In this article, the horizontal hinged heavy duty servo cylinder is taken as the research object. In the actual working process, while the servo hydraulic cylinder outputs the curve force, the cylinder body will also rotate with the hinge point to a certain extent. Because the position of the center of gravity is constantly changing, and the weight of the cylinder body is too large, the friction causes damage to the sealing structure and seriously affects the working efficiency of the equipment. In order to improve the sealing performance of the servo hydraulic cylinder, a corresponding study is carried out. Firstly, the working angle interval of servo cylinder is optimized to ensure that the friction is the least in this range. Based on this, a new supporting structure is proposed, in which a small hydraulic cylinder is installed at the bottom of the servo hydraulic cylinder body. By controlling the output force of the small hydraulic cylinder, the cylinder body and piston rod are aligned all the time. The servo cylinder body is flexibly processed to more realistically see the adverse effect of the friction, and the co-simulation method using MSC.ADAMS and MATLAB/Simulink verifies the new support structure to improve the sealing performance. According to the simulation results and experiment results, and combined with the deformation curve of the hydraulic cylinder, when the maximum displacement is 336 mm, the maximum rotation angle is 15.6°, the friction is the smallest, about 5801.9 N. It is known from the experiment results that after adding the new support structure, the frictional force is reduced to 1365.9 N, which reduces the friction of nearly 76.5%.

“…As the drill point grinder does not need a big workspace, while requires the dexterity to enable the grinding motion of twist drill, a parallel mechanism-based structure is a good candidate for the drill point grinder. Those drill point grinders have been reported based on parallel mechanism such as Stewart platform in [29] and 3-PRS in [30]. Zou proposed a parallel drill grinder scheme and analyzed the kinematics, which will be studied in this paper [31].…”

A modeling method is presented for grinding of the designated geometrical parameters of twist drill in a Biglide parallel machine, which has the more effective and economic potentialities for grinding of drill point. The grinding kinematics trajectory and condition are analyzed based on the structure of the Biglide parallel machine. Moreover, the mathematical model of twist drill flank are derived and used to develop the parametric models of twist drill based on the grinding parameters of the Biglide parallel machine. The optimal grinding parameters are obtained for the custom-oriented twist drill using genetic algorithm. The grinding experiment results using the optimal grinding parameters agree well with the designated geometrical parameters of twist drill and show a marked improvement in grinding precision of the drill point in the Biglide parallel machine, depending on the customers' demands.

Based on the kinematic model with Cartesian structure, Newton-Euler like algo¬rithm being employed to solve the nonlinear equations of motion and constraints in real-time application, and dynamic multibody simulation, a novel integrated design for a 6-DOF ro¬bot is investigated, and the interfaces required for the implementation of different computer aided engineering (CAE) tools used in the design is addressed [1].The presented method in this paper was analyzed and verified by the numerical and physical 6-DOF robot model, the result shows that the topologic projection me-thod [2] is stable. The design experience accumulated will be very useful for the future product de-sign.
