For railroad tracks to cross each other, such a diamond creates a necessary but unfortunate gap in the rails. The train's wheels pass over the gap, causing a brief high-impact event of wheel on rail. This can gradually deform the rail locally, as well as degrade the ballast over time. Crossing diamonds are track segment requiring ongoing maintenance. https://obj-engineer.com/wp-content/uploads/2019/07/wm_shust_mugshot2016.jpgwm_shust_mugshot2016https://obj-engineer.com/wp-content/uploads/2019/07/wire_rope_isolator_trailer1dscn1407.jpgwire_rope_isolator_trailer1DSCN1407The cryomodule to be transported is supported by two nesting truss-like shipping frames (blue members). An array of flexible wire-rope shock and vibration isolators connect the inner frame to the outer frame. The outer frame is then secured to the Class 8 air-suspension flatbed trailer. Careful planning of the route is required for safe transit of this delicate piece of technology.https://obj-engineer.com/wp-content/uploads/2019/07/wire_rope_isolaotr_2_dscn1406.jpgwire_rope_isolaotr_2_DSCN1406Shipping cage and vibration isolators for cryomodule transportation. In 2018-19, transportation trials were unsuccessful in delivery of two early assemblies of cryomodules. Objective Engineers was contacted, and hence assisted two national labs with the identification of best practices for transporting several dozen delicate pieces of a linear particle accelerator from Illinois to California.https://obj-engineer.com/wp-content/uploads/2019/07/ultrasonic_intermodal_lean_tests_dsc_0638.jpgultrasonic_intermodal_lean_tests_DSC_0638In 2013, Objective Engineers was tasked to investigate leaning intermodal railcars. We developed an ultrasonic measuring array (shown attached to this pickup truck) which measured the leaning angles of trailers and containers as trains entered a railroad yard.https://obj-engineer.com/wp-content/uploads/2019/07/turnout_derailment_investigations_2017_dscn1050.jpgturnout_derailment_investigations_2017_DSCN1050In 2017, Objective Engineers was called upon to investigate a derailment at this yard switch. Rail profiles and track geometry measurements supported subsequent computer modeling of the most-likely train actions.https://obj-engineer.com/wp-content/uploads/2019/07/trkgeom.jpgtrkgeomhttps://obj-engineer.com/wp-content/uploads/2019/07/topeka_wheel_rail_postiion_2018_img_20180927_135422670.jpgTopeka_wheel_rail_postiion_2018_IMG_20180927_135422670A detailed view of a railcar wheel negotiating a switch frog. https://obj-engineer.com/wp-content/uploads/2019/07/topeka_wheel_into_frog_2018_img_20180927_135401069_hdr.jpgtopeka_wheel_into_frog_2018_IMG_20180927_135401069_HDRAs a railcar negotiates a switch or turnout in the track, it encounters a special piece of trackwork call the frog. This is where the new direction of travel diverges from the original route, and the wheel must successfully travel through a flangeway gap. This wheel is rolling toward the viewer and is about to reach the throat of the frog. Notice that the contact point between the wheel and rail is at the right edge of the tread.https://obj-engineer.com/wp-content/uploads/2019/07/topeka_wheel_contact_frog_hollow_img_20180927_135422670.jpgtopeka_wheel_contact_frog_hollow_IMG_20180927_1354226702020-07-29T23:22:58+00:00weekly0.6https://obj-engineer.com/reference-library/2020-07-10T19:47:17+00:00weekly0.6https://obj-engineer.com/instrumentation-for-rent/edaq/2020-06-15T20:43:21+00:00weekly0.6https://obj-engineer.com/instrumentation-for-rent/2020-06-15T20:19:26+00:00weekly0.6https://obj-engineer.com/about/resume/2020-06-15T19:59:14+00:00weekly0.6https://obj-engineer.com/about/contact/2020-06-15T19:57:51+00:00weekly0.6https://obj-engineer.com/about/2020-06-15T19:47:25+00:00weekly0.6https://obj-engineer.com/links/2019-08-07T22:11:06+00:00weekly0.6https://obj-engineer.com/links/professional-colleagues/2019-08-07T00:23:36+00:00weekly0.6https://obj-engineer.com/links/interesting-webpages/2019-08-07T00:16:18+00:00weekly0.6https://obj-engineer.com/links/professional-development/2019-08-07T00:15:16+00:00weekly0.6https://obj-engineer.com/links/transportation/2019-08-07T00:14:13+00:00weekly0.6https://obj-engineer.com/about/past-clients/2019-07-04T19:23:15+00:00weekly0.6https://obj-engineer.com/2019/04/19/the-journey-begins-2/2019-04-19T13:27:54+00:00monthlyhttps://obj-engineer.comdaily1.02020-07-29T23:22:58+00:00
