The output of this test is the FRF = output (f) \/ input (f). The results are independant of the input.<\/p>\n<p>2) Sine-sweep test. This test enforces a base motion having a pre-determined amplitude vs. frequency curve and a sweep rate. The output is the response at selected points vs. frequency. The output varies with varying the sweep rate.<\/p>\n<p>3) Resonance Search (RS) test. This is similar to sine-sweep test, but the base motion amplitude is low level and constant vs. frequency. The output is similar to the Sine-sweep test, and do vary with the sweep rate.<\/p>\n<p>4) Random Vibration Test. The input excitation is applied in the form of Power Spectral Density (PSD), and so is the output, at any point of choice<\/p>\n<p>5) Shock test. The input excitation is specified in terms of the Shock Response Spectrum (SRS). The output should be the spectrum or time history at any specified point.<\/p>\n<p>&nbsp;<\/p>\n<p>Could you please teach me how to simulate these different tests on Ansys?<\/p>\n<p>&nbsp;<\/p>\n<p>Thanks and regards<\/p>\n","protected":false},"template":"","class_list":["post-241597","topic","type-topic","status-closed","hentry","topic-tag-frf-1","topic-tag-harmonic-response","topic-tag-random-vibration"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["92209","58821"],"_bbp_author_ip":["96.7.74.173"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["3443"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_notification_enabled":["452454","452454","452454"],"_bbp_topic_id":["241597"],"_bbp_forum_id":["27791"],"_bbp_engagement":["58821","92209"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["242139"],"_bbp_last_active_id":["242139"],"_bbp_last_active_time":["2022-11-27 07:37:28"]},"test":"ahmed-desokiegsa-gov-eg"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/241597","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/241597\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=241597"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
