Abstract: According to human dimensions of chinese male pilot and the chinese manhood anthropometric data, the rigid model for the pilot′s upper limbs was established. Referring to the requirement about cabin layout in GJB and flight quality criterion in HB, Two operation movements of the pilot, pulling and pushing stick, were simulated using SimMechannics which is a simulation module of Matlab. Analysis type is inverse dynamics. When work load and athletic rule of end effectors are given, the actual joints′ torques could be ciphered out by simulation, and then the three-dimensional comfortable manipulation area could be acquired according to given comfort criterion. The result suggests that workload isn′t changed, but the calculated area in the case of pushing stick is different from that of pulling stick. Therefore, there is a correlation between manipulation characters and the range of comfortable manipulation area. When dealing with pilots′ ergonomics evaluation or optimizing cockpit layout design, It is necessary to analyze matters with an eye to manipulation characters.
