Test the stress of components in the dishwasher

<

The home appliance industry requires shorter development time and lower development costs. Therefore, in the development process of the product, the use of 6=>, such as fall simulation, computer-aided engineering / method becomes more and more important. However, the traditional 6=> tools and methods are based on the material properties of steel and other metals. Compared with metals, plastics have greater viscoelasticity and viscoplasticity, and in the usual 6=>, these properties Not enough to get enough reflection. Currently, due to the lack of data on materials at high strain rates, most fall simulations use material data under quasi-static test conditions. Usually, the simulation results are not ideal when used to deal with polymer behavior under conditions of high stress, high strain rate or high load rate. In actual use, components are placed under a variety of load rates, from low loads to static loads to high-speed impact loads.

Generally, under high strain rate conditions, thermoplastics may become hard and fail due to relatively small stresses. So we need to obtain material data for strain rate and temperature changes, and the university has developed a method for determining material data at high strain rates, which is a reliable basis for calculations and simulations. Inspection of material data reliability To test the reliability of the above material data, the injection molded parts were tested. Record the relationship between the force and time under the dynamic load of the box. The actual deformation is then compared to the simulated results of this part under dynamic loading. We can see that there is a strong correlation between simulation and real deformation. Material samples can be calculated after obtaining such good test results to ensure the reliability of the calculation.

The calculations determine the stress on each component in the dishwasher. Simulating and investigating the movement of the plastic melt as it is injected into the mold or cavity is a very effective means of allowing us to clearly see how the melt is injected into the mold or cavity. We require balancing the melt flow to prevent overfilling of the material in the mold, which can otherwise lead to injection molding defects. In the usual practice, the direction of movement of the melt as it is injected into the mold or cavity is not readily observable, especially for complex components with different wall thicknesses. Molten plastic usually flows in the direction of least resistance. An animated representation based on the results of the calculations is presented, the results of which represent the path of the melt flowing through the part. "Conclusion This project uses a dynamic numerical simulation method when designing the main force-receiving part of the dishwasher using the new polypropylene material. The inner barrel can be tested on the computer without actual test, and all the test results are It is satisfactory. The parameters necessary for the material are also successfully determined.
