摘要
根据GB15083-2006标准规定的汽车座椅强度试验时台车减速度波形要求,通过对台车和节制杆碰撞的受力分析,应用流体力学理论建立了节制杆截面形状设计与修正的数学模型,以模拟实车碰撞过程中汽车座椅变形情况。试验结果表明,所设计的节制杆式模拟汽车座椅强度试验装置,只需调整节制杆的工作行程和弹-塑性缓冲材料即可保证试验台车的碰撞减速度满足法规要求,为汽车座椅强度的设计评价提供了可靠的试验检测手段。
Based on GB15083-2006 requirements for waveform of the sled deceleration in the vehicle seat strength test and the force analysis of sled and control rod,the shape design and correction model of the control rod cross-section was built with hydrodynamics theory,to simulate the deformation of vehicle seat during impact process.The tests results indicate that the rod controlled simulation test device can meet the legal requirement for sled impact deceleration,if only to adjust the working stroke and elastic buffering material of control rod,which provides reliable test and inspection measures for the vehicle seat strength design evaluation.
