Simulation Results

The nonlinear oscillations and resonances of the spring pendulum are experimentally and theoretically investigated. A unified by electromagnetic induction method of excitation, dissipation and registration of nonlinear oscillations is proposed. Experimental results demonstrate typical nonlinear effects, such as nonisochronism and bistability of vibrations. A theoretical model of the oscillatory system, leading to the Duffing equation, is proposed, an analytical solution and numerical simulation results are given, which agree well with the experiment.

Comparison Data

A novel method proposed in the production of Calophyllum inophyllum biodiesel has been investigated experimentally. In this study, we report the results of biodiesel processing with electromagnetic induction technology. The method used is to compare the results of Calophyllum inophyllum biodiesel processing between conventional, microwave and electromagnetic induction. The degumming, transesterification, and esterification process of the 3 methods are measured by stopwatch to obtain time comparison data. Characteristics of viscosity, density, and Fatty Acid Metil Ester (FAME) were obtained from testing of a Gas Chromatography-mass Spectrometry (GCMS) at the Polytechnic Chemistry Laboratory of the State of Malang. The results show that the biodiesel produced by this method satisfies the biodiesel standards and their characteristics are better than the biodiesel produced by conventional and microwave methods. The electromagnetic induction method also offers a fast and easy route to produce biodiesel with the advantage of increasing the reaction rate and improving the separation process compared to other methods. This advanced technology has the potential to significantly increase biodiesel production with considerable potential to reduce production time and costs.
