Military Off-road Vehicle Ride Comfort Simulation And Optimization

This paper uses military off-road vehicle ride comfort simulation and optimization, introduces virtual prototyping technology in military research and development, and from the following several aspects:the military cross country vehicle ride comfort research process:1The discussion of the domestic military off-road vehicle ride comfort and impact of research significance of the main factors ride, a brief study of the situation at home and abroad.2Discusses the human response to vibration sense of boundaries and three different military off-road vehicle ride comfort evaluation methods.3Discusses the military off-road vehicles from the ride comfort considerations, independent suspension structure should be significantly better than non-independent suspension.4Describes the double-wishbone suspension system design and optimization process, emphasizing the design of suspension elastic element determines the vehicle’s ride comfort, and guidance agencies will determine the wheel alignment parameters, suspension kinematics can meet such requirements.5. A brief introduction to the physical prototype test ride the two test methods:Methods and road test bench method, and by the idea of bench introduced a simplified method of military off-road vehicle "suspension-tires-road," composed of vibration system. According to the system composed of the basic elements, through the ADAMS/View software established the virtual prototype model of vibration system.6. Damper on two random road ride comfort simulation, based on the simulation results to optimize the combination, to determine the before and after the suspension of the final selection, and in accordance with the optimized pulse shock absorber for road simulation, observe the simulation results.Military off-road vehicle development work is a systematic project, need to go through during the research project, program verification, engineering, prototype evaluation, prototype testing and design stereotypes shape the six work areas. Every aspect of the problem, may lead to the front part to start. If the ability to link up potential problems before they occur can be resolved, take precautions, you can save the product development cycle and development cost, faster service in the army needs to accelerate the development process of domestic military vehicles.
