Based on human arm and serial robot theory, a model is established to get the acceleration and velocity performance index of the humanoid-arm mechanism. Using these indices, the dynamic performance of the mechanism is analyzed and the atlas of the indices contoured by Matlab is given. Through analyzing the results of simulating atlas, the optimum size of the humanoid-arm is derived. Using a group...
Acceleration global performance index based on Jacobian and Hessian matrices for one-loop planar mechanism is proposed. Using acceleration global performance index, acceleration performance of crank rocker mechanism is analyzed and atlas of dynamics performance indices is given. By using the result of atlas, mechanism with better acceleration is found. At last, the crank rocker mechanism is simulated...
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...
