Abstract

Željom za poboljšanjem udobnosti pacijenta i medicinskog osoblja u medicinskom vozilu određene su performanse medicinskog vozila s aspekta komfora putnika. Mjerenjem vertikalnih, uzdužnih i poprečnih ubrzanja određene su karakteristike udobnosti medicinskog vozila. Dodatnim preliminarnim ispitivanjima na vozilima s drugačijim opružno-prigušnim elementima izmjereni su rezultati za usporedbu s medicinskim vozilom. Za provedbu ispitivanja korištena je dostupna mjerna oprema koja je bilježila ubrzanja, položaj i podatke o radu vozila za vrijeme vožnje. Analizom podataka došlo se do zaključka da vertikalna ubrzanja stvaraju najveću neudobnost vožnje, a tome najviše doprinosi kvaliteta opružno-prigušnih elemenata ovjesa. Može se zaključiti da medicinska vozila sa standardnim stražnjim ovjesom koji koristi lisnate opruge imaju relativno nisku razinu udobnosti vožnje.

Abstract (english)

With the aim of improving the comfort of both patients and medical personnel in a medical vehicle, the vehicle's performance was assessed from the perspective of passenger comfort. By measuring vertical, longitudinal, and transverse accelerations, the comfort characteristics of the medical vehicle were determined. Additional preliminary tests on vehicles with different suspension and damping elements provided results for comparison with the medical vehicle. The available measuring equipment was used to record accelerations, position, and vehicle operation data during driving. Data analysis led to the conclusion that vertical accelerations cause the greatest discomfort during travel, primarily due to the quality of the suspension’s spring-damping elements. It can be concluded that medical vehicles with a standard rear suspension using leaf springs have a relatively low level of ride comfort.
