摘要
为确认某型号的电动汽车副水箱的性能能否满足不同温度下的相关要求,利用Hypermesh对其三维模型进行网格划分建立有限元模型,用Abaqus进行热力耦合问题的求解和后处理,结果表明水箱可以承受分析条件下的温度和压力。设计了一项实验对分析结果进行验证,实验采用NI的数据采集设备和中航电测的应变片,在水箱表面选取了8个测点,每个测点分为X、Y两个方向,得到不同温度和压力下的应变曲线,水箱性能在实验中得到了验证。最后对仿真数据和实验数据在所选测点位置进行对比,在全部条件下的应变最大差值为571微应变,证明了有限元模型的有效性。
In order to confirm whether the performance of a certain type of electric vehicle auxiliary water tank can meet the relevant requirements at different temperatures,Hypermesh was used to mesh its three-dimensional model to establish a finite element model,and Abaqus was used to solve the thermodynamic coupling problem and post-processing.The results show that the water tank can withstand the temperature and pressure under the analysis conditions.An experiment was designed to verify the analysis results.In the experiment,NI data acquisition equipments and the strain gauges of AVIC ZEMIC were used.Eight measuring points were selected on the surface of the water tank,and each measuring point was divided into two directions,X and Y,to obtain the strain curves under different temperatures and pressures.The performance of the water tank was verified in the experiment.Finally,the simulation data and experimental data were compared at the selected measuring points,and the maximum strain difference under all conditions was 571 microstrain,which proved the validity of the finite element model.
