基于整车路面谱的副车架开裂台架试验及仿真OACSTPCD
Sub-frame Crack Rig Testing and Simulation Analysis Based on Full-vehicle Rough Road Spectrum
针对前悬架稳定杆与副车架连接处在整车试验场耐久测试过程中出现的疲劳破坏问题,通过对稳定杆进行贴片标定,获得了试验场环境下稳定杆的连杆力和稳定杆扭转相对位移的强化耐久路谱,设计搭建了稳定杆副车架系统的物理台架,并按照耐久性规范进行了台架试验.试验结果表明:该台架试验装置能良好地再现整车耐久路试下的断裂位置,疲劳寿命相对于整车耐久路试的疲劳寿命偏差仅为2.5％.在此基础上,建立了稳定杆与副车架多体的仿真模型,设定了与系统试验台架相同的约束边界,通过虚…查看全部>>
The study was conducted to examine the durability issue occurred in front stabilizer bar bracket connect-ed to sub-frame in full vehicle testing.Firstly,stabilizer bar system was plastered with strain gauges and calibrated,and drop link force and stabilizer bar twist displacement acquired on proving ground,sub-frame with stabilizer bar system physical test rig was designed and built,and rig tests in accordance with durability specifications were con-ducted.T…查看全部>>
