The two modules connected institutions with together, stress the worst part is two docking rotating arm. A rotating arm as an axis, and have a connecting holes, therefore, we connect to the vertical stress analysis of mechanism of connection. Chart shown, 3.9m 2.10 connection when connecting two single diagram.
As shown in figure 2.10 respectively, the axis connecting holes and the ball bearing, were only draw a ball, and connecting holes are only a part of the function with a ball, the calculation to the corresponding power based on the superior to 3. Set of modules for connecting shaft center of gravity, the sales of chamfering, as a ball, the pressure exerted to pin to pin a ball pressure imposed, are:

For the cylinder pressure gas pressure, the counter for a ball, which is a ball writing.i imposed connection of the inner pore pressure, combined with the horizontal axis Angle for connecting holes on wall, a ball pressure, apparently, the:

Thus, when taking the actual maximum and minimum value when, it is the smallest of the air pressure required. Practice is fixed, so this module can bear the weight is limited. When the weight of the module, also increases with increasing, but the reality is, so I need to increase, and connection of inner pore pressure to force will also increase the ball, but due to the constant pressure to the ball, pin, since such pressure balance of the ball, those who change, which means the ball may sell out along the bevel, making connections with the axis of the hole, locking mechanism to unlock, two module is returned. Therefore, when the module weight increases or interference to join the organization of force increases, the reliability of the connection will decrease.

Note to figure 3.10 (a), (b) and figure 2.9 (a), (b) is different, so the type (3-4) with (2-4) is different; (3-4) for new connection, pin imposed by the pressure and ball screw writing.i vector and the ball is to connect hole wall pressure and type (2-4) shows that both the vector is pressure, it shows that the new connections to pin put the ball pressure is also used to balance the gravity and old connection was just is used to increase the gravity separation connection, this is the difference between new connection. For new connection, when the weight of the module, also increases with increasing, but due to balance and the reliability of the connection, so will the institutions to higher than the original one.

The male hard dual purpose diagonal cable bridge diagonal cable bridge anchor area the general diagonal cable bridge stress more centralized, the structure is more complex than, is the control design essential spot. Must grasp the anchor area the stress distribution, not only must conduct the research through the model experiment to it, moreover also must conduct the finite element analysis research to it. The finite element analysis finally not only uses in to instruct the model experiment, moreover may conduct the parameter analysis research, makes up the model experiment the insufficiency, reduces the research expense. The Wuhan day is popular the continent bridge collection new technology, the new structure, the new craft, the new equipment "four new" the technology to a body, is in the present world the span biggest, the carrying capacity heaviest male iron dual purpose diagonal cable bridge, in the design and the construction must carry on the system to the anchor area stress characteristic the analysis research, in order to causes the structure reasonably, the implementation effect is better. This article namely is popular the continent bridge take the Wuhan day as the actual project background, use large-scale general finite element software ANSYS to the bridge rope tower anchor area, the rope Liang anchor area as well as the highway bridge kneading board steel mixes the adapter section to carry on the finite element computation analysis, main work content and achievement as follows: (1) establishes the entire bridge static analysis model using ANSYS, calculates various node control endogenic force the influence line, obtains under the live load function various node control endogenic force maximum value as well as if corresponds other various members the endogenic force displacement value, is the partial nodal analysis provides the correlation data. (2) to the rope tower anchor area selection appropriate boundary condition, establishes the three-dimensional space finite element analysis model using ANSYS, calculates the rope tower anchor area the stress field distribution situation, and the analysis influence anchor area security performance primary factor, proposed the improvement local stress distribution concrete measure, and draws the corresponding conclusion.

Through is popular the continent bridge to the day the rope tower anchor area, the rope Liang anchor area as well as the highway bridge kneading board steel mixes the adapter section the computation analysis, draws some valuable conclusions, to the next similar bridge anchor area design, the construction will have the certain instruction significance and the reference value. 这只是按字面去翻译的 可能有很多的错误 望理解
Rail composite cable-stayed bridge cable-stayed bridge anchorage area cable-stayed bridge over the general subject of a more focused, more complex structures, Control design is a key component. Anchorage to grasp the stress distribution, not only through its model tests to study but also its finite element analysis. Finite element analysis is not only used to guide model experiment, and the parameters can be analyzed, to make up for the test model, and reduce costs. Wuhan Bridge-day set of new technologies, new structures, new technology, new equipment, "four new" technology in one. is the world's longest, most heavily truck, rail-cum-road bridge, Design and construction have to anchor the force characteristics of the system analysis, in order to enable a more rational structure, results are better. This paper is day-to Wuhan Bridge practical engineering background, use of large-scale general-purpose finite element software to bridge the anchorage zone, REQUEST anchorage area highway bridge decks and steel combination of mixed finite element analysis, the main elements of the work and the results are as follows : (1) using ANSYS-wide bridge static analysis model Calculation of the internal forces control nodes in line, come under live load of the control nodes and internal forces with the maximum corresponding to the other rod displacement of the internal forces of value Local nodes for data analysis. (2) of anchorage zone choosing appropriate boundary conditions, using ANSYS 3D finite element analysis model anchorage zone calculation of stress distribution, and analysis of impact safety anchorage zone of the main factors improving local stress distribution of specific measures and draw the corresponding conclusions. (3) on the highway bridge deck steel-concrete composite parts, a three-dimensional finite element analysis model Study steel mixed with parts of the distribution of stress field, the evaluation of the site by the behavior and safety performance. (4) the most disadvantaged anchorage zone, a 3-D finite element model anchorage zone calculation of stress distribution, and study detailing the corresponding field distribution. Through the day-Island Bridge anchorage, cable anchorage area highway bridge decks and steel-concrete composite analysis of the calculation, draw some valuable conclusions on the future of similar bridge-anchor the design, Construction has certain guiding significance and value.
