Simulation Analysis of Clamping Mechanism of 4500t Die Casting Machine
Firstly,the working principle of the clamping mechanism of a die casting machine is introduced,and the comprehensive analysis of the clamping mechanism is conducted.The mathematical model is established and the key parts'motion formula is got.Using 3Dmodeling software,the 3Dmodel of the clamping mechanism is set up,and the kinematic simulation analysis of the die casting machine based on the actual working conditions using ADAMS software is carried on,the optimal critical angle of clamping mechanism is given.By using the software ABAQUS,the mechanism strength analysis is got which verifies the rationality of the clamping structure.It provides the guarantee for stable work of the die casting machine in practice.
We present a method for synthesising control strategies for continuous dynamical systems. We use Uppaal Tiga for the synthesis in combination with a set-based Euler method for guaranteeing that the synthesis is safe. We present both a general method and a method which provides tighter bounds for monotone systems. As a case-study, we synthesize a guaranteed safe strategy for a simplified adaptive cruise control application. We show that the guaranteed strategy is only slightly more conservative than the strategy generated in the original adaptive cruise control paper which uses a discrete non guaranteed strategy. Also, we show how reinforcement learning may be used to obtain optimal sub-strategies.
