how to apply limit distance on spline

Iskandar Dzukarnain Mohd Kamil Jan 3, 2017 3:22 AM

Hi Guys,

I am new here.

I have a question on how to apply limit distance on spline.

As you can see from the animation i created, the hoist is moving along the bracket and the cable (spline) is moving with it together.

How can i make sure the cable (spline) from Point 1 and Point 2 is stop at certain distance?Refer image below

Please help me on this.

Thanks.

Hello Iskandar,

One idea would be to dimension the length of the spline (can do this since SW2013?) and then just make sure that it's ends are constrained in-context of the assembly so that it's shape can update.

  Hi Mark,
  
  Thanks for your response.
  As you can see from the video, i have constrained on both end of the spline (in context as you mentioned) and also have applied the spline length. Currently using SW2016 SP5.0.
  
  What i mean is that, when i pulled the hoist, the hoist will stop when distance from Point 1 and Point 2 is 100mm.
  Is there any way to do this?
  
  Thanks
  Iskandar

    Hi Iskandar,
    Can you not apply a distance limit between the two carriages that hold the cable (spline) so that those two carriages will only separate to a maximum distance that allows 100mm of 'droop' or 'slackness' in the cable (spline) thereby giving you your distance between points 1 and 2?
    
    Dave.
    
    *** EDIT ***
    
    In a 'real' industrial application, I have seen where there would be a lightweight chain or stranded cable running between the individual carriages. The length of the chain or cable is slightly shorter than that of what your 'spline' would be therefore always leaving an amount of 'slack' in the 'spline' and eliminating any unnecessary wear and tear on whatever your 'spline' may be, e.g. electrical wiring, fluid hose etc.

      Hi Dave Bear
      
      Thanks for your response.
      If i not apply limit distance between two carriage, how do i make sure Point1 and 2 will stop at 100mm?
      I want the spline to be freely manipulate and have a certain min distance between Point1 and 2.
      
      Is it possible?
      
      Thanks
      Iskandar

        Hi Iskandar,
        I'm not sure, To apply the limit only to the spline is above my level of knowledge which is why I suggested the carriage option.

        A limit mate can have a minimum as well as a maximum dimension, ie:- 100mm to 1000mm
