Predicting passenger seat comfort and discomfort on the basis of human, context and seat characteristics: a literature review

This literature review focused on passenger seat comfort and discomfort in a human-product-context interaction. The relationships between anthropometric variables (human level), activities (context level), seat characteristics (product level) and the perception of comfort and discomfort were studied through mediating variables, such as body...

Technical note: Spine loading in automotive seating

For car manufacturers, seat comfort is becoming more important in distinguishing themselves from their competitors. Therefore, many studies on participative seat comfort are carried out. In this paper, an objective assessment approach is reported which evaluates the concept of "optimal load distribution", based on the identification of a close...

Effects of differences in office chair controls, seat and backrest angle design in relation to tasks

In this study the influence of chair characteristics on comfort, discomfort, adjustment time and seat interface pressure is investigated during VDU and non-VDU tasks: The two investigated office chairs, both designed according to European and Dutch standards are different regarding: 1) seat cushioning and shape, 2) backrest angle and 3) controls...

Integrated hydrodynamic analysis of fluid pressure and leak-off pressure distributions to evaluate seal effectiveness

Hydrodynamic methods are used to analyse the present-day fluid overpressure and leak-off pressure distributions in offshore Netherlands in combination with recently completed stratigraphic and structural maps, and knowledge on distribution and characteristics of oil and gas accumulations. This paper presents an overview of the results, including...

A seat sensitivity study on vertical vibrations and seat pressure distributions using numerical models

Investigation of seat pressure distributions at the human-seat contact interface by analyses with a FE Buttocks model

Estimating regional pore pressure distribution using 3D seismic velocities in the Dutch Central North Sea Graben

The application of the empirical Eaton method to calibrated sonic well information and 3D seismic interval velocity data in the southeastern part of the Central North Sea Graben, using the Japsen (Glob. Planet. Change 24 (2000) 189) normal velocitydepth trend, resulted in the identification of an undercompacted and overpressured zone within the...

Development of a FEM pelvis model for analysis of pressure distributions

Higher demands by people on the performance of vehicles and the comfort-related physical complaints by professional drivers have led to an increasing demand for more comfortable cars. Car manufacturers use comfort as an item to distinguish themselves from their competitors. However, the development and introduction of a new, more-comfortable car...

Vibration analysis with MADYMO human models

The importance of comfort for the automotive industry is increasing. Car manufacturers use comfort to distinguish their products from their competitors. However, the development and design of a new car seat or interior is very time consuming and expensive. The introduction of computer models of human and seat could accelerate this process. This...

Velocity-pressure correlation in stagnation and separation regions on surface-mounted prisms

Experiments are presented for a 1:50 scale model of the Wind Engineering Research Field Laboratory (WERFL) experimental building located on the Texas Tech University campus in Lubbock, Texas. The model was immersed in three different boundary layers generated in the Clemson University wind tunnel. These flows closely simulated the lowest 50 m of...
