The invention discloses a test field association method for an automobile structure endurance program. The method comprises the following steps: firstly, carrying out target test field working condition analysis and association channel determination, then carrying out association test field and target test field road spectrum acquisition, load spectrum analysis and relative damage calculation, then constructing an association model, carrying out optimization solution, carrying out optimization solution adjustment according to association result verification, and finally generating a test fieldspecification. By reasonably selecting an association channel and setting optimization solution constraints, test field association with relatively high practicability is realized, and technical support is provided for durability verification of a whole vehicle test field. 一种汽车结构耐久程序的试验场关联方法，首先进行目标试验场工况分析、关联通道确定，然后进行关联试验场和目标试验场路谱采集、载荷谱分析、相对损伤计算，然后构建关联模型，进行优化求解，并根据关联结果验证进行优化求解调整，最后生成试验场规范。通过合理选择关联通道，设置优化求解约束，实现实用性较强的试验场关联
