【Abstract】 Based on the mass-period method, a measuring device named double spring inversion pendulum was designed, which could measure the center of mass and moment of inertia of an engine. The measuring theory and demarcation method about parameters of the test rig were introduced. Aiming at the non-isochronism in the test, the reason inducing the phenomenon was analyzed by combining tests with the virtual prototyping technology and an effective solution was put forward. Finally, the parameters measure and results of one mini-car engine were introduced. The results showed that the measuring device is feasible.更多还原
