The invention relates to the technical field of aviation assembly, in particular to a method for calculating the gasket adjustment amount in the coaxiality adjustment process of a helicopter tail transmission shaft, and the method comprises the steps: constructing a target key point and a target virtual camera of the helicopter tail transmission shaft, so as to determine a first coaxiality error representation vector of the helicopter tail transmission shaft; obtaining target measurement data of the helicopter tail transmission shaft, and equivalently mapping the target measurement data to the first coaxiality error representation vector to obtain a second coaxiality error representation vector meeting a preset format; and inputting the second coaxiality error representation vector into a pre-calibrated mathematical solution model to output the adjustment amount of each gasket of the helicopter tail transmission shaft. Therefore, the problems that in the prior art, only two sets of single circular targets are measured, the coaxiality of the helicopter tail transmission shaft cannot be effectively observed, the adjustment amount of the installation gasket is estimated only according to manual experience, the labor cost is increased, and the accuracy of the adjustment amount of the gasket is reduced are solved.

    本申请涉及航空装配技术领域,特别涉及一种直升机尾传动轴同轴度调整过程中垫片调整量的计算方法,方法包括:构建直升机尾传动轴的目标关键点和目标虚拟相机,以确定直升机尾传动轴的第一同轴度误差表征向量;获取直升机尾传动轴的目标测量数据,并将目标测量数据等效映射至第一同轴度误差表征向量中,以得到满足预设格式的第二同轴度误差表征向量;将第二同轴度误差表征向量输入至预先标定的数学解算模型中,以输出直升机尾传动轴的各个垫片的调整量。由此,解决了相关技术中仅对两组单一圆靶标进行测量,无法有效观测直升机尾传动轴同轴度,并且仅依据人工经验对安装垫片的调整量进行估计,增加人工成本,降低垫片调整量的准确性的问题。
