The invention discloses a real-time needling track simulating
system. A needling effect picture is drawn and displayed according the following steps of 1, obtaining all coordinate information of needling of a needling
machine, setting a longitudinal dimension L of a needle plate of the needling
machine and a longitudinal forwarding step length s of a
fiber net, calculating needling frequency N ofthe needling
machine after a needling cycle is completed, and setting needling
simulation frequency M of the needling machine, wherein N is equal to a quotient obtained after L is divided by s; 2, obtaining initial needling point distribution information; 3, adding s to each ordinate of all needling points in the initial needling point distribution information to obtain needling point distributioninformation of the second needling
simulation, and repeating the step till needling point distribution information of the M-th needling
simulation is obtained; 4, combining all needling point distribution information of each time of needling simulation; 5, drawing and displaying the needling effect picture. With an assistance from the real-time needling track simulating
system, the needling machine can greatly shorten the trial manufacture time of products in a new type, reduce the dependence on operators and decrease the trail manufacture cost.
