摘　　要：以鲫(Carassius auratus)、草鱼(Ctenopharyngodon idellus)、鳊(Parabramis pekinensis)、黄颡鱼(Pelteobagrus fulvidraco)为试验材料,通过不同路况及车况的运输试验,研究车载活鱼运输过程中鱼体受力情况。试验测得车载活鱼直线行驶、过减速带及转弯运输的力值曲线,对力值曲线进行平滑滤波处理及提取力学特征值,并对车载活鱼运输的力学特征值进行显著性分析。结果表明:鱼的种类、车速、加速度对部分力学特征值的影响有显著差异,在3种行驶状态中转弯行驶对制动最大力值影响最大。Crucian carp,grass carp,bream and yellow catfish were used to investigate the force conditions for live fish under the process of transportation and obtain force curve of transportation for live fish through testing conditions of different road and vehicle including straight line driving,over deceleration belt and uniform circular motion.The force value curve was filtered and the values of mechanical characteristics were extracted and analyzed.The results showed that there was a significant difference of affecting values of partial mechanical characteristics under the different kinds of fish and speed of vehicles and speed of acceleration.Under conditions of the three different driving,uniform circular motion had the greatest impact on the maximum force.It will provide a foundation for studying stress mechanism of live fish carried by vehicles under conditions of different transportation.
