实时仿真器

车辆的行驶和处理的准确实时模拟

Modelon的VDL.RealTime是Modelon的车辆动力学库(VDL)的扩展,提供了精确的高保真车辆模型的实时响应。工程师可以使用Dymola和VDL.RealTime开发实时运行的复杂而精确的模型。


在该解决方案的开发中,关键驱动力是需要更准确地预测底盘行为及其对车辆动力学的影响,特别是处理悬架的多体表达。这个以赛车运动开始和最新的技术改进为开端的需求已经转移到一般汽车行业。


使用VDL.RealTime,可以在驱动模拟器中部署超过150个自由度的车辆模型。悬架被详细建模,包括单个衬套和其他可变形部件。相应地,可以实时地执行包含多个物理域的其他子系统的准确模型,例如减震器,制动器和转向。


相同的高保真车辆模型可以在整个设计和验证过程中应用,包括用于离线和实时应用。使用相同的模型确保一致性和协作性 - 更快地提供更准确可靠的答案。


优点

使用准确的高保真模型:

  • 您可以在设计过程中进行更多更早的评估
  • 设计迭代更快,因为可以即时评估变化,而不需要中间模型简化或参数识别步骤
  • 您可以避免在精度和性能之间进行折衷

有一个模型和一类数据:

  • 您能确保工程工作的一致性,显著地减少维护工作

 

 

     


In the ultra-competitive world of motorsports, development time is almost as important as the speed at which a car navigates the track during a race.

Before design even starts, Dallara uses a real-time simulator to evaluate kinematics, steering geometry, aerodynamics, packaging, cooling, engine performance, monocoque stiffness and minor installation details.

Dymola and the Vehicle Dynamics Library were key drivers in developing the simulator. They enabled designers to quickly build models of every part of the racecar and share them among everyone involved in the development process, including vehicle dynamicists, aerodynamics engineers, designers, structural engineers and engine manufacturers.

Real-time simulation is being proven where the rubber meets the track: Dallara reports that its approach cut development time of the Nippon Super Formula car by more than half, and the physical car's performance and track feel are remarkably close to those of the virtual car developed on the simulator.

Their decision was based on:

  • The performance and accuracy of the vehicle model
  • The open and flexible environment that allows for multi-domain simulation
  • The ability to deploy the models universally across their organization
  • Modelon’s engineering expertise and reputation as a world leader in real-time vehicle modeling
