| description | Thermecmaster-Z thermal simulator was used to carry out hot compression experiments on the metal material TB6 titanium alloy of exoskeleton robot at deformation temperature of 1 013 ~ 1 073 K and strain rate of 0,001 ~ 1 s<sup>-1</sup>, and the influence of deformation conditions on the flow stress of TB6 titanium alloy was studied. The multivariate linear regression constitutive model of TB6 titanium alloy was established by Arrhenius hyperbolic sine equation. The results show that the flow stress is significantly affected by the strain rate, and the influence of deformation temperature on the flow stress is related to the strain rate. The theoretical value of the peak stress obtained by the multiple linear regression constitutive model of TB6 titanium alloy is well fitted with the actual value, and the correlation reaches 98,11 %, which proves that the model has high prediction accuracy. |
