Abstract

The invention relates to the technical field of mechanical testing equipment, in particular to a fatigue durability testing device, and solves the problem that an automobile transverse stabilizer bar product is subjected to fatigue durability test under various working conditions. The fatigue durability testing device comprises a power device. A torsion driving cylinder is arranged in the power device. An output end of the torsion driving cylinder is provided with a torsion driving swing arm. The torsion driving swing arm is of a strip bar structure, is vertical to the axial center line of the torsion driving cylinder and is eccentrically arranged. The transverse stabilizer bar is provided with two pieces in the horizontal direction. The torsion driving cylinder can load a sinusoidal waveform, triangular wave, random wave or path spectrum signal under the control of a computer. By using the fatigue durability testing device, the test is stable and the efficiency is high. Various actual using working conditions are simulated. The comprehensive cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of mechanical test equipment, in particular to a fatigue durability test device for a lateral stabilizer bar. Background technique [0002] The stabilizer bar is an auxiliary elastic element in the car suspension. Its function is to prevent the body from excessive lateral roll when turning, prevent the car from laterally tipping and improve ride comfort. ??In the actual working state, the stabilizer bar is often subjected to different torsion forces, and fatigue damage will occur in some parts as the number of stresses increases. Therefore, in the manufacturing process of the stabilizer bar, it is necessary to design a test device capable of simulating various torsion forces and exerting them on the stabilizer bar. The structure of the fatigue test device for industrial products is various, and it is generally designed according to the characteristics of the product. For example, the patent publication nu...
