Seat Thermal Manikin
The Seat Thermal Manikin is designed to evaluate the thermal comfort and moisture management performance of seats used in passenger cars, trucks, office chairs, and aircraft seating. Developed based on the SAE J826 HPM-II human body model, it is fully compatible with existing automotive H-point positioning methods.
You can accurately measure heat and moisture exchange for passive seats, and for heated or ventilated seats the system evaluates real energy transfer instead of surface temperature only, while considering realistic sweat rates. This ensures reliable and repeatable assessment of seat thermal performance under realistic conditions.
Application
You can use the Seat Thermal Manikin for the following applications and test objects:
Thermal comfort and moisture management testing of automotive seats
Thermal performance evaluation of truck seats
Long-term comfort and heat dissipation testing of office chairs
Thermal comfort and cooling/ventilation performance assessment of aircraft seats
Performance evaluation of heated seats
Thermal conductivity verification of seat materials and cushions
Automotive seat design validation and ergonomics research
Passenger thermal comfort optimization and HVAC system evaluation
