Parameters Affecting Truck Ride Comfort

SAE Technical Paper Series, 2014
<div class="section abstract"><div class="htmlview paragraph">The road condition has an important influence on ride quality; however, the road condition cannot be sufficiently controlled. The proper design of truck components is the only way to improve ride quality. This work is an investigation into the ride behaviour of passive and active

Correlation between Ride Comfort Index and Sperling's Index for Evaluation Ride Comfort in Railway Vehicles

Applied Mechanics and Materials, 2018
Ride comfort is a reference point in evaluating the dynamic performance in railway vehicles. There are more methods to assess the ride comfort, depending on the traffic details and the specific needs of a railway administration. This paper focuses on the comfort index methods, in accordance with UIC Leaflet 513 R and the standard of railway ...

Ride Comfort Analysis: Practice and Procedures

SAE Technical Paper Series, 1999
<div class="htmlview paragraph">Engineers have traditionally relied on subjective assessment and intution during the development and troubleshooting of a vehicle's ride characteristics. For example, while terms such as ‘soft’ or ‘hard’ can convey a qualitative description of an automobile suspension, they are of little use to design engineer ...

Ride comfort for tractor operators

Journal of Agricultural Engineering Research, 1966
A survey of the undulation severity of agricultural surfaces is reported and a design for easily adjustable simulated surfaces proposed. These surfaces, although initially prepared for the measurement of ride vibration, may be used for performance investigations on other agricultural machinery.

Possible Improvements in Ride Comfort

Vehicle System Dynamics, 1973
SUMMARY The random vertical vibration of two linear models of a sprung mass with a passenger on seat is numerically solved. The input signal has a power spectrum of a real road. The acceleration of the passenger is frequency-weighted according to two various criteria.

Vehicle Ride Quality and Passenger Comfort

Proceedings of the Human Factors Society Annual Meeting, 1978
The state of the art in ride quality assessment is reviewed. A portable environmental measuring system (PEMS II) has been developed to simultaneously record variation in motion (in all six degrees of freedom), temperature and pressure for various segments of a ride.

On Measuring Automobile Seat Ride Comfort

SAE Technical Paper Series, 1982
<div class="htmlview paragraph">A ride number to measure the “ride comfort” of an automobile seat has been developed that could be used to numerically rank nearly all seats. In this research, ride comfort is regarded as the characteristic of the seat that isolates an occupant from annoying road vibrations. The results were obtained from a program
