摘　　要：撑杆跳高运动插斗处动态力的测试受到多种因素的影响 ,分析测力平台在测试中的受力状态 ,指出装置的设计中应重点考虑装置的实用性 ,分析其刚性、质量及阻尼的影响 。The results of the test of dynamic force of the planting box on pole vault were affected by many factors. This paper analyzed the force condition of the force platform during testing. It also put forth that the practicability of the device should be mainly considered in the design of the device. Besides,the effects on the rigidity,mass and damp of the force platform were analyzed. At last,its accuracy of the measurement was improved on the basis of the maximal limitation of the simplified structure.
