Innovating High-Performance, Action Bowling Ball Cores with SOLIDWORKS
The Hook: Radius of Gyration Meets Moment of InertiaBrunswick leveraged SOLIDWORKS software to develop the innovative bowling ball cores that have advanced bowling ball hooking performance. Using SOLIDWORKS, Brunswick can accurately model and control ball dynamics to produce designs that hook sooner or later on a lane, or perform better on oily, dry, or mixed lanes. “The hook spot, the point on the lane where the ball changes direction, is greatly influenced by the ball’s moment of inertia,” Koch explains. “We can control when and how much the ball will hook by varying the density of the materials used in a ball’s inner and outer core, and by altering the shape and mass of the inner core to increase or decrease the radius of gyration (RG), as well as the differential between the maximum and minimum RG. With SOLIDWORKS, I can clearly visualize the core design and use mass properties to maintain the integrity of design dynamics while changing the densities of the inner and outer cores to achieve the desired performance.”
Dynamic Topo Map for Bowling Ball CoresAs Brunswick continued to utilize SOLIDWORKS, Koch took advantage of the software’s automation flexibility to develop a macro that applies RG contours to bowling ball core designs in a manner similar to topographical maps. “Instead of lines showing differences in elevation, SOLIDWORKS lets me create contours that show variations in the RG,” Koch explains. “The macro uses SOLIDWORKS mass properties to measure the RG at different planes and fixed points and a coordinate system to apply lines similar to longitude and latitude. The macro then maps RG levels by contours,” Koch continues. “With these RG contours, I can gauge how the axis of rotation will migrate on a design, which is extremely beneficial when designing more sophisticated, performance bowling balls.”
Core Adaptations Spawn DV8With SOLIDWORKS, Brunswick developed ball cores that extended the range of performance variations in Brunswick bowling balls, and created and introduced an entirely new line of bowling balls under the DV8 brand. With model names like Deviant, Ruckus, and Zombie, the DV8 targets a younger audience with brighter colors, an edgier look, and more active performance. “On DV8 cores, we’ve created high-performance hooking balls that have more identifiable cores—some with more angular shapes and others with recognizable characteristics like a skull,” Koch says. “Using SOLIDWORKS, we can quickly develop cores to achieve new levels of performance, and then use PhotoView 360 to produce ball core cutaways for marketing materials for both Brunswick and DV8 bowling balls.”
