Our comprehensive range of testing solutions for test labs includes vibration test systems, shock test systems, .A drop tester is a specialized machine used to evaluate the durability of packaging against impacts, shocks, and drops during handling, shipping, and transportation. By lifting and dropping a test specimen from various heights and angles onto a hard surface, it simulates real-world conditions to observe and assess the impacts on different parts of the package.
During a free-fall drop shock test, the product is mounted to a test table. The acceleration amplitude and shape of the pulse are determined by two factors: the height from which the product is dropped and the impact surface material. The height determines the overall peak acceleration; the higher it is, the greater the acceleration when the . Our top pick for the best rugged laptop is the Getac S510 for its highly configurable options for shock, drop, moisture, and dust resistance as well as options for multiple storage drives .
Drop/impact protection is an important concern for the design of portable electronic products. Drop/impact forces may cause severe functional damage in form of component failure and/or .
SRS Shock SRS shock testing is commonly used to determine a test article’s ability to tolerate the mechanical stress waves produced by a high frequency, High-G shock event, such as rocket stage separations. SRS shock specs are found in most aerospace hardware test procedures, given as a graph profile showing “response” accelerationWhen performing an ASTM D5276 drop test, the impact surface must be: Horizontal and flat Built with concrete, steel, or stone; Durable enough not to deform under test conditions; A rigid mass equal to 50 times or more the mass of the heaviest sample being dropped; Sufficiently large so that the test sample falls entirely on its surfaceIn general, shock acceleration events may easily exceed 5,000 g or more with pulse durations of less than 10 ms (1 g = 9.80665 m/s2). Many test laboratories will shock calibrate each sensor before and after every test to check if the transducer survived and to validate the acquired data.

Mechanical shock tests have typical durations of less than one second per shock, although multiple shocks over longer time periods are commonly performed. Mechanical shock testing is also distinguished from thermal shock testing which is performed by very rapidly changing the temperature of the test sample. Typical Mechanical Shock Testing .
The AutoShock-II ™ is a fully automated series of shock test systems used to measure and identify product fragility levels and evaluate protective packaging. . manufacturers can systematically test and optimize product design and packaging. L.A.B. Equipment, Inc.’s fully automated computer controlled shock and data analysis test systems .This is ensured through a robust Quality Management System and Test Method Validation program. The drop test machine(s) should be subjected to an annual preventative maintenance program. The height of the drop should be confirmed with a calibrated ruler, ideally to an accredited reference standard. The impact surface used in testing should .International product transportation organizations are at the forefront of establishing crucial drop test standards to guarantee the safe and reliable transportation of goods. One such standard is the ASTM D4169 protocol, .
Test engineers needed to develop an impact test machine for automotive bumper testing. The bumper was required to absorb approximately 3,000 Joules in a designated crumple zone. Instron engineers modified their model 8150-drop tower shown in Figure 1. It is capable of generating 27.8 kJ of energy from a drop height of 96 in (2.4 m) and
During shock testing, products are subjected to a series of controlled impacts that vary in intensity and direction. These impacts can be delivered in different ways, such as drop tests or mechanical impacts, depending on the product being tested. Shock testing is used to identify weaknesses in products and to ensure that they meet safety . It took the B300 only 45 seconds to boot into Windows XP, but its score of 15.7 MBps on the LAPTOP Transfer Test was on the slow side--about 1 MBps slower than the mainstream average. Wireless .Conducting the Drop Test: A drop testing machine or a free-fall method is used to ensure precise and repeatable drops. The method of dropping (manual or mechanical) should align with the standard being followed. Inspection and Evaluation: After the drop test, the package and product are inspected for any signs of damage. The criteria for . The math may not reflect the actual test parameters. A typical shock test uses a half-sine or sawtooth waveform, which does not correspond to a constant acceleration model. Additionally, such shocks are highly dependent on the material of the part and the surface being hit. Without doing the full analysis, you may understress or overstress the .
