Tyre Assembly Analysis

Recommended Posts

Hi Johnson,

 

   Kindly find the image sent to you in drop box

   Wheel with tyre assembly is given load at center by using rigid element

   Ground defined as shown in the image. Contact defined between tyre & Ground

   How this type of analysis can be done in optistructWHEEL_FLOOR_STATIC.thumb.jpg.2963901eca31b6c25f537cdec8eb1726.jpg

Hi Naveen,

What is the objective of the simulation, based on which methodology can be decided.

 

Based on above inputs, the force as function of time can be applied at tyre centre and transient run can be performed.

Hi Mr.Gopal,

 

   Thank you for the reply

   Can be done in transient. We are planning to do in optistruct.

   Steel property defined for wheel. Rubber property to be defined for tire

   What material card can be defined for rubber property in optistruct (Suggest us in material card and basic properties)

   Load is given using rigid element at disc centre

   Contact between ground and tyre defined(need clarification on defining contacts)

   Image attached for your reference

Hi Naveen,

 

You can run a non linear transient analysis and for rubber material please refer MATHE card on OptiStruct help. 

 

But in case you want to include monitored volume, it is better if you use RADIOSS.
