Introduction With the increasing demand for garbage disposal, complex operating environments and frequent use require truck manipulators to have better performance. Methods This study designs a multifunctional robotic arm trucks, which has three basic degrees of freedom, is driven by hydraulic cylinders, claw type end effector. Through theory relative motion linkage mechanisms, mechanics, including forward inverse kinematics problems, are analyzed, methods calculating joint driving forces, rod angular velocities, other parameters determined. In structural optimization design, reducing weight taken as objective function. At same time, considering performance indicators such stiffness strength, material selection, manufacturing errors, cost constraints set constraints, carried out using finite element analysis topology optimization. Results After optimization, overall mass function reached 64.39 kg after 11th decrease about 14.28% compared initial 75.12 kg. terms processing factors, optimized accuracy been improved ±0.15 mm, cutting speed some materials increased 20%, mold production cycle shortened 30%. Discussion The results show that stress distribution structure changed but still meets requirements strength stiffness. design effectively improves arm, reduces costs, beneficial more stable efficient operations in collection transportation.
