The transmission is an important part of the vehicle.Its lightweight design is already an important component in the commercial vehicle lightweight design.In the development process of QX-25 Llight commercial aluminum-housing transmission

the static analysis calculations is designed to meet the requirements of the situation

but road test appeared broken clutch housing failure

and therefore must be kinetic analysis of the transmission.The modal characteristics of QX-25 L commercial vehicle transmissions is studied

by using the method of combining simulation and experimental

the modal characteristics of the transmission is determined

the basic data support for vehicle dynamics testing and calculation analysis is provided.
