Improvement of inverted pendulum test bench for inertial parameters measurement based on virtual prototype

A new measurement flow and data processing method for inertial parameters by using inverted pendulum test bench was proposed, which could efficiently identify the center of mass and inertial matrix of tested object. By utilizing ADAMS, the virtual prototype of inverted pendulum test bench for inertial parameters measurement was established and simulation was done. The results showed that the accuracy could be obviously improved by decreasing the shaft offset and the moment of inertia of the test bench. Furthermore, a non-bias axis inertial pendulum test bench was designed. Finally, the inertia parameters of a vehicle powertrain including mass center and inertia matrix were identified. The system can provide conditions to obtain the inertial parameters of complex components efficiently and accurately.
