This document is GB/T 47804 "Design and Performance Specifications for Road Vehicles WorldSID 50th Percentile Male Side Impact Dummy" Part 1 of GB/T 47804 has been published, including the following parts.

---Part 1: Terminology and Symbols;

---Part 2: Mechanical Subsystem;

---Part 3: Mechanical Requirements for Electronic Subsystems;

---Part 4: User Manual this document is modified to adopt ISO 15830-1:2022 "Road vehicles - Design of 50th percentile male side-impact crash test dummies".

Performance Specification Part 1: Terminology and Basic Principles.

The technical differences between this document and ISO 15830-1:2022, and the reasons therefor, are as follows.

---Changes were made to "Dedicated Upper Arm" (see 3.4, 3.5 in ISO 15830-1:2022) and "Rib Compression Sensor" (see 3.13).

The terminology in ISO 15830-1:2022, 3.16, "Calibration Seats" (see 3.17, ISO 15830-1:2022, 3.34) and Definitions should be developed to meet my country's technological requirements.

---The term "dummy mid-sagittal plane" (see 3.18) and its definition have been added to meet my country's technical requirements;

---The terms "1 to 2g setting joint", "aluminum honeycomb", "angular velocity sensor", "seventh cervical vertebra", "range", "round head screw", and "connection" have been removed.

"Linear", "Front", "Full Arm", "First Lumbar Vertebra", "Fifth Lumbar Vertebra", "First Sacral Vertebra", "Side Impact Dummy", "First Thoracic Vertebra", "Fourth Thoracic Vertebra" "Vertebra," "Twelfth Thoracic Vertebra," "Universal," "W50-," and their definitions (see Chapter 3 of ISO 15830-1:2022) are required to adapt to the needs of my country.

Technical requirements;

---Chapter 5 of ISO 15830-1:2022 has been deleted. This chapter describes the background and development process of dummy research and development, and is not applicable to my country.

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.

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.

3 Terms and Definitions 3.1 shoulder rib the first rib from top to bottom among the six ribs of the 50th percentile male side-impact dummy in WorldSID.

Note. The shoulder ribs consist of three parts. the outer shoulder ribs, the inner shoulder ribs, and the reinforcing shoulder ribs.

The second, third, and fourth ribs from top to bottom in the six ribs of the 50th percentile male side-impact dummy in WorldSID.

Note. Rib 1 is the second rib from the top in the dummy's six ribs, and rib 2 is the third rib from the top in the dummy's six ribs.

The third rib is the fourth rib from top to bottom among the six ribs of the dummy. Each rib consists of two parts. the outer rib and the inner rib.

Abdominal ribs

The two lowest two ribs among the six ribs of the 50th percentile male side-impact dummy in WorldSID.

Note. Abdominal rib 1 is the fifth rib from top to bottom in the dummy's six ribs; abdominal rib 2 is the sixth rib from top to bottom in the dummy's six ribs.

The ribs consist of two parts. the lateral ribs and the medial ribs.
