Material Testing is a crucial step in product testing, failure analysis, and R&D. It allows for understanding of how a product will react to certain stresses, as well as provide a testing baseline to ensure a product performs within specifications. Many of these tests are based on applying specific stresses to a material or object, and cycling this stress over time to determine fatigue rate, time to failure, and conduct Highly Accelerated Lifecycle Testing.
In the past, the technology for conducting this was primarily either hydraulic or electromagnetic. Hydraulic systems were powerful but slow, and electromagnetic systems were considered relatively fast, but even these systems typically had maximum frequencies of 3-5kHz.
High power actuators are used to test and manufacture better products.
To improve upon this, high force piezoelectric actuators that can provide up to 70 kN of force and cycle at up to 50 kHz. This means they provide testing up to 10 times faster than standard electromagnetic shakers, while simultaneously providing more force than the majority of other options. hpower high-power actuators are small – between 7 and 32 cm in length and a maximum of 4.5 cm in diameter. This makes them versatile and easy to integrate into test set-ups and tight spaces. Piezoelectric actuators also by nature are highly efficient, especially compared to electromagnetic shakers, so they consume drastically less power to operate and can be plugged into a standard wall outlet. Actuators are faster, stronger, more versatile, more efficient, and easier to integrate into testing spaces than most traditional shaker and fatigue testing systems. This has enabled end users in variety of industries, including:
- Material Testing Labs
- R&D Laboratories
- MEMS and Electronic Components
