Mechanical design practice course, let students do something
- this process appears simple, it is a complex process, such as simple and fitter tools: drill and tapping, need to work in the process of careful experience that is absolutely useless empty talk, feed on illusions. No matter what other enterprises, you have to come up with real technical ability.s
How to design the common mechanical parts with CATIA, and how to solve the problem when the units are inconsistent?
- Very simple. Write the value / conversion value of the drawing in the parameters
Can the bearings used in the design of mechanical equipment be used as part drawings?
- (4459.7 GB/T 1998) for the following provisions: (1) the basic regulations and general characteristics of drawing, drawing, drawing in the various provisions of symbols, rectangular wire frames and contour lines are drawn with thick lines. When drawing a rolling bearing, the size of the rectangular frame and the outline of the outer frame should be consistent with the shape dimension of the rolling bearing (found in the manual) and the same proportion as the drawing. In the cutaway view, when drawing the rolling bearings by the universal drawing and the characteristic drawing, the section symbols (section lines) are not drawn. When drawing with the prescribed drawing method, the rolling body of the bearing does not draw a section line, and each ring can be painted in the same line section with the same direction and spacing, as shown in Figure a. Such as bearings with other parts or accessories (such as eccentric sleeve, tight sets, retaining rings, etc.), the profile line should be in line with the ring profile in different directions or different intervals, as shown in Figure B. Omission is not allowed in drawing without misunderstanding.s
Mechanical design of various parts of the hardness value of how to determine?.
- Give your reference value, heat treatment is most hard, probably 65HRC, this is the limitAnd 45 steel without heat treatment, only about 10When you design, the hardness does not require a material can be set, there are hardness requirements, then the technical requirements of hardnesss
Why do the design of mechanical parts (flanges and elbows) be based on the yield limit?
- Hello friends, usually to do the experiment to the material ontology; have tensile, bending, impact, flattening, flaring, cyclamic, normal temperature test 20 degrees Celsius, is 20 degrees Celsius, minus 20 degrees Celsius, the test to the material, to be determined after completion of the test material meets the design requirements. Is the so-called (to yield limit for design basis?)s
Does the SolidWorks mechanical design engineer paint parts individually or draw parts in an assembly?
- There are two ways, corresponding to "bottom up" and "top down" two design methods.s
How does the Auto CAD menu bar do not have the "mechanical parts design" command?
- 1, will download the atuoCAD mechanical design package unpacked to atuoCAD20** installation directory.2, access to atuoCAD - tools - Options - files - the path to adding atuoCAD mechanical design packages to support file search paths.3, enter the "custom" tool - - - "transmission interface, select the main CUI file in the box at the top of the left column, the choice of transmission interface (acad.cui); the box open at the top of the mechanical design package transmission interface on the right side of the column selection, selection of mechanical design: inside the package.Cui file, start menu items you can see, the design of mechanical parts in the following.4. Expand the menu items in the left and right columns, and drag the design of the machine parts in the right column to the end of the menu item in the left column, and click the Save button at the top of the left column. Click apply to confirm!5, in the command line "menu", select "Support" under the acad.CUI file open, you will see the machine parts design menu hung up!s
Are there any 3D mechanical design software that can simulate the mechanical movement of parts?
- Commonly used simulation parts mechanical movement software, ADAMS and SolidWorks Motion module.ADAMS is a professional CAE software, the automatic dynamic analysis of mechanical system (Automatic Dynamic Analysis of Mechanical Systems), the software is the U.S. Mechanical Dynamics Inc (Mechanical Dynamics Inc.) (now part of MSC) the development of virtual prototype analysis software. ADAMS software uses an interactive graphical environment, and part library, library, library capacity constraints, the mechanical system to create fully parametric geometric model, Lagrange equation method of multi rigid body dynamics in the solver using system equations, statics kinematics and dynamics analysis, the virtual machine system, output displacement, speed, acceleration and reaction force. The simulation of ADAMS software can be used to predict the mechanical performance, range of motion, collision detection, peak load, and input load of finite elements.The Motion module of SolidWorks constructs the coordination relation through the constraint form among parts, and completes the simulation of motion between parts.s
