●Measuring System for Principal Moments
of Inertial of Engine
This measuring system can precisely measure the values
of principal moments of inertia of the transmission engine
and the rigid characteristics such as the direction, weight,
position of the center of gravity, and other parameters of
the principal axes of inertia in a short time. This system
can decide the ideal arrangement and characteristics of
the engine mount by using these highprecision measured
values for analyzing the engine vibrations as a system
indispensable for the vibrationproof design of the engine.
