This article takes the two-stage screw type solar array which has multi-deployment and lock function as a study object, and simplifies the joint hinge as rotation vice according to the transmission order of multi-deployment and lock joint hinge. Based on the kinematics characteristic analysis of solar array's deployment and the Kane dynamic equation, the dynamics analysis model of solar array's deployment...
In this paper, the spatial six-DOF(degree of freedom) parallel manipulator is described as a rigid body, and in many cases, this simplification is adequate for describing the properties of the whole mechanical system, especially with large and heavy motion system. By using Kane approach the explicitly forward dynamic equations with six variables are gained straightly and readily. Under identical conditions,...
The financial crisis which sweeping the whole global has destroyed many enterprises to extinct, But there are also companies in the wake of the financial crisis become the more powerful, the reason is that the dominant force of innovation promotes the enterprise sustained development and growth. The effect of the dominant force of innovation make the dynamic energy and potential energy of company's...
A dynamic response of liquid microlens using dielectric force was demonstrated using comparison between experimental and simulation results. The theoretical results of the simulation match fairly well with the experiment in liquid microlens with a diameter of 500 μm. An high speed motion camera with a speed of 3000 fps was used to capture the images of dynamic response for 500μm, 2mm and 5mm droplets...
The most important characteristic of a vibration isolator are its natural frequency and load supporting capacity. The vibration isolation quality in low excited frequencies (input frequencies) is considerably improved by reducing the natural frequency of system. In this way, however, load supporting capacity of a linear vibration isolating system can not maintain without an increase overall dimensions...
Contact bounce of relays, which is the main cause of electric abrasion and material erosion, is inevitable. Using the mode expansion formalism, this paper presents an analytical investigation of the dynamic behavior of two different reed systems configurations. The model uses dynamic Euler-Bernoulli beam theory for cantilevered beams, includes the driving force from the electromagnetic systems, and...
