Hello All- Does anyone know of a place to download a reasonable accurate, somewhat aesthetic, model of a female head. I am designing a bluetooth headset and want to render the model on a female head to show the customer. Either paid or free sites will work. The model has to be solidworks...

electicpete- Thanks for the chart. Its not exactly what I was looking for but it is really nice and will help me until I can find what I am looking for. Thanks a bunch!

Hello All- I am looking for a data plotting utility like Excel that allows the user to make dynamic, zoomable plots like those on Google Finance like this: http://finance.google.com/finance?q=INDEXDJX:.DJI%20INDEXNASDAQ:.IXIC%20INDEXSP:.INX I have a large set of data that needs to be...

It is a face seal that gets slowly rotated. Imagine a cylinder with a hole through its center. Now the end of the cylinder is pushed up against a flat plate with a hole through its center. Fluid (water) must pass through both the cylinder and plate, so a face seal on the end of the cylinder is...

Thanks for the responses. Unfortunately, due to friction constraints, I can't design the gland at the parker recommended squeeze. We have to use considerably less squeeze. So far, we have used an experimental approach of finding the least amount of squeeze that holds the system pressure (fairly...

I am looking for data regarding maximum fluid pressure verses o-ring squeeze. I am designing an o-ring face seal and would like to know what maximum pressures the seal could hold at different amounts of squeeze. Thanks in advance for the help!

I am driving the motor with a L6202 H-bridge driver chip.

Can anybody point me towards a good reference (preferrably and internet article) about PWM DC Motor Control? I need to control a small 5V DC motor so that it quickly moves to a specified position and holds that position untill commanded further. I am currently using a software algorithm that...

Yeah, that ball problem was just an example to explain what I am trying to do. The acutal problem is the pressure problem that I explained in the original post. My object has uniform pressure distribution on all external surfaces. In reality, the entire object will be "squeezed" toward the...

Thanks for the responses- jte- I am using Cosmos thru Solidworks cbrn- This is a tough topic to convey, so let me explain it by describing a model. Say you have a model of a ball supported by a spring to ground. In addition to the spring, you have a point force on the ball pushing in the...

Hello Everyone- Is there a way to measure the deformation of a model in Cosmos? The deformation plot appears to measure the departure of the model from it's orignal shape as opposed to the displacement plot that measures the departure of a point in the model relative to ground. Is there a way...

Additional Note: -The structure is plastic (non-conductive) -There are no direct metal-to-metal contacts or any other electically conductive paths betweeen dissimilar metals aside from the salt water My main question is whether dissimilar metals will produce a galvanic pair when immersed in...

I am testing a structure inside a stainless steel vessel filled with sea water. The structure has a brass fitting and several titanium fasteners. Neither the fitting nor fasteners come in contact with the vessel or each other but will be aprroximately 1 foot away from the vessel walls and each...

Two metals that form a galvanic couple (brass and 304 stainless steel for example) are immersed in salt water and near eachother (approx 1 foot apart), but not touching. Will the brass corrode? Is the salt water enough of an electrical conduction path to create galvanic corrosion? Thanks for...

Thanks for all the help you all, especially mickeymouse! That was exactly what I was looking for.
