AI Technical Summary

Technical Problem

Traditional aircraft side stick electrical performance testing is inefficient and inaccurate. Manual operation makes it difficult to accurately and repeatedly locate each specific angle point that needs to be measured, resulting in poor consistency of test results and high labor intensity.

Method used

Design an aircraft side stick test bench that utilizes an eccentric shaft linkage mechanism and a servo stepper motor to simulate the push-pull operation of the control stick through mechanical transmission. Combined with a programmable DC power supply and a digital multimeter, it realizes automated testing of the side stick sensor assembly.

Benefits of technology

It improves the accuracy and efficiency of testing, eliminates errors introduced by manual operation, and achieves efficient and accurate measurement of electrical parameters.
