Study On The Optimization Of Vehicle Handling And Stability Front Suspension Based On ADAMS

The pickup car in China belongs to niche models. But the advantage of a pickup truck is the truck and car. Suitable for our country’s villages and towns to use. Pickup truck with the opening of China’s rural and township markets will be rapid development. Because a pickup model is updating, the original target vehicle handling stability problems, this paper aimed at the stability of the high speed of the pickup truck, the impact factor analysis and optimization design.In order to establish the most accurate model to reflect the true performance of vehicles. In this paper, the vehicle’s front and rear suspension models are established according to the real size of the target vehicle in ADAMS. A whole vehicle model based on the idea of ADAMS system modeling. ADAMS vehicle model simulation test and comparison of the target vehicle handling stability test to verify the accuracy of the vehicle model. In the premise of ensuring the high accuracy of the use of ADAMS software for the simulation of the front suspension, to find the main factors affecting the stability of the control optimization.Firstly, the suspension model of the target vehicle is built. The front suspension is the double cross arm independent suspension, the rear suspension is the leaf spring suspension, here the author carries on the verification to the leaf spring suspension rigidity, ensures the rear suspension meets the request of the simulation precision.Secondly, based on the idea of system modeling, using a communication device in the steering system, engine, tires, suspension subsystem established vehicle model. And verify the simulation accuracy of vehicle model.Finally, based on the vehicle handling and stability problems, the front suspension positioning parameters simulation for vehicle high speed straight line travel stability becomes the reason of poor, and for the cause of multi-objective optimization, achieve the optimized results, finally verify the optimization results of theory, optimization is effective, simulation and optimization to achieve the goal.In vehicle design and optimization, the use of computer technology is the trend of future development, that is to improve the efficiency of the work, but also save a lot of manpower and material resources and time costs.
