Production technology improvement and topological optimization are performed for the tilting cylinder block of the forklift mast to complete the design research and target optimization with the major structural dimensions as variables, maximum equivalent stress value as constraint and minimum weight as the objective.The value rounding is made based on the production practices to have the weight of component reduced by 1 6.4%,and maximum equivalence stress reducing by 7.5%.The test shows that the optimized part is qualified,so it is produced in batch by now.
