Research on Application of Double Wing Package Drop Test Equipment in Product and Package Drop Impact Testing

Abstract:
In the modern logistics and transportation system, products and their packages are prone to drop impacts during handling, loading, unloading and sorting processes, which may lead to damage and functional failure. Double Wing Package Drop Test Equipment is the core testing device to simulate such working conditions and conduct drop impact tests. Taking LISUN DT-60KG Double Wing Package Drop Test Equipment as the research object, this paper elaborates on its working principle, structural characteristics, technical parameters, applicable standards and test procedures. It analyzes the equipment’s functions in simulating actual drop scenarios, inspecting product impact resistance and optimizing package design. Combined with technical specifications and practical test cases, the paper demonstrates its application value, providing references for quality inspection and product optimization in the electronic appliance, logistics packaging and other industries.

1. Introduction
With the rapid development of e-commerce logistics and commodity circulation, various electronic products, daily goods and industrial finished products are circulated more frequently. Unexpected drops often occur during manual handling, mechanical loading and unloading, as well as express sorting. The resulting violent impact will damage product structures and outer packages, causing economic losses. According to logistics industry statistics, cargo damage caused by drop impacts accounts for more than 60% of total logistics losses. Therefore, conducting standardized drop tests to verify the impact resistance of products and packages has become an essential procedure for manufacturers and testing institutions.

Featuring symmetrical double cantilevers, synchronous release and adjustable drop attitudes, Double Wing Package Drop Test Equipment can accurately reproduce free drop conditions at set heights and postures. As a typical model of this type of equipment, LISUN DT-60KG fully complies with multiple domestic and international industrial standards. It can perform comprehensive drop tests on surfaces, edges and corners, and is widely used in factory inspection and third-party certification for electronic appliances and finished packages. It is of great significance for quality control and package protection design improvement.

2. Overview and Working Principle of Double Wing Package Drop Test Equipment
2.1 Basic Definition and Functions
Also known as double-arm free drop tester, Double Wing Package Drop Test Equipment adopts a symmetrical double cantilever structure. Different from single-arm models, its two test arms can lift and release synchronously, effectively preventing samples from offsetting and tilting during the drop process. It ensures the drop posture and stress state fully conform to preset conditions and realizes standard free drop impact tests.

The core function of the equipment is to simulate drop impacts of products and packages during transportation, handling and loading & unloading. It completes high-precision free drop tests at specified heights and postures, so as to objectively evaluate the structural strength of products and the protection performance of packages, and verify the rationality of package design.

2.2 Working Principle
LISUN DT-60KG Double Wing Package Drop Test Equipment is driven by an electric lifting mechanism. Before testing, operators adjust the distance between two test arms according to sample dimensions, and place the sample stably on the double wing support structure. Then set parameters including drop height and drop posture (surface, corner, edge). The electric system lifts the sample steadily to the designated height and locks the position without shaking. Once the test starts, the special quick-release mechanism releases synchronously. The sample falls freely without dragging, swinging or secondary contact, and impacts the rigid test platform vertically to restore real drop impact conditions. After the test, operators check the appearance, structure and function of the sample, record test data and judge the impact resistance of products and packages.

3. Technical Parameters and Structural Advantages of LISUN DT-60KG Double Wing Package Drop Test Equipment
3.1 Main Technical Specifications
LISUN DT-60KG is a standard Double Wing Package Drop Test Equipment with excellent testing accuracy, load capacity and wide applicability. Its core parameters are shown in the table below:

3.2 Structural and Performance Advantages
• Symmetrical double wing structure with high stability: The double test arms operate synchronously to share load evenly. Compared with single-arm equipment, it avoids sample tilting caused by unilateral stress, ensures vertical drop trajectory and guarantees repeatability and accuracy of test data.
• High-precision positioning and release: Equipped with LED digital height display to eliminate manual reading errors, and the height tolerance is controlled within ±10mm. The high-response release mechanism enables pure free drop without external interference.
• Wide compatibility: The adjustable arm spacing and multiple drop postures make it applicable to cartons, electronic products, small household appliances and other samples to meet diversified test requirements.
• Robust and durable body: The integral rigid impact platform meets the requirements of relevant national standards for flatness and deformation. The overall frame features strong load-bearing capacity and is not easy to deform after long-term continuous operation.

4. Applicable Standards and Test Procedures

As the core domestic standard for package drop tests, GB/T 4857.5-1992 stipulates that the impact platform shall be an integral structure with height difference no more than 2mm. This equipment fully meets the requirements and can be used for statutory inspection of transport packages.

4.2 Standard Test Procedures
• First, sample pre-treatment: Regulate temperature and humidity of test packages in accordance with GB/T 4857 series standards to keep samples in actual service state.
• Second, equipment commissioning: Check the operation of double wings and flatness of the impact platform, and adjust arm spacing according to sample sizes.
• Third, parameter setting: Set drop height, posture and test times on the control system.
• Fourth, sample placement: Put the sample steadily on the double wing support and ensure firm placement.
• Fifth, test execution: Operators move to safe areas and start the equipment to complete the drop test.
• Sixth, result evaluation: Inspect the appearance, structure and internal conditions of samples after tests, record damage status and issue test reports.

5. Practical Application and Value of Double Wing Package Drop Test Equipment
