Title:
【発明の名称】荷重支持部材における超音波測定への曲げの影響を最少化する方法
Document Type and Number:
Japanese Patent JP2002500752
Kind Code:
A
Abstract:
A load-indicating device including a load-bearing member adapted to deform when stressed. Ultrasonic waves are directed into one end of the load-bearing member and ultrasonic echoes are received at the same end by ultrasonic wave transmitting and receiving equipment. In one embodiment, ultrasonic waves are transmitted and received using an ultrasonic transducer disposed on either the head or the opposite end of the load-bearing member. The head, the end, the shank or a combination thereof are contoured to reduce the influence of geometric variations and asymmetrical stress in the load-bearing member on the ultrasonic measurement. A method is also provided, which encompasses a model, by which preferred geometries of the contoured surfaces of the load-bearing member can be designed. Also provided are a method of making a load-bearing member including contouring at least one end of a load-bearing member, or the shank to reduce the influence of geometric variations and asymmetrical stress in the load-bearing member on ultrasonic measurement, and a method of identifying a contour on a load-bearing member that will provide accurate and reliable ultrasonic load measurements.
