ACCURATE PERFORMANCE ANALYSIS OF SINGLE AND MULTI AXIAL IMPACT OF MATERIALS AND PRODUCTS

For mono and multi axial impact tests

General description

The DW 1000 is a drop tower test system that performs mono-multi axial impact tests on products and specimens. The system allows to set impact energies ranging from 5 to 750J, allowing to test a wide range of products and materials, also thanks to the large volume of work available for the positioning of the sample.
The DW 1000 allows to perform both broken / not broken tests and instrumented tests, in which acquires strength and energy absorbed during the impact.
The system is developed to be easily customized and upgraded in order to meet current and future requirements of the client.
All versions of DW 1000 are equipped with a direct reading of speed, automatic recovery and positioning system of the weight.
A wide range of standard accessories is available. For special requirements STEP Lab is ready to collaborate with the customer.

  • Testing of products (i.e. equipment and ski boots, snowboards and skating; automotive components)
  • Uniaxial and multiaxial tests on specimens (i.e. impact test according to ISO 6603-2, ISO 7765-2, ASTM D 3763, ASTM D 3029 (Method B), ISO 8256 A, CAI test Boeing BSS 7260 and Airbus AITM 1.0010, Charpy ISO 179 an d ISO 148-1 test (other test upon request)

Features

  • Wide and accessible test area up to W 1400 x D 1400 H 650 mm
  • Easy to use thanks to an intuitive user interface
  • Test management via software
  • High security due to the blocking system of the doors activated when the test starts
  • Pneumatic system for the release of the drop weight
  • Automated lifting and positioning of the weight
  • Drop height varying from 0,05 to 1,4 m, set via software
  • Impact velocity from 0,2 to 5,0 m /s (up to 20 m/s with spring preload system)
  • Weights from 0,5 to 10 kg, for a total of 70 kg
  • Acquisition of impact velocity at 200 kHz
  • Aquisition rate (load signal) up to 3,5 MHz
  • Designed for integration with many accessories
  • Rapid transition from ISO to ASTM test rigs and vice versa
  • Easy integration with climatic chamber
  • Wide variety of grips, dedicated test accessories
  • Integration with both strain gauge and piezoelectric load cells

Advantages

Reliable test results, the robust chassis absorbs shock and vibration providing more accurate results

Robust guides make the drop weight towers ideal for component testing

The modular structure allows a wide range of applications

Direct reading of the speed and automatic recovery and positioning system of the impactor

Starting from the basic mechanical and software structure of the machine, further accessories for impacts on all types of components can be easily realized. Below are the accessories currently in the catalogue:

ANTI-REBOUND SYSTEM IMPACTOR

The debounce system holds up the drop weight thus preventing further secondary impacts affect the physical state of the sample / product.

SYSTEM FOR HIGH ENERGY IMPACTS

Spring preload system allows to increase the speed of the impact (the management of the module is fully automated)

CLIMATIC CHAMBER REFRIGERATION CIRCUIT

The drop tower can be equipped with a refrigeration circuit climatic chamber for temperatures from -40°C to +180°C. The cell management is integrated in the fall tower software.

CLIMATIC CHAMBER LIQUID NITROGEN

The drop tower can be equipped with a nitrogen climate cell for temperatures rane from -80°C to +180°C. The cell management is integrated in the fall tower software.

SUPPORT FOR BOOTS

  • The ski boot support is designed for testing ski boots, but is also suitable for testing other footwear that may be subject to impact during use (i.e. mountaineering boots, climbing boots, ice skates, safety shoes).
  • The angle adjustment allows to impact at various points of the footwear.

SUPPORT FOR SPECIMENS

  • Support and impactor for multi-axial test specimens ISO 6603-2, ISO 7765-2, ASTM D 3763, ASTM D 3029 (Method B)
  • Support and impactor for specimens for mono-axial tests (tensile) ISO 8256 A
  • Support and impactor for pre-damage testing for CAI test Boeing BSS 7260 and Airbus AITM 1.0010
  • Support and impactor for Charpy ISO 179 test and ISO 148-1
  • Support and impactor for testing of metallic materials: Pellini test: ASTM E208, Tear test: ASTM E436, API 5L3, EN 10274

STEP Lab is flexible in the production of specimen supports for any type of standard or custom.
