Week 12 - Flex Bodies

a model is been designed for front end of the vehicle for SLA assembly    Results are as shown below  Displacement :  Strain gain :  stress Generated:   

Ans. Y displacment of the follower w.r.t. cam is shown as follow.  Case : 1  Curve to curve (CV-CV) joint.  Case: 2 3D contact between cam and follower 

  viewing the initial CSV file, we get to know that the truck lid hits the truck after 3.1 sec modifying the displacement values to zero after 3.1secupdated curve  importing the new curve values to motion. running the simulation 

Ans.1  an Inline joint will be used at joint C in order to avoide redundecncy in the system.  Ans: 2  Velocity at joint 2 W.r.t time  Ans.3  Applied a force of 1000KN at P0 Ans: 4  to constrain the motion of link 1 from 0-10rads. 

1. Simulating the Free fall of a body of mass 1kg and inertia 1kg/m2,  Resutls in.      2. The Free fall of an object is given as.  h = 1/2xgxt^2 g: Acceleration due to gravity  t: duration of falling object.  So from the above equation it's clear that a free falling object only depends…
