In order to relieve the damage to the equipment and the attack to the electricity net

when the heavy-duty transport machine is starting suddenly

we initially designed the structure which is composed by the planetary gear and clutch installed which can turning the freedom from 2 to 1 step by step by controlling the increment of the fluid viscous force between clutch discs

so that the output axis will be loaded flexibly which the help of the tri-dimension flat-form UG

the digital prototyping of the flexible load-applying system is established

and with the help of the kinetic analysis module

the dynamic simulation and the finite element analysis of the soft starting system will be made

which can ensure the exact function of the physical prototyping.
