Carton drop test is a kind of drop test. In the process of establishing or inputting carton model, the carton has the following requirements:
1. The density and elastic modulus of the material must be defined and ensure that the value cannot be zero, otherwise the program will not be able to calculate.
2. It is best to define damping options to eliminate numerical oscillations during the calculation.
3. It is best to avoid using triangular, tetrahedral, prismatic elements and small elements.
Experimental requirements for drop box test
1. The operation and implementation of the test requires a lot of manpower and financial resources, which increases the cost of the product.
2. The course of the test is very short, and it is difficult to observe the phenomena in the process of the test.
3. The test conditions (such as impact angle, etc.) are difficult to control, which makes the test repeatability very poor.
4. Generally, the test can only get the test results, and it is difficult to observe the causes of the phenomenon.
5. During the test, it is difficult to observe the internal characteristics and internal phenomena of the product, such as acceleration response.
