Diagnostic method for silicone rubber aging status based on ultrasound velocity
Electrical cable joint silicone rubber insulation is influenced by various factors such as electricity and heat,leading to aging and failure of insulation performance.For non-invasively assessing the aging condition of sili-cone rubber,a diagnostic method centered on ultrasound velocity to determine the aging status of the material is proposed.Silicone rubber specimens with varying aging durations were prepared,and their density and elastic mod-ulus were meticulously measured.The correlation between silicone rubber ultrasound velocity and aging status was verified through simulation and experimentation.The experimental results showed that the goodness of fit between silicone rubber velocity and aging status was above 0.8.Using ultrasound velocity can accurately characterize the aging state of silicone rubber.
