Introduction

The WorldSID 50th percentile male side-impact dummy is an important testing tool for evaluating the side-impact protection performance of automobiles.

Requirements, calibration methods, and mechanical requirements of electronic subsystems are of great significance for evaluating dummy performance and for further advancing automotive safety testing.

The development of crash test dummies, and the formulation of GB/T 47804 "Design and Performance Specifications for Road Vehicle WorldSID 50th Percent Male Side Impact Dummy" the standard GB/T 47804 is proposed to consist of four parts.

---Part 1: Terminology and Symbols. The purpose is to standardize the terminology and symbols used for the 50th percentile male side-impact dummy in WorldSID.

Numbers, subscripts, and abbreviations.

---Part 2: Mechanical Subsystems. The aim is to standardize the performance of the 50th percentile male side-impact crash test dummy according to WorldSID.

Calculation, calibration method, and dummy structural dimension measurement method.

---Part 3: Mechanical Requirements for Electronic Subsystems. The aim is to standardize the 50th percentile male side-impact crash test dummy according to WorldSID.

Sensor requirements.

---Part 4: User Manual. The purpose is to standardize the assembly and disassembly requirements for the 50th percentile male side-impact crash dummy according to WorldSID standards.

Requirements for human joint adjustment and positioning.
