Abstract: |
Recently, paper pulp is developed greatly in our country. As a new buffering material, it has occupied a great deal of market share through the packaging field and it is widely used in the buffering packaging of industrial production, such as the packaging of poultry eggs, fruits and electronic production. There are good prospects about it. But the current study on making pulp, forming equipment and processes in the pulp manufacturing process is a lot, while the product performance evaluation criteria and theory of structure design is studied little. Drop and impact of cushioning packaging products as well as performance of cushioning materials can be determined by physical tests. But such tests are difficult to control and the measured physical quantity is limited with high costs. In industrialized countries, the traditional drop test and performance testing of cushioning materials are increasingly done by computer simulation technology, which can be quickly and accurately to get the stress ,strain and other parameters, as well as animation of dropping the process. In this paper, ANSYS/LS_DYNA analysis software did a lot studies on simulation of parameters of pulp molding structure and material to lay the foundation of actual structure design of buffering package.
