摘要
根据车身结构的力学特点,建立了车身实验模型并对车身进行了弯曲实验,掌握了该车身结构的静态特性;为进一步的灵敏度分析和结构动力学修改及优化设计奠定了基础。
The establishment principle of mode experiment model and establishment method of test system was illuminated through study to the vehicle body. And mode parameter identification was carried out to the data connected. Configuration static feature of this vehicle body was seized. The bending experiments of the body were carried out. This was very useful for the sensitivity analysis and structure dynamical updating.
