About Virtual CRASH

 

Virtual CRASH is a multi-purpose software application primarily used for accident reconstruction analyses. With Virtual CRASH you can simulate motor vehicle accidents, as well as pedestrian impacts, in full 3D. You can also draw scale diagrams, build and manipulate 3D models and terrain environments, and create stunning and incredibly lifelike HD animations. Virtual CRASH is used by professionals in academics, engineering, law enforcement, and the auto and insurance industries.

Our History


Our History


History of Virtual CRASH

 

The Virtual CRASH project began over 12 years ago in Europe by a collaboration of engineers and computer scientists dedicated to creating faster and smarter tools for accident reconstructionists. Since its start with Virtual CRASH 1.0, the Virtual CRASH project and its family of products have steadily increased in both functionality and popularity in the accident reconstruction community. It is widely used in motor vehicle accident research as well as by law enforcement, primarily in Europe, but has been steadily gaining in popularity with North American since being adopted by our first American accident reconstructionists over 10 years ago. Virtual CRASH software products are incredibly powerful and flexible tools which should be included in every reconstructionist's arsenal! Virtual CRASH software is used by academic institutions like Stanford University, large forensic engineering firms, as well as tech industry leaders like Uber. In 2017, we are proud to be releasing Virtual CRASH 4, which will add another level of functionality and power to the Virtual CRASH software platform with point cloud importing, the Easy Surface Builder, Google Earth, and more!

FREQUENTLY ASKED QUESTIONS

 

Here we present a video addressing frequently asked questions regarding Virtual CRASH 3.0. Note, many of the same answers apply to Virtual CRASH 2.2. A list of FAQs can also be found below.

  • Question: What collision model does Virtual CRASH use?
    • Virtual CRASH uses the Kudlich-Slibar rigid body impulse model. Virtual CRASH also has a simple rigid body dynamics collision model available. Deformation of the vehicle shells can be enabled, but note this is not a SMAC-based model.  
  • Question: What numerical integration methods are being used by the simulator?
    • Virtual CRASH has two numerical integration options available: (1) a fast sequential integration (iterative error correction) which uses a mixed Euler and Runge Kutta method, and (2) full integration which uses a complex NxN matrix with a mixed Euler and Runge Kutta method.
  • Question: Is it possible to change vehicle properties?
    • Yes. Vehicle properties can be changed using the control panel in the left column.
  • Question: Is the dummy model poseable? Does it have joint stiffness properties or is it just a rag doll?
    • Yes, the human model is poseable. All of the human model’s properties can be changed using the control panel in the left column. You can also pose the model interactively using the joint control grips.  
  • Question: Is it possible to modify the coefficient-of-friction between the roadway and vehicle or roadway and human model? Can the user input various “friction zones” across the scene?
    • Yes. In Virtual CRASH the user has complete control over the coefficients-of-friction between all objects that can interact. The user can input as many “friction zones” as needed using the various shape drawing tools.
  • Question: Has Virtual CRASH been validated?
    • Yes. The Virtual CRASH physics model has been the subject of many studies. Virtual CRASH performance has been compared against standard references such as RICSAC and JARI, as well as other staged experiments, and has been found to reproduce experimental results to excellent agreement. Please find more information on articles and validation studies on our website.   
  • Question: Virtual CRASH looks amazing! Why haven’t I heard of Virtual CRASH before?
    • Since Virtual CRASH’s start over 12 years ago, we have primarily focused on our European marketing efforts; indeed, most of our users are European law enforcement agencies and private consultants. We have only just recently started a concentrated effort to bring awareness of Virtual CRASH brand products to North America.
