Tire temperature simulation method and device, electronic equipment and computer program product

The invention discloses a tire temperature simulation method and device, electronic equipment and a computer program product. The method comprises the following steps: acquiring a full-pitch pattern tire model of a to-be-detected tire; performing steady-state free rolling simulation on the tire to be detected by using the full-pitch pattern tire model to obtain a steady-state free rolling model; determining a heat generation rate model of the tire to be detected according to the steady-state free rolling model; the double-pitch pattern tire model is analyzed through a heat generation rate model, a simulation temperature field of the to-be-detected tire is obtained, and the double-pitch pattern tire model comprises any two adjacent pattern blocks in the to-be-detected tire, main body blocks corresponding to the any two adjacent pattern blocks in a tire main body and simulation units in the pattern blocks and the main body blocks; and heat generated by each simulation unit under the action of stress and strain
