Transport simulation in the vibration test stand
Pack goods safely: Vibration test and shock test

Large mail-order companies in particular know the problem only too well. Many packages suffer during transport and arrive damaged at the customer's premises. If the contents are then damaged, this is almost always at the expense of the sender. This is because they have to prove that the product arrives undamaged at the customer's premises. Many large mail-order companies and logistics companies rely on their own standards for product packaging. In the transport of goods, the specifications of the International Safe Transit Association (ISTA), the American Society for Testing and Materials (ASTM), the DIN EN ISO standards and other standardisation organisations are applied. Large companies such as Amazon, UPS or DHL often have their own standards. They specify the requirements that packaging must meet in order to withstand certain transport loads. On the basis of these specifications, Hänchen designs the required functional test stand individually.

The load test of the packaging is carried out using precisely calculated test methods that are simulated by means of a vibration test stand and shock tests. They are designed to realistically reproduce situations that arise during transport with a wide variety of means of transport and thus prevent transport damage. This includes vibrations caused by road transport, impacts and shocks caused by throwing packages or climatic changes, for example in winter when reloading from a warm warehouse into a cold transporter.

Testing, analysis and evaluation of the data obtained enables the design of product-specific packaging that prevents transport damage.

The special machine construction Ratio-Drive^® division from Hänchen offers simulation test stands according to the individual specifications of the customer. This can include vibration testing, shock testing, vibration and drop testing or compression testing. Consulting, engineering and implementation are all from a single source. Ratio-Drive^® means: The customer knows the process that the machine has to map, Hänchen builds the special machine. The individually configured software developed by Hänchen enables precise control of all test stand processes. Components such as hydraulic cylinders from our production or electrical drive solutions from other manufacturers can be used. The customer receives a customized, turnkey functional test stand that consists of powerful modules.

Shock test stands are used to simulate errors during handling during the transport process and are used to check product stability. Hänchen offers a lifting device here that simulates the drop height and force. Impact movements with high acceleration can be achieved using hydraulic cylinders. The test stands are always designed in accordance with the applicable machinery directive and implement the required protective measures. It must be taken into account, for example, that a test object can fall uncontrollably due to incorrect operation or technical failures. For example, a package weighing 150 kg quickly reaches a very high force on impact when dropped. A falling test object could therefore cause serious injury to a person.
