Description

Technical Field

[0001] The utility model relates to the technical field of automobile vibration testing, and more specifically, to an automobile vibration testing device. Background Art

[0002] As society evolves, modern automobile design pursues lightweighting, safety, and comfort. When a car travels over bumpy and potholed roads, its operating conditions change accordingly, with various vehicle components experiencing varying states. To test a car's performance under varying road conditions (such as fatigue durability, shock absorption, and noise performance), it is necessary to conduct tests under various operating conditions. Common automotive tests include actual vehicle road tests and laboratory bench simulation tests.

[0003] The existing patent number is CN108195599A. A vehicle vibration test device primarily consists of an environmental chamber, a mounting floor, a Stewart parallel mechanism, a control system, and a hydraulic drive system. The mounting floor and Stewart parallel mechanism are both located within the environmental chamber. Four sets of Stewart parallel mechanisms are symmetrically mounted on the mounting floor, and the vehicle to be tested is placed atop these four sets of Stewart parallel mechanisms. This device can simulate the collision relationship between the entire vehicle and the road surface, thereby more realistically reflecting the vehicle's vibration state as it fluctuates with the road surface. Combined with the temperature, humidity, and lighting conditions provided by the environmental chamber, the device can perform vibration testing, noise testing, fatigue endurance testing, and other related tests on the entire vehicle. This vehicle vibration test device can reduce vehicle testing time and improve test results. However, the device requires complex transportation before and after vehicle testing, and this transportation process is complex and inefficient, resulting in a problem in which processing and testing efficiency cannot be improved.
