Variable-temperature variable-angle impact test control method

The invention discloses a variable-temperature variable-angle impact test control method. An impact test device for realizing the control method comprises a heating and heat preservation device, an automatic double door device, a test piece clamping and angle adjusting device and a sensing detection and control device. According to impact table air pressure control, an air pressure set value u0 is compared with a real-time measurement signal of a pressure sensor through a position type PID algorithm to obtain a deviation e, the deviation e is calculated to obtain a PWM signal duty ratio adjusting variable u, the PWM signal duty ratio adjusting variable u is converted into a control variable to adjust a high-pressure air source pressure adjusting valve, and the air pressure is stabilized at a preset value. The installation angle of the test piece can be accurately controlled through conversion of the step angle and the transmission ratio between each stage of gear and worm.
