Standardization Design Of Loading Pallet Components Using Finite Element Method

With the development of our society, more and more people owned themselves personal cars. Certainly, car brings many conveniences in our daily life. But it brings new problem, Such as the traffic and the accident. One of the biggest problems is the lacking of the parking place, there is so many cars that many car owners can't find place to shut down, especially in big cities. In the final analysis it is because the lacking of parking places and the increasing number of cars. To solve this problem, one approach is to prohibit people to buy car, but it almost ridiculous. The other way is to supply more parking place or parking equipment. But in most big cities, to provide large blocks areas is nearly impossible because of the limited land source and the high price of the land. One effective method is to provide the mechanical parking equipment. Mechanical parking equipment can provide more parking place in limited areas, because car can halt in the lower layers and the upper layers. In our country more and more company have realize the great benefit of producing mechanical parking equipment and take great effort to design this useful products. And more and more people choose to park cars on this new equipment. But some of them would like to shut down on ground if he has choice, because they still can't trust in this equipment, they don't think it is safe enough to halt on. It need designer to design the more safety and strong structure of it. But with the traditional design method it obviously can't accord with such situation. It needs new design method to create the product faster. This paper is to introduce an effective method: Finite Element Method. Because the loading pallet's deformation is bigger than 1/5 of its thickness, so the nonlinear solution is adopted in chapter two. Then in chapter three, the FEM model of loading pallet is created using ANSYS application, then compare the analysis result with the testing result, through comparison, to evaluate the correctness of the modeling method. Then the most effective modeling method will be adopted to redesign a new structure of the loading pallet. In chapter four, a new loading pallet is created according to the original structure, and an optimization of the structure is performed to the parametric structure model. In order to design the newly structure more convenient, a new GUI environment of new plate design is build in ANSYS. With the best optimization data and considering the stock/manufactory terms, the best structure of the loading pallet is finally established which has a lower weight and stronger performance. Then the new loading pallet is checked in different loading condition. It shows the new loading pallet is measure up in any real circumstance. At last, the connecting method of reinforcing steel bar is studied. The new loading pallet can be applied as the lift pallet and the move pallet. Using the GUI dialogue in ANSYS, the designer can created a new pallet with different length very easily. The realization of auto design environment and creation of the new structure save a lot of time and cost in the product process.
