Hi,
I am a new PE member. I am not a physicist but would appreciate any and all assistance offered.
I am attempting to calculate the quantity of mechanical energy available at an automotive shock absorber. The end result of this exercise would be to replace the existing shock with an electrical generator. I would like to break down the exercise into manageable chunks, manageable for me. Please feel free to ask for more information, point out errors, etc. I am new to this and am in over my head.
Some real world data has been taken as a starting point. A linear measuring device was attached to the existing shock absorber. The zero point was set with the shock at rest approximately at mid travel. Data sampling was conducted at intervals of 1000 per second. This was collected for 65.534 seconds. To summarize. A table consisting of two columns, the first being the time index, the second being the distance from the "'zero" point. Makes up the data set we have.
The first step, calculate the total travel distance of the sensor during that time span. I separated the positive travel values and the negative travel values into two additional columns. Summed the positive values into a positive travel total, and the negative values into a negative travel total. Removed the negative sign from the negative travel total, summed it to the positive travel total. This gave me the absolute total travel of the sensor for the time span previously mentioned.
The next step, calculate velocity. With the travel distance of 3316.47 inches during 65.534 seconds resulted in an average velocity of 50.607 inches per second (rounded to three places). Reading the forums here at PE I understand that a mass value is also required. Please use the value of 100 pounds.
This is where my understanding ends. With an end goal of a power figure in Watts or Joules. how would one get there from here.
Thank you
