Abstract：With the technique of wavelets analysis and neural network intelligence, aiming
at numerical calculation of temperature field in casting process of camshafts, t
he arithmetic of wavelet neural network is described. The solidifying temperatur
e of camshafts is tested by thermocouples, the data of specimens obtained by t
he testing results of temperature field is trained by backpropagation
neural network, the temperature distribution during filling and solidification i
s simulated. By contrasting the data of simulation with those of testing, the ma
ximum relative errors of simulation is 1.83%, and the theory basis is presented
for technological parameters.
