Non-sinusoidal Wave and Process Parameters of Anti-parallel Four-bar Linkage

Abstract

Abstract: Based on the non-sinusoidal generating device of elliptic gear, a non-sinusoidal oscillation generating device for continuous casting mould driven by anti-parallel four-bar linkage is developed, and its prototype is manufactured. The new device features compact and rational structure, high reliability, and easy realization of static and dynamic balances, so both its working performance and cost are superior to those of elliptic gear. Through motion analysis, the displacement, velocity and acceleration functions of the non-sinusoidal wave generated by anti-parallel four-bar linkage are obtained with simple formulas. The analytical formulas of the process parameters are deduced, and the variation rules with basal parameters of non-sinusoidal oscillation are analyzed. Through geometric parameters substitution, these formulas can be transformed into corresponding formulas of non-sinusoidal wave of elliptic gear, and the calculation is simple and can obtain accurate solution, thereby providing theoretical basis for accurate calculation of process parameters and accurate control of process in the practical application.

Key words: Anti-parallel four-bar linkage, Continuous casting, Mould, Non-sinusoidal wave, Process parameters
