Abstract:
The solid and finite element model of metal pushing type
continuously variable transmission are established at speed
ration of I=0.5 and I=2.0. In order to solve the problem of the
complicated of structure, the node-node rod discrete finite
element model is put forward and the whole system is simplified
and established. The natural frequency and mode shape of system
are solved by iterative Laneczos-reduce method for sensitivity
analysis in finite element model. The new method and the result
can be used to improve the smoothness of the variable
transmission system and to propose the theory for reducing noise
at operation.
Key words: Continuously
