Let’s Go Bowling with SOLIDWORKS Motion - Computer Aided Technology
Summary
) It was a great exercise to refresh my CAD modeling techniques, implement camera views and dig deeper into the rigid-body dynamics functionality of SOLIDWORKS Motion. The Professional Bowlers Association (PBA) website clarifies that “a ‘Brooklyn’ refers to a ball that crosses over to the other side of the head pin opposite the side it was thrown (i.e., a Brooklyn strike hit the 1-2 pocket for a right-hander).” More wisdom from the web says this “crossing over” originated as a reference to someone going from Brooklyn to Manhattan. In this case, the relatively hard aluminum material was ultimately used to properly handle the point contact involved and prevent unrealistic penetration of the ball into the lane surface. Here, I’ve positioned the ball as shown and started it straight down the lane with a velocity of 300 in/sec and a spin of 80 RPM with rotation about a line angled from the centerline – the way someone might add a twisting motion upon release to throw a curve. This is where the frictional characteristics of the 3D Contact sets comes into play, allowing the spin to influence the path of the ball as it rolls down the 60-ft lane before encountering the head pin!
