Dynamics Simulation of Capsule Filling Machine Based Virtual Prototype

Abstract

Capsule filling machine is the key filling equipment for pharmaceutical capsule preparations. Taking NJP3400 type of capsule filling machine as an example, we analyze its principle and characteristics successfully. First, we built its geometric model with Pro/E software, established the equations of motion of transmission mechanism with Lagrange multiplier method and showed the process of solving the equations with GSTIFF software. With the interface module called mechpro of PRO-ADAMS, the model was imported into ADAMS, and then, we analyze the machine’s strength, displacement, acceleration and the association of these parameters.
