Abstract:

To solve the multi-rigid-body system dynamics modeling of complex, difficult issues such as computer simulations, R-W method were provided to establish multi-rigid-body system dynamics model. Through the establishment of dynamic model of bolting machine, the dynamic model formula is obtained, by solving the equation, body position is found. According to correlation of body position and simulation test, maximum error only is less than one percent, so it confirmed R-W method in multi-rigid-body system dynamics modeling accuracy, simplicity and advantages.

Key words: multi-rigid-body dynamics, dynamic model, R-W method
