REXS V1.6

The REXS model is contained in a JSON object called "model," which includes a row of name-value pairs. In addition to the metadata ("version," "applicationId," "applicationVersion," "date," "applicationLanguage"), the "model" object contains the "relations" and "components" arrays, as well as a "load_spectrum" object if applicable.

Example model REXS file | JSON syntax

{"model": { "version": "1.4",  "applicationId":"FVA-Workbench", "applicationVersion":"7.0.0", "date":"2021-11-03T11:35:17+01:00", "applicationLanguage":"en",
				"relations": [...],
				"components": [...],
				"load_spectrum": {...} (optional)
	   } }

The "components" array contains a list of JSON objects. Each of these objects includes the name-value pairs "id" (ID of the component), "name" (component name), "type" (component type), as well as the "attributes" array.

Example components | JSON syntax

"components":[
	{"id":4, "type"="cylindrical_gear", "name":"Pinion",
		"attributes": [
			{"id": "attr1", "boolean": false},
			{"id": "attr2", "unit": "none", "floating_point": 0.1},
                        ...
		]
	},
	{"id":6, "type"="cylindrical_gear", "name":"Wheel",
		"attributes": [
			...
		]
	}
]

The "relations" array contains a list of JSON objects. Each of these objects includes the name-value pairs "id" (ID of the relation), "type" (type of relation), "order" (for relevant relation types), and the "refs" array. The "refs" array contains a list of objects with the name-value pairs "role" (role of the component in the relation), "id" (ID of the component in the relation), "hint" (optional addition for improved clarity).

Example REXS file relations | JSON syntax

"relations": [ 
	{"id":15, "type":"ordered_assembly", "order":1,
	"refs": [
		{"id":8, "role":"assembly", "hint":"bearing"},
		{"id":16, "role":"part", "hint":"bearing_row"}
		]
	},
	{"id":23, "type":"stage",
	"refs": [
		{"id":3, "role":"stage", "hint":"cylindrical_stage"},
		{"id":7, "role":"gear_1", "hint":"cylindrical_gear"},
		{"id":9, "role":"gear_2", "hint":"cylindrical_gear"}
		]
	},
]

The "load_spectrum" object includes the name-value pairs "id" (ID of the load spectrum), "accumulation" (sub-model for accumulated values of the spectrum), and the "load_cases" array. The "accumulation" object contains a "components" array. The "load_cases" array contains a list of JSON objects, each of which includes both an "id" and a "components" array.

Example load spectrum | JSON syntax

"load_spectrum": {
		"id": 1,
		"load_cases": [
			{ 
				"id": 1,
				"components": [
					{ "id": 1, "attributes": [...]},
					{ ... },
					...
				]
			},
			{
				"id": 2,
				"components": [
					{ "id": 2, "attributes": [...]},
					{ ... },
					...
				]
			},
			...
		]
		"accumulation": {
			"components": [
				{ "id": 2, "attributes": [...]},
				{ ... },
				...
			]
		}		
}
