碰撞试验中,假人及传感器组成数据采集系统的第一部分,输出的数据反映了冲击环境中模拟人体的生物力学响应.因此,最终的数据结果非常重要.传感器激励电压的不同,产生的热量也不同.碰撞试验中使用的传感器数量达200多个,因此假人体内会因激励电压产生较大的热量,从而产生温度误差,最终引起数据的不准确.因此,在碰撞试验中,要确保假人体内温度与标准符合;要求传感器标定电压与数据采集输入的激励电压一致.
踫撞試驗中,假人及傳感器組成數據採集繫統的第一部分,輸齣的數據反映瞭遲擊環境中模擬人體的生物力學響應.因此,最終的數據結果非常重要.傳感器激勵電壓的不同,產生的熱量也不同.踫撞試驗中使用的傳感器數量達200多箇,因此假人體內會因激勵電壓產生較大的熱量,從而產生溫度誤差,最終引起數據的不準確.因此,在踫撞試驗中,要確保假人體內溫度與標準符閤;要求傳感器標定電壓與數據採集輸入的激勵電壓一緻.

The dummy and sensors constitute the first part of a data acquisition system during the crash test. The output data reflects the biomechanical response of a simulation human body under impact environment; therefore, final data results are quite important. The different excitation voltages of sensors usually generate different heat amount. There are more than 200 sensors which are used in the crash test. Hence, more heat amount may be produced in a dummy body due to excitation voltage, thus leading to temperature error. The incorrect data would be ultimately created. Therefore, it is guaranteed that body temperature of dummy conforms to standard during the crash test. Furthermore, it is also required that calibration voltage of sensors is always consistent with excitation voltage intended for data acquisition.
