This section helps to give you specific warnings representing your spring design as well as giving you tips on how to make modifications or improvements so that you have a good spring design. You are also given our force chart in case you require your spring to be stronger or weaker. For more force, you would have to make the outer diameter smaller, take some coils out, thicken the wire diameter, or add more travel by augmenting the coil spring’s free length. To make your spring weaker, you would have to do the contrary; make the outer diameter larger, add some coils, thin out the wire diameter, or make less travel for your load by making the free length shorter. The warnings and tips (solutions) you might get are the following:
Warning: Your index is too small (below 4) which makes it difficult to manufacture.
Tip: In order to increase your index you will need to increase your outer diameter or decrease your wire diameter.
Warning: Your index is too large (above 15).
Tip: In order to decrease your index you will need to decrease your outer diameter or increase your wire diameter.
Warning: Your free length is less than or equal to your solid height.
Tip: You have entered a free length that is not possible based on your other inputs. To fix this, here are some options: increase the free length, decrease the number of coils, or decrease the wire size.
Warning: Your inputs have generated invalid or negative answers
Tip: Please adjust your inputs accordingly.
Warning: The force in L2 is less than the force in L1.
Tip: Your L2 must be greater than your L1. The formula for load is: rate * distance traveled = load. Thus if your distance for L2 is greater than L1, your load at L2 must be greater.
Warning: Your loaded height exceeds the maximum safe travel
Tip: If you need to travel a certain distance that takes you beyond the max safe travel, here are some options: increase huber of coils, increase outer diameter, or increase wire diameter.
Warning: Your load exceeds the max safe load.
Tip: If you need to reach a load that takes you beyond the max load, you ned to change your input values. Here are some options: increase the number of coils, increase outer diameter, or decrease wire diameter.
Warning: Loaded height / solid height conflict.
Tip: Your loaded height cannot exceed your solid height. To solve this problem, here are some options: readjust your loaded height, decrease your number of active coils, or decrease your wire diameter.
Warning: Your spring may buckle.
Tip: If your spring is not placed in a hole or over a shaft and has a free length divided by mean diameter greater than 4, you run the risk of the spring buckling while being compressed. To fix this problem here are some options: place the spring over a shaft or in a hole, increase the wire diameter, or shorten the free length.
