Abstract

The invention provides a cab suspension system vibration fatigue test platform which comprises a cab, a servo linear actuator, a hydraulic control system, a servo amplifier, a software evaluation and analysis system, and a cab suspension system. The servo linear actuator comprises a hydraulic servo valve, a hydraulic cylinder and a displacement sensor. The hydraulic servo valve is driven by the servo amplifier. The hydraulic cylinder is driven by the hydraulic servo valve to move up and down, the servo linear actuator is pushed to move, and the cab is driven to move by the cab suspension system. At the same time, the movement displacement and speed of the hydraulic cylinder are transmitted to the software evaluation and analysis system through the displacement sensor. Therefore, according to the test platform, the purpose of detecting the qualification of the cab suspension system performance and cab other part performance in the test platform without a running test can be achieved, and the test cost is greatly reduced.

Description

technical field [0001] The invention relates to performance test equipment for a cab suspension system of medium and heavy trucks, in particular to a cab suspension system vibration fatigue test platform capable of detecting the performance of the cab suspension system without a road test. Background technique [0002] Cab suspension refers to the use of spring damping elements to form a suspension system to suspend the cab on the frame. At present, the cab suspension system mainly includes two types of full-floating cab and semi-floating cab according to the structural form. The full-floating cab, that is, the cab is composed of four sets of elastic elements, front, rear, left, and right. The suspension system suspends the cab on the frame. Compared with the full floating cab, the two supporting points at the front of the cab are connected to the frame by hinges, and the rear suspension structure is also composed of springs and damping elements. The rear suspension is conn...
