Passengers cars and light trucks with up to three axles can be investigated. Beside vertical excitation logitudinal excitations are possibel as well. A 900t-foundation seperates the oscillations from the bulding. Applications are: Endurance tests of vehicles or components, optimization of damper or spring characteristics, comfort.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"987\" height=\"1019\" src=\"https:\/\/www.hsu-hh.de\/ft\/wp-content\/uploads\/sites\/718\/2021\/03\/Excitation_test_rig.jpg\" data-credit=\"Automotive Engineering\" alt=\"Excitation test rig\" class=\"wp-image-940\" srcset=\"https:\/\/www.hsu-hh.de\/ft\/wp-content\/uploads\/sites\/718\/2021\/03\/Excitation_test_rig.jpg 987w, https:\/\/www.hsu-hh.de\/ft\/wp-content\/uploads\/sites\/718\/2021\/03\/Excitation_test_rig-291x300.jpg 291w, https:\/\/www.hsu-hh.de\/ft\/wp-content\/uploads\/sites\/718\/2021\/03\/Excitation_test_rig-768x793.jpg 768w\" sizes=\"auto, (max-width: 987px) 100vw, 987px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h3 class=\"wp-block-heading\">Test Rig Data<\/h3>\n\n\n\n<h4 class=\"wp-block-heading\">Complete Vehicle<\/h4>\n\n\n\n<ul class=\"wp-block-list\"><li>Wheel loads: 100 kN \/ wheel; up to six wheels<\/li><li>Stroke: 400 mm<\/li><li>Frequency: up to 20 Hz<\/li><li>Foundation: fixed 900 t or 300 t (sprung) elastically joined with 600 t (unsprung)<\/li><\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Components<\/h4>\n\n\n\n<ul class=\"wp-block-list\"><li>Loads: 10 &#8211; 100 kN<\/li><li>Stroke: 100 &#8211; 400 mm<\/li><li>Frequency:  20 &#8211; 40 Hz<\/li><li>Foundation: fixed 900 t or 300 t (sprung) elastically joined with 600 t (unsprung); more smaller foundations<\/li><\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Inidividual<\/h4>\n\n\n\n<p>The different servohydraulic cylinders can be arbitrarily combined by suitable mechanical elements.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"498\" height=\"776\" src=\"https:\/\/www.hsu-hh.de\/ft\/wp-content\/uploads\/sites\/718\/2021\/02\/Gabelstapler1-1.jpg\" data-credit=\"Ph.D. thesis N.
