Claim One:
1. Apparatus for simulating the heat transfer in a tire to determine the state of cure of the tire comprising means for generating a first input voltage signal in accordance with the temperature proximate the external surface of the tire, means for generating a second voltage input signal in accordance with the temperature proximate the internal surface of the tire, simulation network means having at least one resistor representative of the heat conductivity parameter of the tire and at least one capacitor representative of the specific heat parameter of the tire, the length of said network means being representative of the physical dimension of the tire, said network means receiving said first and second voltage signals and providing a selective output signal in accordance with the temperature of a selective point internally of the tire, means establishing said selective output signal as an exponential representation of the temperature of said selective point internally of the tire relative to a reference temperature, and integrator means for integrating said exponential output signal to provide a signal proportional to an equivalent cure factor.
