Test chamber for combined tests with 4-poster system

4-poster systems – also known as 4-post systems – comprise four actuators which simulate different road surfaces and the vibrations and impact loads resulting from these. Hydraulic systems are used for performance, stability and power tests and electrical systems for examining noise emissions. If the test requirements also call for different environmental conditions, the test chambers from weisstechnik are the optimum solution. These types of tests allow for the testing and validation of damping and suspension systems during the development process as well as end-of-line tests (squeak and rattle tests).

Perfect integration of the 4-poster in the test chamber takes place through close cooperation with the manufacturers of road simulation actuators. With our concepts for 4-poster systems, you can test all types of two- or single-track vehicles.
