Multiple LoadCases with a factor for consecutive Angle - Reg

Hallo,

 

I am having a model of bicycle pedal crank in which I want to apply loads on the pedal ( on the created node). If we take the pedal goes 360degree I want to split the 360 into some lets take 18 steps so I have to create 20 load cases. I considered when the pedal is at top as Top dead center ( TDC) and when it is at bottom Bottom dead center (BDC).  The load which i apply on the tdc is high and when it goes bdc it gets reduce and again to complete one cycle the load goes load just like the real case of pedaling the cycle.

 

I can manually calculate each load case Fx,Fy and Fz component and give accordingly for 20 steps. My question : Is there any other way that giving initial load that is load at TDC Fx,Fy and Fz value and the next consecutive load cases  for the next 20 degree, then 40 degree and so on the value has to decrease ? , Because for 20 steps we can calculate what if there is a component with 1000 loadsteps.  the values of Fx,Fy and Fz cant be calculated manually it will make the person frustrated. So there has to be a way as a factor ( with this initial factor the consecutive load has to change either decrese or increase). Is there a way to give a initial factor or way to implement all other corresponding loads ? It would be much appreiciated if I get any positive response . I have attached  a sample pic of my model with just 4 load cases with certain angle apart. It was easy to do by calcualting Fx,Fy and Fz values. But if i want to implement more loads by dividing 360 by so and so ...

 

Thanks in advance for the response.

 

Kind Regards,

Muthu,.
