Abstract：

For the structural characteristics and the problem of deep drawing thinning for aero-engine fairing screen parts, the high temperature formability experiment of TC1 titanium alloy was carried out, the expanded blank of TC1 titanium alloy TC1 part was calculated,and the hot deep drawing process was simulated based on finite element simulation software PAMSTAMP. Then, the optimized simulation results were used for actual production. The research results show that the finite element simulation software PAMSTAMP can effectively predict the deep drawing defects of part, optimize the initial blank of sheet metal and the process route of deep drawing, save the trial production cost. Under the conditions of the blank holder force of 30 kN, the deep drawing speed of 3000 mm·s-1 and the friction coefficient of 0.12, the fairing screen parts with thinning size meeting the requirements can be obtained by adopting the optimized process scheme that the blank is thermoformed three times.
