In order to solve the problems of  low work efficiency and frequent accidents of production safety for small- and medium-sizefishing vessels, a five wheels-net hauler was developed. In order to confirm optimum working parameters and working performance of five wheels-net hauler, working principle and force load of friction hub wheel were introduced and analyzed  and the mathematical model was determined. The friction and frictional torque between the friction hub wheel and bush rope  were ascertained.  By applying variational design and solid modelling technology of Pro/E, the three-dimensional mode of five wheels-net hauler was established, which achieved the modelling and assembling of various components of entire hauler body. The rationality of mechanism design is verified by interference analysis. Then, the 3D model of the whole body was mapped into the ADAMS environment by using the software Mechanism/pro for dynamic simulation analysis.   Based on the analysis of speeds of different motors, friction coefficient and wrapping angle between friction hub wheel and bush rope, the optimal working parameters of the machine were determined: 110 r/min for motor speed, 25m/min for hauling speed, 0.4 for friction coefficient of friction hub wheel, less than 70° for the angle between bush rope and shipboard. All parameters meet the specification and stable performance. The best work parameter for the five wheels-net hauler is Using Adams/VibrationVibration module to analyze the vibration characteristic of five wheels-net hauler, the frequency range for strong vibration was 30~40Hz. These conclusions obtained has laid the foundations for improving working performances and parameters optimization of five wheels-net hauler.
