Honeysuckle MDA is a three-dimensional design software developed by Chinese engineers as part of the national 863 high-tech program. It is one of the 15 key projects aimed at advancing domestic CAD/CAM technologies. The software integrates the ACIS geometric modeling engine from Spatial Corporation, which is internationally recognized for its robustness and precision in 3D geometry operations. Over 170 commercial software applications, including Autodesk’s MDT, rely on ACIS, serving more than a million users worldwide.
In 2000, with support from the Tianjin Science and Technology Commission, Honeysuckle MDA2000 Enterprise Edition was introduced to 123 companies across various industries such as machinery, automotive, and motorcycle manufacturing in Tianjin. A total of 200 software licenses were distributed, and all users received professional training, leading to widespread acceptance due to the software's ease of use and powerful features.
Honeysuckle MDA2000 offers a comprehensive set of tools, including parametric feature design, assembly design, engineering drawing creation, advanced surface modeling, standard parts library, and realistic rendering. It enables users to perform 3D solid modeling, generate engineering drawings, and integrate with CAM systems for CNC machining. Additionally, it supports structural analysis, motion simulation, and secondary development, making it a flexible platform for diverse industrial needs.
**First, creating a gear using Honeysuckle MDA2000**
The involute equation for a gear is:
- $ r = \frac{R}{\cos(t)} $ (where $ t \neq 0 $, R is the base circle radius)
- $ \theta = \frac{\sin(t)}{\cos(t)} - t $
- $ z = 0 $
For a helical gear with modulus $ m = 2 $, number of teeth $ Z = 30 $, pressure angle $ \alpha = 20^\circ $, and helix angle $ \beta = 10^\circ $, the parameters are:
1. Pitch circle diameter: $ d = m \times Z = 60 $
2. Addendum circle: $ da = m \times (Z + 2) = 64 $
3. Dedendum circle: $ df = m \times (Z - 2.5) = 55 $
4. Base circle: $ db = d \times \cos(\alpha) = 56.38 $
5. Base tooth thickness center angle: $ \theta = \frac{180}{\pi} + 2(\tan(\alpha) \times \frac{180}{\pi} - \alpha) = 7.708^\circ $
The angle between two teeth: $ \beta = \frac{360}{Z} = 12^\circ $
The base crest center angle: $ \gamma = \beta - \theta = 4.292^\circ $
**Second, the step-by-step process of creating a gear in Honeysuckle MDA2000:**
1. Create a cylinder with dimensions $ \phi64 \times 10 $ on the DTM2 plane.
2. Use the "Tools -> Sketch Features -> Function Curves" command on plane 3. Input the equation: $ r = 28.19/\cos(t) $, $ \theta = \sin(t)/\cos(t) - t $, $ z = 0 $. Set the start parameter to 0.0001 and end parameter to 0.5.
3. Draw an auxiliary axis on DTM3, forming a 4.292° angle with reference axis 1.
4. Repeat step 2, using the auxiliary line from step 3 as the x-axis.
5. Sketch a circle with center at the origin and diameter $ \phi55 $ on DTM3, then trim the excess portion.
6. Use the "Features -> Plane" command to create a new plane, then apply a "Stretch Surface" operation to generate a helical groove.
7. Perform a "Surface Difference" operation to form the gear tooth profile, and use a "Circular Pattern" to replicate the tooth around the gear.
This detailed process demonstrates how Honeysuckle MDA2000 enables efficient and accurate 3D modeling of complex mechanical components like helical gears.
