The embodiment of the invention discloses a multi-channel coordination control method for an airtight strength test of a large-volume airplane. The method comprises the steps: determining the gas flowstate of an inflation/deflation valve according to the inflation/deflation working principle of an inflation platform and the inflation/deflation process of an airtight cabin; according to the determined gas flow state, establishing a time mathematical model for inflation/deflation of the airtight cabin, and calculating the inflation time and deflation time of the airtight cabin, wherein the timemathematical model for inflation/deflation of the airtight cabin comprises a time mathematical model for inflation of the airtight cabin and a time mathematical model for deflation of the airtight cabin; according to the inflation time and the deflation time of the airtight cabin, determining the type and the number of the inflation tables and time setting of the load spectrum; and establishing avirtual control loop, and carrying out multi-channel coordination control on the airtight test strength test. According to the multi-channel coordination control method based on inflation/deflation time calculation, the test efficiency and the control precision are improved.

    本发明实施例公开了一种大容积飞机气密强度试验的多通道协调控制方法,包括:根据充气台的充/放气工作原理和气密舱的充/放气过程,确定充/放气阀的气体流动状态;根据已确定的气体流动状态,建立气密舱充/放气的时间数学模型,并计算气密舱的充气时间和放气时间,气密舱充/放气的时间数学模型包括气密舱充气的时间数学模型和气密舱放气的时间数学模型;根据气密舱的充气时间和放气时间,确定充气台的型号和数量,以及载荷谱的时间设置;建立虚拟控制回路,对气密试强度试验进行多通道协调控制。本发明实施例基于充/放气时间计算的多通道协调控制方法,提高了试验效率和控制精度。
