汽车产品的耐久性是影响其竞争力的重要因素,同时其开发周期与成本迫切需要在产品概念设计阶段对其耐久性进行控制。针对轿车开发过程中传统悬架耐久性道路强化试验周期长费用高的缺点,以农安试车场各种耐久性强化路面为输入条件,应用虚拟试车场技术(Virtualprovingground,VPG)建立某轿车整车柔性虚拟试车场仿真模型,解决虚拟试车场技术运用中的轮胎模型、橡胶衬套刚度、路面模型和整车模型计算效率等关键技术,分析轿车悬架系统时间历程动应力响应,并与相同工况下的实车耐久性试验结果进行对比,仿真结果与测试结果时域和频域趋势基本一致,验证柔性虚拟试车场技术仿真的悬架系统动应力响应的有效性。在此基础上,实现开发过程中悬架系统耐久性的有效预报。 The durability of automotive products is an important factor to affect their competitiveness;meanwhile,due to their long development cycle and huge costs,the durability control in their conceptual design stage is in great need.Virtual proving ground to predict the durability has been used to performance of a passenger car suspension.A simulation model of flexible virtual proving ground(VPG) for a passenger car has been created,with a variety of durability enhancement roads in the Nong'an Proving Ground as inputs.A string of key technological problems(tire model,stiffness of bushing and roads model) regarding VPG applications has been solved.In addition,the time-history dynamic stress response of a car suspension system has been analyzed,and compared it with the real passenger car durability test results obtained under the same conditions.The results of the simulation and the test are basically identical in terms of the trend of time and frequency domains.Furthermore,the effectiveness of the flexible VPG technology for the simulated suspension system's dynamic stress response has been demonstrated,and the effective prediction for the suspension system durability in the development process has been realized.
