Foreword
This standard replaces GB/T 6792-1996 "bus body skeleton stress, strain measurement method."
This standard compared with GB/T 6792-1996, the main changes are as follows.
--- Increasing the bus skeleton terminology explanation (see 3.1);
--- Delete the original standard equipment on specific aspects of fixation methods and damping terms (see the 1996 version 5.2.1 - 5.2.4);
--- Revised test equipment for specific requirements, such as. the "tape recorder" to "Data Acquisition System" (see the 1996 version 3; this
Chapter 4 edition);
--- Increasing the braking condition and vibration condition test methods in dynamic stress tests to distinguish vibration conditions and braking conditions (see 7.2);
--- Increasing the braking condition Test site requirements (see 5.2.3);
--- Increased vibration conditions bench test method (see 7.2.2).
The Standard Appendix A, Appendix B, Appendix C, Appendix D, Appendix E, Appendix F and Appendix G are informative appendices.
This standard was proposed by the National Development and Reform Commission.
This standard by the National Automotive Standardization Technical Committee (SAC/TC114) centralized.
This standard was drafted. National Bus Quality Supervision and Inspection Center, Zhengzhou Yutong Bus Co., Ltd., Xiamen King Long Engineering
Co., Ltd., Jinhua Youngman Automobile Manufacturing Co., Ltd.
The main drafters of this standard. Zhou Zhengping, Wei Jianhua, Duan Yong, Li Dongmei, Zhou Qin State, Fangfang.
This standard replaces the standards previously issued as follows.
--- GB/T 6792-1986, GB/T 6792-1996.
