Finite element analysis techniques in the cell division

6639), but was much better fitted entity boundary. 5 run finite element analysis in finite element analysis, by using P-method technology cell stress gradient and contour of the fitting also has a great advantage, the following examples Case 2 by a simple comparison. In the H-method technique, each element of the stress-strain finite element equations are also linear equations, quadratic equations, or at most three equations, and in the P-method technique, each element of the finite element equation of the stress-strain high-order polynomial. Thus, while non-adaptive H-method technique Ge 4 of the finite element mesh unit smaller in larger quantities, but the stress profile with the model fit was not good enough, and the P-method adaptive finite element techniques to draw larger grid cells, the small number, but the stress profile with the model fit very well, can be very precisely fit the large stress gradient, and automatic convergence solution, which can ensure the accuracy and efficiency of computation. Analysis using H-method and P-method shows that the two technologies cloud stress,[link widoczny dla zalogowanych], the tension in the 3000kN, the stress range in 5 ~ 751.3MPa, maximum stress regions are the same. But the two kinds of technology, the difference is,[link widoczny dla zalogowanych], non-adaptive H-method technology than the P-method adaptation of finite element mesh technology units set aside the small number of larger, while the P-method adaptive technology than non-adapted of the H-method technique to draw the finite element mesh element stress contours and the model fit better, we could very accurately fit a large stress gradient. 6 Conclusion The model of finite element analysis, need to build physical models to determine the material's mechanical properties, the constraints and stress analysis, cell division, and finally run the analysis and display results. Cell division of the finite element which is critical technologies. The adaptive P-method technique to draw the finite element mesh unit and model entity boundary and stress contour fit very well in finite element analysis have a greater advantage. * References: [1] bundle of virtues.

Received Date: 200r7.12-05 $%$$${$ flexible energy-absorbing cushion device block cars Yanzhou Mining (Group) Company developed RHXL Dongtan coal mine type of flexible energy-absorbing block car buffer device for a variety of in-depth control of large and medium-sized Inclined hoist, hoist and gear to achieve a long-range synchronous linkage car device control and stop vehicles damaging the small, high degree of automation. The results of using two cars blocked Pa 7mm rope as a column, the buffer distance of 2 ~ 3Ill, absorbing energy in the form of flexibility, cushioning and friction, the cylinder is t ~; moo × 2OOO-G type, working pressure of 0.1 ~ 0. 8MPa. When the winch promotion or devolution of cars blocked field harvester is at open position, the depth indicator mounted on the block to the location on the touch switch is closed, the cylinder block car field to enhance contacts normally closed solenoid valve off, normally open contact closure, electromagnetic valve action commutation, the cylinder piston rod retracted, block car bar lift. When the bar reaches full stop when the car, put car in gear the magnetic field on the disconnect switch normally closed contact, normally open contact closure, block car off the red bar lights, green light, indicating the block car bar is open, run Harvesters can safely stop vehicles through the column. When running tub safety bar through the windshield after the depth indicator installed in the block release position on the touch switch contacts, block car field to enhance the normally closed solenoid valve cylinder contact closure, normally open contacts off,[link widoczny dla zalogowanych], the cylinder piston rod, bar down windshield to prohibit the tub running.
