GB/T 15168-2013Vibration and shock isolators measuring method for its static and dynamic characteristics (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 15168-1994 "vibration and shock isolators measuring method." This standard compared with GB/T 15168-1994, the main technical changes are as follows:

--- Modify the standard name for the "shock and vibration isolators static and dynamic performance testing methods";

--- Added "Terms and Definitions" section (see Chapter 3);

--- Added "static performance tests" isolator arrangement is described (see 5.3); Static load speed and the rated load deformation test methods (see 5.4.2)

--- revised static performance testing;

--- Revised static load - deformation curve Static test method (see 5.4.3);

--- Added "static performance test" in the "Creep test" (see 5.4.5);

--- Added "Ellipse" in the test methods were used to transmit force and seek input dynamic stiffness (see 6.4.1.3);

--- Combined with "dynamic performance test" on the basis of the exciting, exciting and constant load variable load excitation method as "excitation scanning" (see 6.4.2);

--- Revised the "dynamic performance test" in the "hammering" to "natural decay" (see 6.4.3);

--- Increased isolator "Dynamic Performance Test" in the "mechanical impedance test" (see 6.4.4);

--- Increased rigidity and impact shock loss factor performance parameters and test methods (see

7.4.3 and 7.4.5);

--- Increasing the nonlinear method description and impact properties of the test (see 7.4.7);

1 Scope

GB/T 15168-2013 is the Chinese national standard on vibration and shock isolators measuring method for its static and dynamic characteristics, in the field of metrology and measurement. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 18 September 2013 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 June 2014. Classification: ICS 17.160, CCS J04. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the test methods and static performance of vibration and shock isolators, dynamic performance, classification and testing principles and impact properties. This standard applies to all kinds of materials, and the use of linear and non-linear type isolator performance testing.
