Reliability drop test, shenzhen reliability drop laboratory.
Drop test also known as "packaging drop test machine," for the product after packing in the simulation of different edge, Angle and surface in different heights fell on the ground, to understand the product damage and evaluation of product packaging components can afford to fall when the drop height and the resistance to impact strength.In order to improve the packaging design according to the actual situation and national standard.Usually the drop height is based on the weight of the product and the probability of falling. The surface should be a smooth, rigid surface of concrete or steel.
80% of the damage was falling, from collision of electronic products, developers tend to spend a lot of time and cost, the quality of the products against doing related test, falling test is one of the most common structure and impact test.This method is reliable, but it also has many shortcomings, mainly manifested in:
1. The operation of the experiment requires a large amount of manpower and financial resources to increase the cost of the product.
2. The process of the experiment is very short, and it is difficult to observe the phenomenon during the experiment.
3. The conditions of test test (such as collision Angle) are difficult to control, which makes the test repeatability very poor.
4. The test results can only be obtained, and it is difficult to observe the cause of the phenomenon.
5. It is difficult to observe the internal characteristics and internal phenomena of the product, such as acceleration response, etc.
By using LS - DYNA before the product is opened, the simulation and simulation of it can solve the above problems well.Compared with the traditional test method, ls-dyna has the following obvious advantages for its virtual simulation:
1. Reduce test times and test costs.
2. The changes of various physical quantities of the whole falling collision process can be visualized dynamically.
3. Not only can observe the external characteristics and phenomena of products, but also observe the internal characteristics and phenomena of products.
4. The boundary conditions are convenient to control, and the simulation repeatability is good.
5. Early design simulation can detect the characteristics of the product and reduce the problem.
The fall test procedure usually follows the following steps:
1. Preparation of sample before test.
2. The function, safety and appearance inspection of the product shall be tested before the test, and the drop test can be conducted after the normal operation.
3. The samples shall be packed in accordance with the prescribed methods (refer to the production instructions or specifications), and the accessories shall not be omitted.
4. If there is a special requirement for the sealing box (such as the belt), it shall be carried out according to the requirements. If there is no special requirement, the package box shall be sealed with 2-inch transparent adhesive paper, and the carton box shall be sealed with 3-inch transparent adhesive paper.
5. The test samples shall not be less than 2 full boxes or 4PCS finished products.
6. Descending order.
7. The base Angle of the seam.
