Sight-stabilizing mechanisms controlled by diaphragm springs and other damping elements is an important subordinate system of airborne sight stabilizing System. The performances of sight-stabilizing system depend on the characteristics of kinematics and dynamics of the system in a great extent. Among various external moments acting on the rod of the manipulator, such as those moments caused by damper, positioning spring, and restoration spring, the forces by diaphragm springs are most obvious. According to the structure form and motion peculiarity, the rod can be equivalent to a rigid body turning around a fix point. Simulation results reveal that the moment of the restoration spring to the rod is proportional to the angular displacement, and that the moment is the most prominent factor influencing the operating performances among all these moments. Through reasonable adjustments of structural parameters of the restoration spring, the performances of the sight-stabilizing system can be improved greatly; the analysis method provides a basis for guiding the design of concerned structural parameters of sight-stabilizing system.

Macro/micro mechanical arm is an important component of workover mechanical system. According to its composition characteristics and working principle, the arm was simplified to a plane system that all components were working in the same plane. Based on rigid body kinematics and dynamics theories, the kinematics and dynamics mathematical models of arm lifting progress were established by using constraint equations, rate equation, acceleration equations, virtual principle work, lagrange multiplier and differential-algebraic mixed equations of motion. It provides theoretical basis for kinematics and dynamics analysis of the macro/micro mechanical arm in lifting process.

This article presents a way to draw Euler angles such that the proper operation and application becomes immediately clear. Furthermore, Euler parameters, which allow a singularity-free description of rotational motion, are discussed within the frame-work of quaternion algebra and are applied to the kinematics and dynamics of a rigid body.

Establishing bias and central entity model of slider-crank mechanism in this paper, then the bias model is imported into the ADAMS for kinematics simulation, and we can get the sliders law of motion. Then using ANSYS and ADAMS jointly to establish the multiple rigid body and the coupled model of slider-crank mechanism, and carrying on kinematics and dynamics simulation analysis to compare the two simulation results. Through build simulation of the coupled model with UG, ANSYS and ADAMS, the result of this calculation is better to reflect the true movement of the mechanism.

Utilization of conventional energy sources such as coal, fuel oil, natural gas and others on the one hand has a low operating cost, but on the other side of the barriers is the greater source of diminishing returns and, more importantly, the emergence of environmental pollution problems dangerous to human life. This study aims to formulate the kinematics and dynamics to determine the movement of Solar Power Mower. In this study, using solar power as an energy source to charge the battery which then runs the robot. Design and research was conducted in the Department of Mechanical Workshop Faculty of Engineering, University of Hasanuddin of Gowa. Control system used is a manual system using radio wave transmitter and receiver which in turn drive the robot in the direction intended. Experimental results showed that treatment with three variations of the speed of 6.63 m / s, 8.84 m / s and 15.89 m / sec then obtained the best results occur in grass cutting 15.89 sec and high-speed cutting grass 5 cm. Formulation of kinematics and dynamics for lawn mowers, there are 2 control input variables, x and y ̇ ̇ 3 to control the output variables x, y and θ so that there is one variable redudant. Keywords: mobile robots, lawn mower, solar power
