Accurate　acquisition　of　steering　load　is　one　of　the　foundations　for　high-performance　researching　of　all-terrain　heavy　vehicles　steering　systems　because　of　complex　load　conditions.　In　particular,　online　real-time　acquisition　of　steering　load　of　each　wheel　is　favorable　for　high-performance　control　of　the　complete　vehicle.　This　paper　proposes　a　new　online　real-time　test　method　for　dual　side　wheel　steering　load　based　on　steering　system　mathematical　model　and　tie　rod　force　characteristics.　It＇s　only　needed　to　introduce　the　tie　rod　force　in　real　time　to　obtain　the　dual　side　steering　load.　Meanwhile,　the　proposed　method　based　on　LabVIEW　with　the　function　of　visualized　steering　load　test　and　analysis　is　effectively　verified　by　the　dual　wheel　steering　load　test　bench.　The　method　is　easy　to　implement　and　able　to　provide　accurate　load　data　in　actual　heavy　vehicle,　which　is　helpful　for　the　optimization　design　of　the　system　for　high-performance　electro-hydraulic　control　steering　system.　©　2019　IEEE.
