RESEARCH ON IMPROVING THE FUNCTIONAL CHARACTETISTICS OF THE DOUBLE BAS BOW

Abstract

The aim of this paper is to develop a novel type of double bass bow that allows for precise center of gravity adjustments according to the user's preferences both before and during performances. The article introduces five different design variations aimed at achieving this balance adjustment. Calculations were conducted to determine the forces acting on the bow rod, and all design variants underwent Finite Element Analysis (FEA) testing. These tests looked at eight different materials, including ABS, Nylon, Carbon Fiber, Aluminum Alloy, 2x Steel Alloys, Copper Alloy, and Brass. The study findings point to the 7075-T6 aluminum alloy variant as the most optimal choice due to its favorable weight, elastic properties, and mechanical strength. Two types of weight adjustment elements were devised to enable precise bow weight customization. Considering these comprehensive results, a prototype of the bow was manufactured, demonstrating the innovative method for center of gravity adjustment during performances.
