基于开关原理国民体质测试器材可靠性检测的设备研究

摘要：

为解决我国基于开关原理国民体质测试器材可靠性检测设备现有技术中存在的不足，本文阐述了一款通过直流电机和曲柄连杆结构相结合，该设备的设计原理是利用直流电机的旋转带动曲柄连杆，实现对试样的循环加载，以此检测开关原理国民体质测试器材的可靠性，实现了对该类检测设备通用性、科学性、精密性的预期效果。

Abstract:

In order to solve the problems in the existing technology of the reliability testing device of the national fitness testing equipment based on the switch principle in China, this paper describes the design process of a kind of reliability testing device of the national fitness testing equipment based on the switch principle by combining the DC motor and the crank and connecting rod structure, and uses the rotation of the DC motor to drive the crank and connecting rod to realize the cyclic loading of the sample, realizing the expected effect of universality, scientificity and precision of the device for reliability testing.
