### How do you test drop height?How do you test drop height?The test drop height varies with the weight of the packaged-product In. In. 1. Firstly, make sure the samples are good samples (Including visual and function). 2. Re-pack it to original condition, including any nylon packing straps if any. 3. Then, select suitable floor. The floor should be flat, rigid base such as steel, concrete etc. 4.Inspection carton drop test for product calculating drop test height from a g - qcinasia(plate) IMPACT AND DROP TESTING - PCB Piezotronics

For a simple drop test, where m = mass, h = drop height, g = acceleration of gravity, and v = velocity at impact, the conservation of energy equation is mgh = ½ mv2 The impact velocity is independent of mass. Solving from the conservation of energy equation above and neglecting drag forces caused by air resistance, velocity is calculated from:(plate) What happens if you drop a G peak?What happens if you drop a G peak?Dropping a test item from excessive height leads high G-peak values to damage the test equipment. On the other hand, dropping an item from a low height may not generate the required G-peak value and duration.Determination of Optimal Drop Height in Free-Fall Shock calculating drop test height from a g

### What is the optimal drop height?What is the optimal drop height?On the other hand, dropping an item from a low height may not generate the required G-peak value and duration. Therefore, prior to performing shock tests, an optimal drop height must be established to ensure that the resulting G-peak value and duration time match the required test values.Determination of Optimal Drop Height in Free-Fall Shock calculating drop test height from a g(plate) Cited by 2Publish Year 2014Author Chao-Rong Chen, Chia-Hung Wu, Hsin-Tsrong LeeDropped Object Consequence Online Calculator calculating drop test height from a g

Mass(m) x Height(h) x Gravitational Acceleration(g = 9.82m/s). The Joule is a unit of energy equal to the work done by a force of one newton acting through one metre. In terms of dropped objects, it is recognised that any object achieving 40 Joules or more is likely to result in a recordable (MINOR) incident or worse on impact with a human body.(plate) Determining Stopping Distance Using Only Drop Height (steel) x = h/(a/g) = h/g-force So, for example, you have an object falling 48 inches and the g-force limit is 40 gs. Plugging these into the equation, you get x = 48 inches/40 gs = 1.2 inches which will be the minimum amount of deflection needed from a padding. Factoring Stopping Distance and Sorbothane

### nah, this is more newton's work calculating drop test height from a g you want u = ?, given v = 0, a = 50g = 160ft/sec^2, t = 0.01s calculating drop test height from a g (u-v)/t = a then h = ? given mgh = 1/2*m*u^2 calculating drop test height from a gHi rb1957 I thought anything falling under gravity could only reach a maximum acceleration of 9.81m/s^2, I have missed something? desertfoxThe math may not reflect the actual test parameters. A typical shock test uses a half-sine or sawtooth waveform, which does not correspond to a ..desertfox calculating drop test height from a g it's the deceleration that's being asked for. IRstuff calculating drop test height from a g the OP asked a question and i gave him an answer (to the question) calculating drop test height from a g it's calculating drop test height from a gHi rb1957 Ahhhhhhhhhhh I see now, so the acceleration would be a -Ve, sorry just saw the positive figure's anyway I agree with your 4feet answer. d calculating drop test height from a gThanks guys. This seems reasonable for what i'm trying to achieve. DeanDean, Just be aware that your question as posed may not accurately reflect the actual test conditions. "50g for 10ms" implies a step function to a calculating drop test height from a gI think rb1957 has solved a different problem to what the OP wants. The problem with calculating impact acceleratrions is that you need to know the calculating drop test height from a gok, dean estimated the acceleration and the time interval calculating drop test height from a g sure, probably not much more than a guess. that's why i suggested he calibrate the t calculating drop test height from a gDisplacement velocity severity chartApr 08, 2007Impact load calculationMar 04, 2004See more resultsDetermination of Optimal Drop Height in Free-Fall Shock calculating drop test height from a g

Determining the height of the drop for a test item is an important step prior to performing the test. Dropping a test item from excessive height leads high G-peak values to damage the test equipment. On the other hand, dropping an item from a low height may not generate the required G (plate)Calculating drop test height from a g-shock value calculating drop test height from a g(steel) Aug 10, 2009RE Calculating drop test height from a g-shock value IRstuff (Aerospace) 10 Aug 09 16:29 Anyway, your best bet is to find different suitable surfaces, like different woods, different metals with different backings, and drop a an object with accelerometer mounted on it and see what level of shock you get as a function of height.
