This paper presents the multi-roller contact roller-gear cam reducer. It’s a special kind of the indexing roller-gear cam that changes the stopping stage of the indexing cam to zero and chooses the equal-velocity law. And with multi-roller contact the carrying capacity is greatly improved. In this paper, we created the 3D solid model of the main components of the reducer: the cam, the turntable and the rollers. After that, we used the FEA software ANSYS Workbench to calculate the static structural behavior and the results showed us the weak or dangerous part of the mechanism so that we can optimize the structural. However the static structural behavior does not always shows the working condition. Thus we calculated the flexible dynamic behavior of the reducer and it showed us vividly that which part is weak and we could see the real deformation and stress distribution of the structural while working. Then we can pay more attention to these parts.

The processing performance is closely related with dynamic performance and the dynamic performance is one of the most important performance indicators which is affecting the performance and product quality. The machine is affected most by the dynamic performance of machine bed. The modal analysis method is used to analyze the dynamic performance of the machine. In this paper, the modal analysis of lathe bed is conducted. A 3D solid model of HTC100 NC lathe bed is built with SolidWorks. In order to facilitate the finite element analysis, the model of lathe bed is simplified. The modal analysis of lathe bed is calculated with ANSYS Workbench 12. The first six natural frequencies and corresponding modes are obtained through modal analysis of the lathe bed. According to the low-order natural frequency and modal vibration shapes, the rigidity vulnerable area of lathe bed is realized, which provides the reliable theory to improve lathe bed structure.

. The corrosion damage data are obtained through the pre-corrosion accelerated experiment which is performed under three different time levels: 24h, 48h and 72h. Based on the corrosion damage data, a three-dimension (3D) solid model is created by CAD. An analysis procedure is developed using CAD and finite element analysis to predict stresses and residual strength due to corroded pits. The residual strength results of specimens are obtained from the model based on the corrosion damage data. The simulation results are compared with the true testing static intensity results and the method is proved that it is reliable and effective in engineering.

Metal cone of the screw rotor and stator rubber bushings are the two main components of the opposed biconinal cone screw hydraulic pump for the seawater. The stator rubber bushing is not only a damageable element, but also the key component deciding the service life and efficiency of the pump. Up to date, none effective method has been found for testing the deformation and enforced state of the stators rubber under the real working condition. For the general conventional screw stator with uniform internal pressure at both ends of the stator bushing enforced and deformed almost the same, as to other case when the cone screw pump stator has rubbers with different cross-sectional size and thickness at its different end, the enforcing and deforming state at different end varies differently. The stator of the opposed biconinal cone screw hydraulic pump is studied in this paper for the case when the stator is uniformly enforced, using finite element analyzing software ANSYS-Workbench , this study concluded the stress, the strain and inner-figure deformation of the screw hydraulic pump stator, the stator rubber and the stator steel thimble. Besides, the characteristics and rules of opposed biconinal cone screw hydraulic pump deformation are summarized as well.
