steering Wheel Dynamic Shock Schedule
acceleration:12g's perpendicular(toward the 12:00 rim position) and axially(relative to the steering column shaft) measured at the steering column/wheel fastener(see Figure 2).
Nominal Shock Duration: 10ms
Nominal Shock shape: sine Wave
Number of Shocks: 10 at each specified orientation.(the steering Wheel shall represent the range of in-vehicle orientations) standard testing orientations are the in-vehicle design postion ,column full up and column full down steering wheel positions.
Test Method:
1 apply 12g (perpendicular and axially at the wheel fastener)10 times at each orientation
2 monitor steering wheel horn contact duration
3 horn contact duration shall be less than 5ms
以上是某个振动测试的试验方法 我估计是固有频率测试 加速度12g 测试时间是10MS!!!就是10毫秒。。。每个方向周期10次 也就100毫秒。。。有这种测试吗?但是看到第三条,难道是异音测试?请高手99我!!!
