The results show that stiffnessofspring does not affect the injection rate, but the mass of will affect the needle valve closing response time.
结果表明，电磁阀铁心弹簧刚度对喷油规律没有影响，但其质量影响针阀落座响应时间；
2
The sliding displacement can be controlled by the right stiffnessofspring under the circumstance that the effect of isolation doesn't decrease too much.
而合适的复位弹簧刚度可以在不显著减小隔震效果的情况下有效地控制滑移位移。

The support brackets are simulated by springs when calculating shock response of a ship shaft system, and the stiffnessofspring usually takes an approximate value.
