Read moreTips for Choosing the Right Shaker and Chamber
The right test equipment is essential to successful product testing. When purchasing a new vibration testing system (shaker) or environmental test chamber, choosing the right model for your test requirements is important. This article provides tips to aid in making the right choice.
Read moreUsing Multi Sine Test In VCS
Developed by the automotive industry where Swept Sine testing is the standard, Multi Sine is a test type to that reduces the run time by running multiple sine tones simultaneously as opposed to the single sine tone of a standard Swept Sine test. Crystal Instrument’s Multi-Sine tests offer up to 9 simultaneous sine tone sweeps, covering the entire frequency band of the Swept Sine test in a fraction of the time.

This article examines the acquisition of modal characteristics from a bullet train wheel by performing experimental modal analysis. The wheel vibrations affect the dynamics of the wheel-rail interactions. Understanding these vibration characteristics will help mitigate the vibration and noise at high speeds.

Sine Sweep in High Frequency Range
Executing a sine vibration control test is a common method of verifying the performance of the manufactured product under real world conditions. However, there are various challenges that could hinder a successful sine sweep test. These challenges include system structural dynamics (resonances and anti-resonances present in the system), sensor placement location, measurement dynamic range, and sensor quality and mounting method.
Read moreModal Analysis of Disc Brake Rotor using EDM Modal
This article examines the acquisition of modal characteristics from a disc brake rotor by performing experimental modal analysis. Brake systems are required for safe vehicle operation. The major component of a brake system is the disc brake rotor. While braking, the excitation frequency level can match natural frequencies and this phenomenon of resonance can cause the brake to squeal, potentially generating unpleasant vibration and noise.

Watch the new Spider-80Ti video produced by Aakash Umesh Mange, Application Engineer at Crystal Instruments. The Spider-80Ti is a front-end from the Spider-80Xi hardware platform that enables temperature measurement. Spider-80Ti supports temperature measurements from Thermocouples and RTD (Resistance Temperature Detector) sensors.
Read moreHigh Resolution Random Control at Low Frequencies (Multi-Resolution)
Random control is a fundamental vibration test for various industries and manufacturers of products. The FFT based control algorithm transforms time signals to the frequency domain where analysis, calculation, comparison…average, (etc.) are done. The performance of Random control is determined by how well the FFT describes the system characteristics. Proper spectrum resolution must be chosen in order to avoid missing any desirable observations and to meet the requirement of the control performance.
Read moreVibration Tests for Seismic Qualification
To simulate equipment in a structure subject to earthquakes, vibration tests for seismic qualification utilizes different types of motion to effectively simulate the postulated seismic environment. Single frequency and multiple frequency are the two categories of motion that these types of motion fall into. Each category includes multiple waveform types for different cases.
