摘要

为实现滑雪运动时雪板受力情况的测量分析，需要开展雪板测量系统的研制开发。在总结分析已有类似产品使用问题的基础上，采用2个三维力传感器组合的结构布局、信号调理与无线传输相集成的电路设计，成功研制一种雪板五维力测量系统。该系统具有较高的刚度、固有频率，较好的动态测量性能。三分量传感器的静态精度优于0.2%FS，静态准度优于0.4%FS。应用本系统进行着陆冲击的动态性能测试，测试结果与理论分析具有较好的一致性。测试过程各传感器的各元回零良好，动态性能稳定，测量载荷规律合理。该系统的成功研制，为滑雪、滑冰等运动的多维力测量系统的研发提供了借鉴与参考，为体育运动测量系统国产化及自主可控奠定了良好的基础。

Abstract

In order to measure and analyze the forces on skis during skiing，It is necessary to develop the snowboard measuring system.On the basis of summarizing and analyzing the use of similar products，the integrated circuit design of signal conditioning and wireless transmission，and two dimensional force sensor combination were adopted，a five-dimensional force measurement system for snowboard was developed successfully.The system has higher stiffness，natural frequency and better dynamic measurement performance.The static accuracy of the three-dimensional force sensor is better than 0.2%FS，and the static accuracy is better than 0.4%FS.The dynamic performance of landing impact is tested by the system，and the test results are in good agreement with the theoretical analysis.In the testing process，all the sensors return to zero well，the dynamic performance is stable，and the law of measuring load is reasonable.The successful development of the system provides reference for the research and development of multimensional force measuring system for skiing and skating，and lays a good foundation for the localization and self-control of sports testing device.
