Impact Force Measurement - Ball Drop Test

The Ball Drop Test is a simple and convenient way of imparting a known impact force to test the strength of various materials. Engineers and designers use it to test the energy absorption capacity of materials used in such commonly used items as helmets, gloves, protection pads for hands, knees chest and other body parts. Our impact force measurement solution makes it easy to measure actual impact forces at up to 1 KHz data capture rate and display results live on a Windows PC or Tablet. Log and Plot the data easily as well as see the Peak Forces generated with our easy to use and economical tool.

I had a 110 lb object land on the back of my heel. How can I determine the amount of force that hit me?

[@justus1199]

Can this sensor be mounted vertically? And what is the range of force for this set up?

[@loadstarsensors]

Yes it can. We have capacities to 100K lb if needed! Whatever range you need.

Thank you, I will reach out to your customer service team with my requirements so you can guide me on which of your systems will work best for me.

Sir could you tell me when I drop Mobile phones whoes length is parallel to Earth surface at some distance why it's doesn't effect on screen....and another one why I drop Mobile hold its one corner the. Drop it then screen may damage why???

[@panikking6012]

So, not OP but the impact force is less concentrated, so when the corner hits the earth all of the impact is "soaked up" by the corner, but when the flat part of the phone hits the earth evenly the force is spread out a lot more, which means less damage, its similar to how if you are hit with a rock the size of your fist you might be hurt, but if the same rock is ground up into dust or even just way smaller rocks, it might not hurt at all

1KSps seems low. I wouldn’t test any lowers than twice that.

everything depend on interaction material type and velocity at contact for punch in glowes this 1 khz sytem is more than enough to catch true peak force but for such rapid impact like those steel ball well 1 khz is not enough and 2 khz also isint even that he drop those ball from relatively small hight =small velocity steel we can see that impact time was like 1/20 of a miliseconds 20 times less than time interval beewten which this setup measured force :x thatsugest algorythm somehow try to calculate more :x for catch very good graph from 0,05 miliseconds time contaact the system should have like 100 khz for 5 measured point on graph :x 200 khz for 10 points what shpuld give precise true picture of what really happen :x .

@@mociczyczki You are right 1KHz is enough to capture peak force and it depends on what type of analysis you are trying to perform. Most tests using impact are to understand potential damage to the material such as pseudo velocity shock response spectrum (in/sec) in frequency or time domain. Applying a low pass filter (or butterworth ) gives very similar results compared to a high frequency signal while speeding up computing time drastically. It also depends on the application environment of what your device may go into and it’s resonant frequencies.

We offer two solutions. One with a max 1 Khz effective data rate (1920 Hz sampling rate in the ADC) and another with a data rate up to 50 KHz. We like to use the second one with at least 10 Khz sampling rate for hard surface to hard surface impacts. Check out www.loadstarsensors.com/impactforcemeasurement.html for more information.
