| Abstract |
Vehicles are widely used in various industries and have benefited every household, and
ride comfort and safety are widely concerned by its customers simultaneously. Suspension
system as one of the modern automobile assembly, has a great impact on the vehicle's riding
comfort, handling stability, trafficability and other properties, so the performance of the
suspension system has always been one of the great concerns to vehicle designers, researchers.
In this Thesis:
1/4 vehicle suspension system was taken as the research object.
The dynamic model of the suspension system and the simulation model of the
suspension system are established.
Based on the main control objective of vehicle riding comfort, bodywork vertical
acceleration, suspension limit stroke and wheel dynamic loads are used as specific evaluation
indicators.
Comparative time domain analysis between active suspension and passive suspension,
between linear suspension and nonlinear suspension under different road surface excitation
were carried out using the theories of vehicle dynamics, modern control theory & approaches
and applications of Scilab simulation.
Controllers that meet design requirements was designed to effectively reduce vibration of
suspension under different road surface excitation signals.
The time sequence of this thesis to realize vehicle suspension system is to raise, analyze,
and solve issues. simultaneously 75 diagrams, 11 tables, 85 equations ,4 appendixes and 34
references was provided |
