The invention provides a
spacecraft environment test sensor clipping method, which comprises the following steps of: pasting sensors inside and outside a cabin of a preorder test
spacecraft in a
spacecraft to be tested, and executing an environment test to obtain response data; according to the sensor pasting positions, spacecraft measuring point classification is carried out;
cutting off corresponding in-cabin test points and out-cabin necessary test points in a subsequent test spacecraft; a KMeans clustering model with the preset number of reserved measuring points as the classification number is established, and the corresponding outboard optional measuring points in the spacecraft are
cut in the mode that one measuring point is reserved for each category through the KMeans clustering model; establishing a spacecraft response prediction model based on
machine learning, and taking the response data in the preorder test spacecraft as a
test set and a
training set; and the average error and the
maximum error of response prediction of the measurement points output in the
test set are adopted as model evaluation parameters, and the number of the preset reserved measurement points is adjusted to determine the reserved measurement points of the subsequent test spacecraft. Therefore, the response of each part of the spacecraft can be accurately obtained, the spacecraft environment test can be safely and quickly carried out, and the
thermal control measures on the outer surface of the spacecraft are protected.
