4D printing structure for improving load deformation performance and design method thereof

The invention relates to 4D printing, in particular to a 4D printing structure for improving load deformation performance and a design method thereof The 4D printing structure is at least provided with two sets of deformation structures which are connected in parallel, and the deformation structures have the same tail end deformation condition under different temperature states. The method comprises the following steps of 1, designing a general shape and a fiber arrangement range after parallel connection of the deformation structures to obtain an integral structure; 2, respectively designing each group of deformation structures in the overall structure, designing and analyzing the tail end deformation condition of each group of deformation structures in an alternate driving state in combination with a pre-programming model, and fitting a deformation track of a tail end; 3, optimizing the driving time sequence of each group of deformation structures, and adjusting driving control parameters to realize that ea
