zen, Lateral, end of carbody §5 Ride Quality and Its Evaluation C
