For details, see the section correspondingto the subject model.Example of equation for LM Guide model HSRThe equivalent load when a radial load (PR) and alateral load (PT) are applied simultaneously isobtained using the following equation.PE(equivalent load)=PR+PTPR: Radial loadPT: Lateral loadPTFig.10 Equivalent of Load of the LM GuidePLMAMBMCPRMomentin the pitchingdirectionMomentin the yawingdirectionMomentin the rollingdirectionPTIndustrial TechnologiesA1-70
