Batch Addition Method of Contact in Dynamics Simulation

Taking the special ammunition feeding system for a certain unmanned platform as an example, this paper introduces batch addition method to replace manual addition of the contact between bullet and the gun body by means of macros combined with cyclic function. With the verification of contact between 50 bullets and the core body, the adding efficiency can be improved by 88%, and the repetition and missing items in the manual adding process can be avoided at the same time. This method can be widely used in the simulation of similar structures such as chain drive system, automatic weapon feeding system for continuous shooting and track system.
