Ripple Signal Amplification: Measurement, Modelling and Mitigation
Use of high frequency ripple control signals for load control purposes has existed for many years. Although the level of the injected signal at the zone substation is generally small, amplification can occur when the network resonant frequency is close to the injected ripple signal frequency. Ripple signal level at the injection point is generally 5 – 7V in magnitude with reference to public lo...
متن کاملNumerical Study of the Effect of Materials’ Plastic Behavior on Equibiaxial Residual Stress Measurement Using Indentation
Indentation is a new method for estimating residual stress. The plastic behavior of the materials under study can affect indentation parameters and, thus, influences the results of residual stress measurement. In this paper, the effect of yield stress and work-hardening exponent on the accuracy of residual stress measurements in steels and aluminums was studied. Results showed that, for m...
متن کاملNumerical and Experimental Study of Residual Stress Measurement and Thickness Distribution of T-shape Steel Tube Produced by Tube Hydroforming
Tube hydroforming (THF) process is used to produce the complex components from the initial cylindrical tubes. In this paper, T- shape component was formed using a tube hydroforming machine and the residual stresses of hydroformed tube was determined by hole drilling method. Subsequently, the thickness distribution and residual stresses of final tube were investigated using experimental and fini...
متن کاملOverview Residual stress Part 1 – Measurement techniques
Residual stress is that which remains in a body that is stationary and at equilibrium with its surroundings. It can be very detrimental to the performance of a material or the life of a component. Alternatively, beneficial residual stresses can be introduced deliberately. Residual stresses are more difficult to predict than the in-service stresses on which they superimpose. For this reason, it ...
