Abstract :
A kinematical equivalent mechanism names as 3-RUS+PU paralled mechanism is proposed according to the structure of helicopter non-rotating swashplate mechanism in hingless rotor with Bell-hiller stabilizer bar. Inverse solution is used to get the position analysis of this mechanism. By virtual mechanism method, influence coefficient matrices of this mechanism are given, and the correctness is validated by differential method. With considering the size and mass of mechanism, the atlas of acceleration performance indices and inertia force performance indices are got. From the atlas, the better size with better performance indices is chosen by using the trend between the value of performance indices and the size of mechanism.
