Foreword The complex products remote collaborative design based on internet has been developed into information integration and control which is supporting concurrent engineering, and virtual enterprise design mode of different collaborative technology which is supporting CSCW.
For this reason, Linxuan Zhang presented the general structure of remote collaborative design facing ASP, discussing main key technology and its corresponding solution, including synchronization mechanism of multi-person remote collaborative design, high-efficient & low-load image compression and transmission technology, resource sharing conflict resolution technology based on correlative relationship[1].
Computer internet technology will bring another revolution in engineer design area.
The involved decision problems can be divided into three kinds: choosing design entity when organizing alliance, choosing different parties to carry out the task when allocating task, choosing suppliers when purchasing commodity or raw material.

Dynamic Simulation for Driver-Tricycle-Road System with Rigid-flexible Coupling Xiang Han1,2 1College of Mechatronic Engineering, Xuzhou Institute of Technology, XuZhou, 221008, China 2College of Mechatronic Engineering, China University of Mining and Technology, Xuzhou, 221006, China E-mail:xnghan@126.com Keywords: Tricycle; Rigid-flexible Coupling; Dynamics; Driver-tricycle-road System Abstract.
The Establishment of the Tricycle Rigid-flexible Coupling System Dynamics Model To establish the tricycle rigid-flexible coupling system dynamics model efficiently, the author first constituted its multi-rigid-body dynamics model, then replaced corresponding parts rigid model with flexibilities of frame and leaf spring which are key role to the tricycle system performance.
The leaf spring is a elastic component of the suspension of automobile, engineering and agriculture transportation vehicle, which is used to transfer lengthways and transverse force.
The essence of BEAM is to divide every leaf spring into several small pieces that are seen as rigid body, but every two pieces are connected with mass-less BEAM flexible beam whose stiffness and damping matrix are calculated automatically by Adams according to the cross section and material parameters of the leaf spring.
