我最近做的项目:
1.ShockResistance:
Shockprofile:1/2sin
Acceleration :3G
Durationofapulse:11ms
Onthe3axisX,Y&Z,positive&negative=>6directions
3shocksforeachdirection=>18shocksforthetest.
2.VibrationResistance:
Freqrange:10Hzto150Hz
Switchfreq:58to62Hz
f<60Hz:constantamplitude0,15mm
f>60Hz:constantacceleration20ms-²
10sweepcycleperaxis
3.JerkResistance:
3differentsproducttested,in3axis
Jerkprofile:1/2sin
Acceleration:15G
Pulseduration:6ms
Amountofjerk:500+/-10
Cadency:3jerk/sec
我的问题:
1.请帮忙解释JERK与shock的区别;
2.此次试验,JERK比shock试验严酷等级高,能否取消shock测试?
谢谢! |
