    Ansys Bushing Joint Stiffness and Damping

    Hi everyone, I have a question about bushing joint in ANSYS. I'm using ANSYS 14 but will have access to ANSYS 15 soon. I'd like to effectively create a spherical joint which has some stiffness and damping in the rotational degrees of freedom (DOF's). I think I can do this by using a bushing...

    Detail View Best Practice

    Hi everyone, I have two questions about detail views: 1. Is it good/accepted practice to section a detail view on a drawing? 2. Is it good/accepted practice to create a detail view within a detail view on a drawing, nesting the detail views? Many thanks, Tom

    Custom 7.4V Battery Pack with Panasonic 18650 Cells

    Hi Everyone, I'm planning to build a 7.4V battery pack to power my bike light. My current battery has died as it was left for a long time. All cell voltages are now well below 2.0V so I've disposed of it. My pack will contain 4 x 18650 CGR18650CG cells in 2S2P configuration, as shown here. I...

    Water Bulk Modulus vs. Pressure

    Hi everyone, I'm having a bit of trouble finding a graph or table showing the change of bulk modulus of water with pressure. I have some limited data from the Roymech website, which gives the change of bulk modulus with pressure up to 200bar, but I need to extend the data further than this, say...

    Closed Loop Water Cooling System Model

    Hi Everyone, I would like to set up a thermodynamic/heat transfer model of the following system. The system is a closed system which cools an electronic device which is attached to a heat sink, the water circulates through tubes between the heat sink and a cold plate, rejecting heat to the cold...

    Autoclave Connections

    Hi Everyone, Could someone please explain to me the thread dimensions used on medium pressure autoclave connections (up to 20,000psi)? As I understand it, an "Autoclave" connection essentially consists of a UNF male thread on a cone ended tube, which is screwed into a matching female UNF...

    Thermal Expansion - Elastic and Plastic Deformation

    Hi Everyone, I have a general question here which may or may not be a stupid one but I'll ask it anyway. If a material, let's say mild steel for example, is heated up it will expand. When it cools it will contract again. Does a stress-strain curve as seen in typical tensile tests apply to...

    Layer issue

    Hi, Can anyone help me? I'm fairly new to NX, working on NX4. I am working in context on an assembly (we'll call it "assm"). I've created a part (we'll call it "part1") within the assembly and made it the work part, with layer 1 as the work layer. "assm" is still the displayed part. When I...
