Pressure Cycle Test Bench for Automotive Components

Product Details

For impact testing with subsequent long-term pressure and bursting tests, our systems offer two chambers in which up to ten tests can be done simultaneously at an ambient temperature of -60 °C up to 180 °C or at room temperature. Via separate control circuits, the medium Glykol is added to 100% or different oils – with a temperature from room temperature up to 160 °C. This makes it possible to carry out tests at very large differences in temperature, which are rare in real-life situations, even with curing tests on the Nürburgring, in the Siberian tundra, or in the deserts of Africa.

Various servo-hydraulic pressure boosters, which are optimally designed for each test area, allow very precise control of the pressure. Pulse-pressure tests can be performed with a frequency of 0 – 10 Hz (the norm is 0.5 – 2.5 Hz) with a trapezoid curve of 4 – 25 bar and 0 – 160 bar; In the sinusoidal curve with a frequency of 0 – 10 Hz, pressures of 0 – 6 bar are possible. The maximum burst pressure is 500 bar. Data acquisition and visualization is performed using National Instruments’ LabVIEW applications. All test sequences and data are automatically stored on the plant and can be exported to the network for evaluation.

Performance data:

• - 3 different load change tests

• - additional burst pressure test: up to 500 bar
• - additional leak test: up to 100 bar (long-term test)
• - Frequency: 0.5 to 2.5 Hz (up to 10 Hz)
• - Media temperature: RT up to +160 °C
• - Ambient temperature: -60 °C to +180 °C
