Steps
Step 1
Design Task Analysis
This step conducts in-depth analysis of mechanical engineering problems, clarifying design requirements and constraint conditions. Mechanical design requires comprehensive analysis from functional requirements, load conditions, working environment and other aspects, determining design inputs and technical specifications. Lay the foundation for subsequent scheme design through requirements analysis and failure mode analysis.
• Analyze machine functional requirements and performance specifications, including motion parameters, power parameters, accuracy requirements and life requirements
• Determine load conditions and working environment, calculate nominal load and design load, considering dynamic load, impact and fatigue effects
• Identify main failure modes (fracture, deformation, wear, corrosion, instability, etc.), determine corresponding design criteria
Deliverable: Design requirements analysis report (including functional requirements, performance specifications, load analysis, failure modes, design criteria) | Quality standard: Clear requirements, in-depth analysis, accurate loads, reasonable criteria
Step 2
Transmission Scheme Design
This step performs scheme design of mechanical systems or components, translating functional requirements into specific structural schemes and parameters. Mechanical design is the core of mechanical engineering, requiring balance among strength, stiffness, life, manufacturability and economy. Adopt three-stage method of conceptual design, preliminary design and detailed design, gradually refining design schemes.
• Perform overall scheme design, determine transmission scheme, structural layout and main parameters, draw mechanism kinematic diagram
• Perform component design calculation, determine dimensions and materials based on strength theory, stiffness theory and fatigue theory
• Perform 3D modeling and assembly design using SolidWorks, UG or Pro/E, check interference and motion coordination

This step performs comprehensive verification of mechanical design, ensuring all components meet design criteria and standard requirements. Verification is a key link to ensure mechanical product quality and reliability, eliminating design hidden dangers through multi-dimensional inspection of strength, stiffness, stability, life, etc. Must perform systematic verification according to national standards and industry specifications.
• Perform strength, stiffness, stability verification and fatigue life estimation according to GB/T 3811 or relevant mechanical design standards
• Perform FEA verification of key components, compare with analytical calculation results, ensuring reasonable stress distribution and deformation
• Check design drawings and manufacturability, conduct manufacturability review and standardization review, ensuring design is manufacturable and assemblable
Deliverable: Verification report (including various verification results, FEA validation, manufacturability review, problem list, correction suggestions) | Quality standard: Comprehensive verification, accurate data, all indicators qualified, good manufacturability
