    IS SIMPLE CAR CRASH SIMULATION IS POSSIBLE OR NOT

    Dan Singh

      Actually i am working on a project on car crash test and i just want to know whether it is possible or not.

      i just want to know the effect of collision on vehicle chasis

      if it is possible, help me

      thanks in advance for help

      welcome to any tips

          Hi Dan,

           

                         Can you specify you want to carry crash test on whole car model or just on chasis

          B'coz

          When considering only chasis the loads applied during crash point are to be calculated from the all parts of car

          and on contradictory when you perform a car model for crash the loads are transfered remotely with each part connecting to chasis

          also the specimen on which the car is crashed has its unique effect as if you try to crash car on beam instead of wall or on rod they will have respective displacements and fatigue results

          even the direction and degree of freedom and speed(Velocity/Acceleration) is also supposed to take in account.

          combine effect of motion study and simulation is needed

           

          Hope this will help you to go with clear idea for simulating car crash  let me know if it works

            crash simulation is not possible with SolidWorks according to my knowledge

              Dan,

               

              Vechile (and most any) crash scenario is extremely difficult to simulate, given all the deformations, collision/elastic propteries, and loads involved.  You can do a drop-test on the frame in SW, but that's about as far as you could go without spending a month setting up the model and another month letting it solve non-linearly!  Even then it takes some serious software to allow part breakage (self-shear and detachment from assembly) if you want to get detailed.  For just the chassis/frame though (no suspension/body/components, you could set up a drop test and just calculate you angle and speed of the impact with decent results I would think.

                LS-DYNA is well regarded for its crash simulation. This type of thing requires sophisticated knowlege of finite element analysis--there is no user-friendly way to do what you are asking. Solidworks Simulation is geared to the designer, not high end analysis.

                  I tried various method but unable to get the desired result.

                  Mike i am agree with you.

                  thanks to all
