OPTIMIZATION METHOD OF CYCLOIDAL PIN GEAR TOOTH PROFILE CURVE BASED ON PRESSURE ANGLE by LI YouTang, DONG HaoNan

“…According to the theory of cycloidal pin gear drive,a method of tooth profile optimization based on pressure angle was proposed.The cycloidal pin gear tooth profile was divided into working section and non⁃working section.The factors that affected the pressure angle of the working section were modification parameters and design parameters.The influence of the two types of parameters on the pressure angle was discussed.With the two types of parameters as design variables and the average pressure angle of the working section as the objective function,the cycloidal gear of RV⁃550E reducer was optimally designed by determining the boundary conditions from the requirements of motion and lubrication.The results show that this method reduces the average pressure angle of the working section of the example by 4.14%,the maximum value of the pressure angle in the single tooth meshing process by 1.35%,the maximum Mises stress of the contact tooth pair before and after optimization by 20.77%,the occurrence position is transferred from the cycloidal gear to the pin gear,and the model mass reduces by 9.38%,which can ensure that there is no undercut phenomenon and obtain a good combined modify effect.…”

Study on Structure and Seepage Control Safety of Second-Phase Cofferdam in Datengxia Water Conservancy Project by ZUO Yongzhen, CHEN Liang, XU Han, LI Bo, CHEN Jinsong

“…The second-phase earth-rock cofferdam in the Datengxia Water Conservancy Project is one of the most important temporary buildings,and its design and construction reflect major key technologies of the Datengxia Water Conservancy Project.In order to ensure the safety of the second-phase deepwater cofferdam project,a special scientific research demonstration was conducted on the structure and seepage control safety of the second-phase deepwater cofferdam.In view of the difficulty in determining the density of the cofferdam formed by deepwater dumping and the feasibility of the anti-seepage system with a single anti-seepage wall connected to the geomembrane,experimental research was carried out through the centrifugal model test,so as to determine the underwater dumping density and angle of repose,the mechanical characteristics of cofferdam filler,the shear characteristics of the interface between filler and plastic concrete,and the characteristics of plastic concrete materials.The finite element analysis of stress deformation and the seepage stability analysis of the cofferdam were carried out,and the safety analysis evaluation and the section optimization design of the cofferdam were performed.The second-phase cofferdam has undergone two flood seasons of safe water retention operation,with a small total seepage flow,slight maximum settlement,and low horizontal displacement.The scientific research work has well supported the design requirements.…”
