As one of the means of transport logistics truck mainly, has an irreplaceable role in thetransport industry. But because the forklift industry in China started late, production anddetection of forklift depend on experience, so in the design of forklift process ineviTably thereare some irregularities. In the automotive industry, computer aided design and computer aidedengineering has made great achievements, the practical application of this technology alsoneed forklift industry.A balanced4ton diesel forklift factory production of the WL truck are studied, theforklift parts as the main object of study, first determine the internal combustion forklift trucksuse the fork, door frame, door frame of the external shape, the door frame components of thematerial used, then in the rated load conditions, the three part isolated stress analysis,movement analysis of portal frame system, calculation of lifting the actual height ofmaximum when the door frame system and upright tilt the force size, determine the forkliftlifting of the maximum stress state.Then the use of Catia digital modeling,3D modelling Fig. fork and inside and outsidethe door frame, then the model is imported into Hyperwork software, import materialproperties, applied stress state is close to the actual results, and analyze whether the materialperformance requirements in practical condition. The model is imported into Workbenchsoftware, make the mode analysis of the view can meet the requirements, the vibration in thenormal running state. Then, according to industry standards to check the4T forklift forklift isqualified.And then discuss the4T balance forklift gantry are in conformity with the requirements ofits use, is to calculate the gantry lifting height is consistent with, due to the reduction of rollercenter distance can lift the appropriate increase, but will increase the stress node by. So, in thematerial door frame with force strength of the need to adjust the roller center distance sizemake it appropriate to improve the lifting height. EsTablish the optimization equation in thispremise, taking into account the actual assembly process, select the appropriate precision, findout the most suiTab. roller center distance, improve the gantry lifting height.
