For accurately and efficiently simulating the rotary inertia of automotive transmission in actual working condition

realizing the detection for durability of various automotive transmission

the inertia simulation system of endurance test-bed for transmission is designed based inertia simulation method

which has mixed the machinery and electricity.According to the hybrid inertia simulation method

the design principle of the flywheel groups is determined

and kinetic energy compensation system is established.The electrical machinery is regulated by the rotational speed control method so that the kinetic energy for the flywheels is compensated and the efferent inertia of system is regulated

the simulation context of the test-bed is analyzed.Finally

taking the test-bed with the basal inertia of 10kg·m2 as example

when its designed deceleration is 0.6g

the simulated inertia scope of 0

1

95kg·m2 is realized by regula

ting flywheel groups and the domination of electrical machinery

the inertia requirements of light-duty vehicle

mid-size vehicle

and heavy-duty vehicle is met

and its possesses high analog accuracy and low experimentation cost

so that will be more useful in actual application.
