Dynamic
Similation Optimized Contact II (DSOC II)
New design technology represents a leap in tire development
During running, a tire is in a constant state of change -bending, expanding and
flexing -in response to forces received from the road. This flexibility and resilience
is also what makes it possible for a car to transmit energy to the road, ensuring
accurate acceleration, turning and braking. In order to improve the performance
of its tires, Toyo has turned to the imaginary world of super-computer analysis
technology.
With conventional experimental techniques, it is essentially impossible to understand
the changes that a tire undergoes during running at the surface where it touches
the road. Toyo has already won much recognition for its highly regarded Dynamic
Simulation Optimized Contact Theory (DSOC- T) that was developed to include these
changes in the tire design process.
Toyo has now developed a new, more advanced design theory, Dynamic Simulation
Optimized Contact II (DSOC II). New simulation techniques employing a full-pattern
model are used to analyze tire behavior at the road contact surface even at the
level of detailed tread pattern, making it possible to predict with high precision
tire changes during running. This modeling capability has meant a great leap
in the sophistication of Toyo's design process, and enabled optimized overall
tire design combining improvements in pattern, form, internal structure and materials.
DSOC II is composed of two analysis software packages, STACS and CASPAN. STACS
is 3-dimensional non-linear structural analysis software that enables the study
of wear phenomena and forces acting at the road contact surface, with a full
pattern model. CASPAN is noise analysis software for predicting noise produced
by the tread pattern during running.
DSOC II is a powerful tool for more sophisticated design of such key tire performance
features as wear resistance, running stability, durability, fuel economy and
rim fit. Toyo is confident that DSOC II will enable the development of new products
which respond to users' needs like never before.
