Abstract
In this paper, a simulation model of flexible virtual proving ground (VPG) for a car was created in view of the shortcomings of long test cycle and high cost of traditional enhancement test for suspension durability at car development stage, with a variety of durability enhanced roads in the Nong’an Proving Ground as inputs. It solved a string of key technological problems regarding VPG applications. In addition, the time-history dynamic stress response of a car suspension system was analyzed, compared with the real vehicle durability test results obtained under the same conditions. The results of the simulation test and the real test are basically identical in terms of the trend of time and frequency domains. Furthermore, it demonstrates the effectiveness of the simulated suspension system’s dynamic stress response for the flexible VPG technology, and realized the effective prediction for the suspension system durability in the development process.
