Ride comfort of patient transport robot chassis

International Journal of Modeling, Simulation, and Scientific Computing, 2023
The ride comfort is a significant property of patient transport robots, which is directly related to the performance of rescue instruments and the cause of secondary damage. Previous studies overlook the design optimization of patient transport robots to improve ride comfort in hospital environments.

Ridemeter – Calculated Ride Comfort

SAE Technical Paper Series, 2007
<div class="htmlview paragraph">The ridemeter is a development tool that provides a predictive value for subjectively perceived ride quality on the basis of objective measured values. After years of preliminary investigations it was possible to make the link between the subjective driving experience and objective measured data.

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.

Vibration Ride Comfort Criteria

Proceedings of the Human Factors Society Annual Meeting, 1976
This paper presents results obtained from a test program being conducted at Langley Research Center to develop an empirical model for predicting passenger comfort responses to multiaxis vibrations. The specific results contained in this paper are restricted to a description and understanding of human response to complex vertical axis vibrations.

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.

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 ...

Development of noise and vibration ride comfort criteria

The Journal of the Acoustical Society of America, 1979
A laboratory investigation was directed at the development of criteria for the prediction of ride quality in a noise-vibration environment. The stimuli for the study consisted of octave bands of noise centered at 500 and 2000 Hz and vertical floor vibrations composed of either 5 Hz sinusoidal vibration, or random vibrations centered at 5 Hz and with a ...
