Strike oscillograms to compare

1: The foreign car factory accelerates the deceleration oscillogram of the rule

(1)


Diagram showing the four seismic, shock waves from small to big, showing spring shape, 0.07 seconds seismic force (destructive) the most, bear the serious distortion of the body, burning cars and casualties have occurred at this point, shock force of about -500,000 (mm / s) fulltime is about seventy thousandths seconds.

2.Taiwan AUTOMOTIVE RESEARCH & TESTING CENTER: Deceleration oscillogram

(2)


Fig. (2) Data won examined on the car body structure of the sensor, strike it from 5.35 seconds till 5.37 seconds, belong to motive force to strike, is also called the main seismic zone, 5.35 the amplitude of vibration is the largest from second to 5.37 seconds, it is greatest too to destroy strength. 5.37 Belong to the striking which does not have motive force from second to 5.43 seconds, is also called the aftershock area. Deceleration 33g ,about 404662 Newton strength.
Note: 1g=9.81m/s ^ 2 , Quality of the car about 1250 kg

3.the Defend safety system: absorb shock oscillogram

(3)


Diagram showing two shock waves, from 5.35 to 5.358 as the first main shock area, the impact shock-absorbing handle the pressure without the system, amplitude 140kgf/cm ^ 2.

Note: The sensor is to the system front, please consult the Fig. five (15).

4.the Defend safety system: absorb shock oscillogram

(4)


Diagram showing two shock waves, shock waves from large to small, showing reservoir shape, the amplitude of the initial shock after shock-absorbing pressure 140kgf/cm ^ 2 in four thousandths seconds down to 68kgf / cm ^ 2, after showing a U-shaped slot, said crash cushion safety systems has been completely absorbed shock pressure, body structure to reduce the load, the body is not easy deformation, the probability of casualties has decreased dramatically, also known as sponge effect, is The only security the world's most user-friendly products.
Note: The sensor is to the system back end, please consult the Fig. five (16).

Fig.(4)With Fig.(3)Compare, the amplitude of vibration drops and reaches 72 kgf/cm ^ 2, strike the strength of shaking and lighten 72kgf/cm ^ 2, prove this system can absorb shaking strength, relative 50% of the safety coefficient of improvement car body and personnel of 50%.
