Problems solved by technology

[0002] The traditional technology does not have a static rollover stability test bench suitable for non-road vehicles, but a test bench for testing the static rollover performance of road vehicles such as automobiles. Most of the test benches can only perform unilateral rollover. The preparation period is long, the operation is complicated, the workload is large, the test efficiency is low, and the maximum rollover stability angle of the vehicle in the longitudinal and lateral directions cannot be detected at the same time. The lifting power of the tilting mechanism of the test bench adopts a hydraulic system, which is difficult to meet the standard NY / T1929-2010 The stability and lifting speed test requirements in the test make the test bench structure and measurement and control technology complex, the cost is high, the measurement accuracy is not easy to guarantee, and it is difficult to apply to the tractor static rollover stability test of non-road vehicles
