Direct current linear actuator using in the active suspension system of automobile

The active suspension system passes the action power produced by the actuator to improve performance and safety of vehicle. For the current prevalence of actuator in the active suspension there are many shortcomings, such as slow response, more energy consumption, low efficiency of storage energy, bad reliability, making the suspension frame more complex. A novel active suspension with energy by DC linear actuator is presented, and the structure principle of this active suspension and design scheme of this DC linear actuator are stated, and proposed DC linear actuator in the active suspension of automobile control system.

Electromagnetic Active Vehicle Suspension System

A new type of electromagnetic linear actuator for vehicle active suspension is designed. Combined with the finite element analysis tool, the effect of actuator structure parameters and power parameters on actuator thrust response is studied. Based on the simulation results, a prototype of electromagnetic linear actuator is developed. By comparison of the finite element simulation results and the experimental data, it shows the correctness of the finite element model and actuator design.

Research of Interactive Mode Based on the Multi-Side Collaboration

The value of instant message in computer-supported cooperative work is presented, and the disadvantage of instant message is analyzed when using the client/server, peer-to-peer or hybrid mode. The IMR (independent meeting room) mode is brought forward. This model divides into three levels, which are CSCW center, IMR and collaborative partner. The exchange and the data transmission between the partners are accomplished with the non-central P2P technology. Intelligent route arithmetic based on the dynamical transmission efficiency is provided. Each node can acquire the resource from the other nodes which can be used, and combine these nodes and which make these nodes take part in the flow distribution, path choice etc., and assume the minimum delay time. The independent meeting-room mode in this paper covers the shortage of the existing IM, which improved the communication ability by fully using the resource of the client, and it is the ideal communication method for multi-side collaborative working.
