The Optimized Analysis of Recirculating-Ball Hydraulic Power Steering Gear Based on Orthogonal Experiment

To optimized the structure parameters of steering gear assembled in low speed truck,an orthogonal experiment is designed within rang of variation of the structure parameters,under the guide of vehicle handing and stability comprehensive evaluation indexes.One optimum parameter group is obtained by analyzing the influence of structure parameters on evaluation indexes based on the simulation of the established and verified model of the truck steering system.The optimum parameters group is demonstrated can be benefit to the vehicle handing and stability through contrasting the original structure parameters,and achieving the objective of power steering gear structure parameters optimized analysis.
