Abstract
An analyzer that can provide information concerning a golf shaft assembly's oscillation properties, its natural frequency and its flat line oscillation planes. In the embodiments presented, a clamping assembly holds both the golf shaft assembly and an oscillator. Oscillation of the golf shaft assembly and that of the oscillator with known oscillation properties provides information about the golf shaft assembly's oscillation properties. Some of the test procedures presented are made possible by oscillation coupling between the golf shaft assembly and the oscillator. Oscillator assemblies are presented which have adjustable natural frequencies and one has a preferred oscillation deflection plane.
Claims20
An oscillation analyzer for a golf shaft assembly, the analyzer comprising:
- an oscillator having known oscillation properties including a first natural frequency when oscillating in a first deflection plane and a second natural frequency when oscillating in a second deflection plane;
- an oscillation of the golf shaft assembly and of the oscillator;
- an oscillation coupling means which can couple oscillation of the golf shaft assembly to that of the oscillator and in which the oscillation coupling increases as the oscillation frequency of the oscillator approaches the natural frequency of the golf shaft assembly;
- wherein the first natural frequency is farther from the natural frequency of the golf shaft assembly than the second natural frequency, thereby resulting in the coupling means being more effective for oscillator oscillation having the second natural frequency and the second deflection plane than for oscillator oscillation having the first natural frequency and first deflection plane;
- whereby the analyzer can provide information concerning the oscillation properties of the golf shaft assembly.
An oscillation analyzer for a golf shaft assembly, the analyzer comprising:
- a clamping apparatus to hold the golf shaft assembly;
- an oscillator attached to the clamping apparatus;
- an oscillation of the golf shaft assembly and of the oscillator, the oscillation of the oscillator having known properties;
- wherein the clamping apparatus provides an oscillation coupling between the golf shaft assembly and the oscillator and in which the oscillation coupling increases as the oscillation frequency of the oscillator approaches the natural frequency of the golf shaft assembly;
- wherein the oscillator has a flexible member with a first flexibility profile in a first deflection plane and a second flexibility profile in a second deflection plane whereby the oscillator has a first natural frequency when oscillating in the first deflection plane and a second natural frequency when oscillating in the second deflection plane;
- and wherein the first natural frequency is farther from the natural frequency of the golf shaft assembly than the second natural frequency and therefore the oscillation coupling is more effective for oscillation in the second deflection plane with the second natural frequency than for oscillation in the first deflection plane with the first natural frequency;
- whereby the analyzer can provide information concerning the golf shaft assembly's oscillation properties.
