- I want to estimate impact force generated due to collision between rotating body and stationary object. Bolt assembly is in balanced condition with the spring force and centrifugal force. As the speed of the shaft increases , centrifugal force on bolt assembly dominates the spring force which results in outward motion of bolt and thereby colliding with horizontal lever which thereby shuts off the fuel. Can you please guide me how to estimate impact force here.
Bolt comes out by distance d=1.58 mm when speed of rotation of shaft reaches its trip value (w_trip). m is mass of trip weight (Bolt assembly)
One of the approach which I had considered is work energy theorem.
Initial energy = 0.5m*(w_trip*(r+d))^2
Final Energy= 0.5m*(w_trip*r)^2 (Assuming bolt will come back at a distance r (original position) just after impact, and speed will be remain same just after collision)
Workdone = friction force at knife edge (intermediate lever) * knife edge thickness at interface
I want to estimate mass (Bolt assembly(Highlighted))required to produce this work done or in other words, impact should be able to trip the system.
Is this a correct approach?
Can I get to know impact force coming at impact?
