Описание (английский):

This document specifies the requirements for a digital mock-up virtual assembly test (VAT) for mechanical products, which is suitable for guiding virtual assembly testing before physical production. The application of this document is intended to result in an effective VAT and efficient on-site assembly. This test is applicable to 3D nominal models with theoretically exact dimensions.

Overview

ISO 21143:2020 - Technical product documentation - Requirements for digital mock-up virtual assembly test (VAT) for mechanical products - specifies requirements for conducting a digital mock‑up virtual assembly test prior to physical production. The standard applies to 3D nominal models with theoretically exact dimensions and sets out a structured VAT workflow (preparation, implementation, review) to verify mechanical interface compatibility, detect interferences, and validate assembly feasibility and ergonomics.

Key topics and technical requirements

VAT process and workflow

Three phases: preparation, implementation, review.
Emphasis on test planning, model certification, environment configuration and closed‑loop verification.

Test plan components

Test objectives, tasks, methodologies, process flow, test bill of materials (BOM), and schedule.

Model preparation

Product models (allowing controlled simplification and lightweighting while preserving key geometry and kinematics).
Environment models (shop floor, tooling, fixtures).
Virtual operator models (ideal human models for ergonomics).
Model qualification and documentation requirements.

VAT implementation requirements

Interference inspection (static and dynamic): detect parts occupying the same space or unacceptable clearances.
Assembly feasibility analysis: analyze assembly sequences, paths and procedures; ensure movement mechanisms function correctly.
Ergonomics evaluation: use virtual operators to assess human factors and optimize assembly operations.

Review and reporting

Validate that preparation, plan, process and report requirements are met; document findings and corrective actions.

Practical applications

Early detection and resolution of fit, clearance and interference issues before physical prototyping.

Validation of mechanical interfaces across units, sub‑systems and integrated products.

Optimization of assembly sequences and shop‑floor procedures to improve on‑site assembly efficiency.

Ergonomics assessment to reduce workplace risk and improve operator accessibility.

Support for reducing prototype cost and shortening product development cycles through virtual assembly simulation.

Who uses this standard

Design and mechanical engineers performing CAD/CAM and DMU (digital mock‑up) activities

Manufacturing and process engineers planning assembly lines and tooling

Technical product documentation teams responsible for compliant design deliverables

Quality, validation and systems engineers coordinating supplier integration and pre‑production testing
