Hi,
The dual compression coil design shown works great. In assembly it is tightly surrounded by plastic molded parts and provides electrical connectivity between a battery and a circuit board.
Problem is that when received from the spring mfr, these parts are incredibly difficult to separate...
A piece of rubber the size of 4 stacked quarters is needed for shock/vibration protection of electronics. It has been determined for the application that a Shore 'A' hardness of 35-40 works best. Due to mass constraints, the rubber is too heavy.
Is there a method to calculate the EFFECTIVE...
I am not a materials engineer. I am looking for a compliant material with the following qualities:
1. Shore 'A' hardness of 30 - 50, preferably 35-40
2. Density of 0.5 oz/cu in (0.86gram/cc)
3. Able to be produced in a hemispherical shape of radius 0.85" inch, with a hollowed out hemispherical...
