Abstract

The invention discloses three-directional dynamic performance test equipment for a vehicle suspension leaf spring, and the application thereof. The test equipment comprises a power source, a test bed and a software control system. The test bed comprises a base, four stand columns and a fixing plate. A steel plate spring suspension is inverted, coiled lugs at the two ends thereof are fixed on a plate spring bearer 1 and a plate spring bearer 2. The bottoms of the plate spring bearer 1 and the plate spring bearer 2 are matched with sliding rails on the base and fixed on the sliding rails through a guide rail locking device. An inverted simulated vehicle axle is fixed above the middle part of the steel plate spring suspension. The side surface of the steel plate spring suspension is horizontally provided with a longitudinal loading mechanism. The side surface of the simulated vehicle axle is horizontally provided with a transverse loading mechanism, and a vertical loading mechanism connected with the fixing plate is arranged above the simulated vehicle axle. The power source provides power, and controls the longitudinal loading mechanism, the transverse loading mechanism and the vertical loading mechanism to conduct the three-direction synchronous loading operation onto the steel plate spring suspension by adopting the static step-by-step loading method and the dynamic harmonic excitation method through the software control system.

Description

technical field [0001] The invention relates to the technical field of vehicle performance detection devices, in particular to a three-way dynamic performance test equipment for a vehicle suspension leaf spring and its application. Background technique [0002] As people's requirements for cars are getting higher and higher, while ensuring economy and power, cars are also required to have good driving comfort and handling stability. Leaf spring is the most widely used damping element in truck suspension, and it is also the guiding device of suspension. It can transmit various forces and moments, and is a key component that affects the wheel runout trajectory, vehicle ride comfort and handling stability. [0003] The leaf spring adopts a multi-leaf spring superimposed structure. Because of the complex stress and deformation conditions and the large number of leaf springs, it is very important to accurately obtain the stiffness and damping characteristics of the leaf spring f...
