Hydraulic simulation test bench for semi-vehicle active suspension system

Abstract

The invention discloses a hydraulic simulation test bed for a half-vehicle active suspension system. The hydraulic simulation test bed comprises a half-vehicle simulation rack, a half-vehicle guide frame, a front hydraulic system simulation excitation table and a rear hydraulic system simulation excitation table, the half-vehicle simulation rack is supported on the table surfaces of the front hydraulic system simulation excitation table and the rear hydraulic system simulation excitation table through front and rear wheels; the front hydraulic system simulation excitation table and the rear hydraulic system simulation excitation table are fixed on a bottom frame of the half-vehicle guide frame through excitation table fixing rods; the half-vehicle simulation rack is installed in the bearing assembly component of the half-vehicle guide frame through the two ends of the central shaft, and movement of the half-vehicle simulation rack in the vertical direction and the pitching direction is achieved.

Description

technical field [0001] The invention relates to a hydraulic simulation test bench for a semi-vehicle active suspension system, which belongs to the field of mechanical equipment. Background technique [0002] Under the general trend of the transformation of global commercial vehicles towards "electricity, light weight, and intelligence", as an important component of the chassis system, suspension technology has also shown clear development in terms of electronic control, light weight, and intelligence. context. Its development trend mainly focuses on the two aspects of suspension electronic control technology and material technology, among which the development trend of electronic control technology is reflected in the development of passive suspension technology to active suspension technology. [0003] Compared with traditional passive suspension and semi-active suspension, active suspension, as a new type of suspension system structure, has been placed high expectations ...

Problems solved by technology

However, this test platform can only verify the control effect of the proposed control method in the vertical direction of the active suspension system of the vehicle, while ignoring the pitching motion generated during the actual vehicle operation.
