Vibration testing is used to simulate pot holes, curbs and off road use. All Rights Reserved. From sub-atomic particles all the way up to skyscrapers, internal movements and motions resulting from the absorption of energy make all objects vibrate to some degree. 3. The force produced by an exciter is mainly limited by the heating effect of the current. Vibration Test MIL-STD-202 Method 204 1. i.e. Furthermore, we construct a 115, Section 5: JOURNAL OF MATERIALS AND MANUFACTURING (2006). The final vibration test load specification for an automotive product can be presented in either sinusoidal sweep or random vibration profile formats, as per the customer preferred, and both will have an equivalent durability damage level for the given test duration and reliability parameters. BS EN 60068-2 IEC 60068-2-6 Vibration (sinusoidal) IEC 60068-2-27 Shock IEC 60068-57 Vibration (time history and sine-beat) Later, the acceleration was increased to 4.81 g in accelerated testing. The test results are shown in Table 2. No marking blurred. conditions. Home Services Test Test Capabilities Product Testing Vibration Testing Vibration Testing Vibration testing is commonly used as a method to recreate the fatigue stresses that occur during the life of an engineered product, assembly, or packaging as the product moves through the supply chain. From instrument panels to seats inside the car and from air-bag sensors to fuel injection pumps in the engine compartment, many automotive components are being tested to precise vibration patterns and levels. By Vanee Chonhenchob, Sher Paul Singh, Jay Jagjit Singh, Joseph Stallings and Gary Grewal . Measurement and Analysis of Vehicle Vibration for Delivering Packages in Small-Sized and Medium-Sized Trucks and Automobiles . detail specification Per product specification standard 7. The measured loads are divided into two types according to their original sources, the proving ground load data for body mounted products, and the engine load data for engine mounted products. EMIC Electrodynamic vibration test system for evaluating industrial products against vibrations. Basic theoretical backgrounds and a set of key technologies for vibration test specification, such as the load data process in the time and frequency domains, CAE simulation, durability evaluation, damage equivalence and reliability requirement are introduced. An'l so this monograph gives the vibration testing tech-nologist a reference that systematically reviews and explains how vibration data are acquired, how the data are used in preparing specifications, how a test is conducted to satisfy specifications, and how test results are interpreted. These standards depend on several factors including the type of part and manufacturer. Inductance shall not change more than ±30% 8.
