Four poster test
WebClimatic 4-Poster Shaker. The four-poster shaker encompasses a traditional four-poster design situated in a fully climatic chamber. It tests products with four single-axis vertical actuators that move in an up-and-down motion. It can be programmed to simulate any condition such as a gravel road, high-velocity pot holes or jarring drop simulations. WebThis study estimates difference thresholds for ten automotive engineers seated in a vehicle on a 4-poster test rig. Participants were exposed to multi-axis vibration. Component ride values were calculated by applying BS 6841 frequency weightings and multiplication factors to seat accelerations in the six directions. Difference thresholds were ...

A 4-poster or four poster automotive test system is specifically designed for the testing of vehicles (cars, trucks). These test systems consist of 4 hydraulic actuators on top of which the wheels of the vehicle are placed. Movements of the actuators simulate the road surface and forces exerted by the road on the wheels. The movements of the system are tightly controlled by a digital test controller. During the research phase of a vehicle a 4-poster system is used to test newly desig… WebMoog 4-Poster Test Rigs, typically available in a 4 post as well as custom configurations, simulate vertical acceleration or displacement inputs of the wheel from data collected on the proving ground road, the system is …

WebMar 16, 2024 · Abstract In this paper, a new control method is presented for the 4-poster test systems. The primary aim of the paper is to improve the convergence speed and decrease the error rate for model-based iterative learning control (ILC), a widely used method as a tracking control. WebTo this end, a multiple-body simulation model of a vehicle in the GT3 racing class was developed for the 4-poster vehicle test stand; this combines the kinematics of the double wishbone axle, steering, stabilizers and body, while taking the payload and engine model into account. In addition, the hard points on the chassis of a real vehicle were ...
