Koormusdoos

Koormusdoos is a modular device used in engineering test environments to apply known loads to a specimen or system under evaluation. The term is used in Estonian technical literature and informal discussions to describe a container-like module or assembly that introduces controlled force, weight, or pressure into a test setup. A koormusdoos typically consists of one or more load elements, such as calibrated weights, hydraulic or pneumatic actuators, or electromechanical rams, housed in a safe, rigid frame. The device interfaces with a data acquisition system and load sensors to measure the response of the testing object and to verify the applied load.

Operation involves selecting a load module or combination, mounting it to the test rig, and initiating the load through an actuator controlled by software or a manual control, while monitoring load indicators and safety interlocks. Modern koormusdoos may offer rapid-change modules for different magnitudes and directions of load, as well as dynamic loading capabilities to simulate vibrations or shocks.

Applications include material testing, structural engineering, automotive and aerospace component validation, and educational demonstrations. They are used with universal testing machines, servo-hydraulic rigs, or hydraulic presses, and must comply with general safety and calibration standards. Variants emphasize static loading, dynamic loading, or multi-axis loading, and can be standalone units or integrated into larger test systems.

In summary, a koormusdoos is a practical tool for applying controlled loads to a specimen, enabling reproducible experiments and quality assurance in engineering contexts.
