摘　　要：为研究装甲车辆在爆炸载荷下的动态响应,用AUTODYN软件对4340钢和橡胶构成的装甲车辆模型进行了三维模拟。计算了8701炸药不同装药量下的爆炸过程。得到了侧钢板上3个观测点的响应参数:超压、位移、加速度。分析了各观测点的动态响应规律。结果表明,离爆源位置越近或装药量越大,车辆的响应时间越早、节点振荡越激烈、振荡幅值越大、持续时间越短。To study the dynamic responses of armored vehicle to explosive loading, three-dimensional simulation of an armored vehicle model composed of 4340 steel and rubber was performed by an AUTODYN software. The explosion process of 8701 explosive with different charge mass condition was calculated. The response parameters of three observation points on the side of steel plate such as overpressure,displacement and acceleration were obtained. The regularity of dynamic response for the observa- tion points was analyzed. Results show that the closer from the explosion source location or the greater the loading charge, the earlier the response time of the vehicles, the more intense the node oscillation, the larger the oscillation amplitude and the shorter the duration.
