2.The bottom roller and sub-bottom roller of HCR is calculated about its equivalent stress, contact stress and the distributing of pulling-stress along the inside track of HCR.Also, effects of hollowness and pinch fit are analyzed on bearing stress and rated load.
3.High precision preloaded dual-V rolling guide ways are used to provide good rigidity.
4.A Simulation Method of Cascade Superheated Steam Temperature System using Smith Predictor with Load Feedforward Control
