Engineering Simulation Solutions for the Automotive and Ground Transportation Industries

Physical comfort when driving is a very important customer criterion. Human comfort is a subjective perception, influenced by a number of physical state variables. Besides standard heating, ventilation and air-conditioning for thermal comfort, a passenger’s sense of well-being can be affected by noise and solar radiation. Furthermore, reliable defogging and defrosting are essential for the safety of the vehicle’s occupants.

Experimental investigation of a cabin interior is very difficult because of low velocites and small temperature variations in a highly complex geometry. Additionally scale models are not well suited to deliver meaningful results for such a case, only real-car tests can offer significant understanding. Especially in early design stages the expenses associated with mock-ups and prototypes are prohibitive.

Hence simulation is the most efficient approach to obtain maximum comfort by optimizing flow and air quality, increasing equipment life, and providing for thermal and acoustics distribution while minimizing pressure and energy loss.
ANSYS, Inc. provides all the tools necessary for such an upfront design, targeted optimization and virtual validation in a unique, integrated environment. Read more on how the ANSYS tools assist in cabin interior and systems design for passengers feeling well.
