摘　　要：由于加速度曲线的复杂性和运动行程问题,无法满足日常的控制器调试和测试需求。针对现有设备的局限性,文章设计一种加速度模拟测试设备,通过构建能实时通过SPI总线信号注入加速度信号的电路,实现任意碰撞加速度曲线的模拟。该设备加速度模拟准确、操作方便,能同时注入2路加速度,可设置加速度曲线,工程应用价值较高。Due to the complexity of acceleration curve and motion stroke,it can not meet the needs of daily controller debugging and testing.Aiming at the limitations of the existing equipment,this paper designs an acceleration simulation test equipment.By constructing a circuit that can inject the acceleration signal through SPI bus signal in real time,the acceleration curve of arbitrary collision can be simulated.The device can simulate the acceleration accurately,operate easily,inject two accelerations at the same time,set the acceleration curve,and has high engineering application value.
