Modular virtual assembly design of double-track power chassis

In order to address the issues of low mechanization level and heavy labor intensity of manual film mulching and ridging in hilly and mountainous areas, a small double-track power chassis and relevant farming equipment are designed. Taking advantage of the top-down method and entity modeling in 3D (3-dimensional) design software Solidworks, a micro-rotary ridger was designed based on the virtual assembly technology. Through 3D modeling, assembly simulation test and interference analysis, structural faults were identified and modified. Finally the virtual assembly model was built. After drawing conversion and some necessary modification, the 2D engineering drawings for guiding production were rapidly generated by Auto CAD (Computer Aided Design). This computer aided method greatly improved the design efficiency and guaranteed the validity of the machine´s structure. Experiments indicate that this machine has excellent hill climbing capacity, strong tractive and appendiculate performance, good operating stability and high passing ability in soft farm lands.
