The invention discloses a stamping forming analysis method for a vehicle frame cross beam part. The stamping forming analysis method comprises the steps that S1, extracting an outer surface of a vehicle frame cross beam part S2, importing an outer surface file of the frame cross member part into stamping forming simulation software, and unfolding the outer surface of the frame cross member part toobtain the plate size of the frame cross member part; S3, performing process supplement on the frame cross member part to form a female die of the die, and exporting the female die as a female die file; S4, importing the sheet stock line file and the female die file into stamping forming simulation software, forming a male die of the die, controlling the gap between the female die and the male die within the range of 1.0-1.2 a,wherein a is the thickness of the sheet stock; S5, when the gap between the female die and the male die is smaller than or equal to a, finishing forming and S6, checking parameter data of the f
