Company Introduction
We are North America Wave Spectrum Science and Trade Inc based in Morganville , USA. We are member of Tradekey.com since January, 2011. Our business is related to Business Services industry and we specifically deal in teaching equipment, teaching system, training, vibration instrument, sensor. Please find our product details below:Vibration Comprehensive Experimental Teaching System"Vibration Comprehensive Experimental Teaching System" is specially designed for colleges and universities of higher learning in the mechanical discipline, civil engineering structures and mechanics. Combined with higher theoretical courses of institutions, this system may provide students with a complete vibration experimental lab equipment and methods to enable them to learn through visual experiments and to deepen their theoretical understanding. The system is an essential teaching experimental equipment. Configuration of the data acquisition instrument, amplifiers, and sensors can also be used for scientific research and experiment with optional software of signal acquisition, process and analysis.Experiment 1.1 Measurement of Natural Frequency and Modal Shape of Simply Supported Beam Structure by the Method of Hammer Impact Experiment 1.2 Measurement of Natural Frequency and Modal Shape of Cantilever Beam Structure by the Method of Hammer Impact Experiment 1.3 Measurement of Natural Frequency and Modal Shape of Disc Structure by the Method of Hammer Impact Experiment 2.1 Determination of Damping Ratio (half-power bandwidth method) Experiment 2.2 Determination of Damping Ratio (Attenuation method) Experiment 3.1 Signal Processing and Spectrum Analysis (Software Only) Experiment 3.2 Signal Superimposed (Software Only) Experiment 4.1 Understanding of Mechanical Vibration Experiment 4.2 Measurement of Amplitude and Frequency of Simple Harmonic Motion Experiment 4.3 Measurement of Natural Frequency of Vibration System (Lisajours Figure) Experiment 4.4 Measurement of Natural Frequency of Simply Supported Beam (Method of Sine Wave Sweep) Experiment 4.5 Measurement of Natural Frequency of Cantilever Beam (Method of Sine Wave Sweep) Experiment 4.6 Active Vibration Isolation Experiment 4.7 Passive Vibration Isolation Experiment 4.8 Vibration with Single Absorber Experiment 4.9 Vibration with Double Absorber Experiment 4.10 Vibration With Oil Damper Experiment 4.11 Beat Vibration Experiment 4.12 Natural Frequency and Modal Shape of Two or Three Degree of Freedom String Experiment 4.13 Natural Frequency and Modal Shape of Multi Degree of Freedom StringMulti-function Rotor Experment Bench Teaching SystemThe experiment bench is mainly used for teaching demonstration and experiments for students. It is designed for the mechanics discipline of colleges and universities. The device is characterized as compact in structure, small in size, convenient for operation, and it can be used for various experiments of rotating machinery with its large number of demonstration items and advanced testing means.Contents of Experiment (1) Base vibration and shaft vibration and phase changes when rotor rotates at critical rotational speed(2) Critical speed measurement of rotating shaft(3) The influence of different rotor structure model on critical speed of rotor(4) Measuring the vibration modal of flexible rotors(5) Oil whirl and whip of sliding oil-bearing(6) Radial vibration and axis displacement (simulation) of non-contact testing shaft (Lisajours Figure)(7) Dynamic balance(8) Bode figure(9) Three dimensional analysis of real-time waterfall diagram of a rotorVibration Comprehensive Experimental Teaching System"Vibration Comprehensive Experimental Teaching System" is specially designed for colleges and universities of higher learning in the mechanical discipline, civil engineering structures and mechanics.
