This paper will explore the performance of two polyurethane foam formulations, one that is designed to be high resilient and one that is designed to be low resilient. The two formulations are placed into a full foam seat suspension. Data is generated with each formulation by a forced vibration test with a tekken mass, both at one point in time and over several hours to simulate in vehicle performance. The Seat Effectiveness Amplitude Transmissibility (SEAT) is read over a one-hour course that includes paved and rough roads, which is repeated three times for a total of three hours of data. This data is then compared to the foam data. The data shows that the low resilient foam will have some improvement in the paved roads but will have a vast improvement in the area of the rough roads. Data will be done by road to show the fatigue level occupant, road type, hour of the ride and drive and the foam type.

Thermophysical properties of materials used in the design of automotive interiors are needed for computer simulation of climate conditions inside the vehicle. These properties are required for assessment of the vehicle occupants' thermal sensation as they come in contact with the vehicle interior components, such as steering wheels, arm rests, instruments panel and seats. This paper presents the results of an investigation into the thermophysical properties of materials which are required for solving the non-linear Fourier equations with any boundary conditions and taking into account materials' specific heat, volume density, thermal conductivity, and thermal optical properties (spectral and total emissivity and absorptivity). The model and results of the computer simulation will be published in a separate paper.
