Abstract:

دراین مقاله پس ازبیان نمودن دلایل بوجود آمدن تبدیل ویولت وافزایش استفاده ازآن جهت مقاصد عیب یابی رابطه ریاضی تبدیل ویولت پیوسته ارایه شدها ست پس ازآن به بررسی دوفاکتور تعدادلحظات مساوی باصفروقابلیت تشخیصی که یک تابع ویولت میتواندداشته باشد پرداخته ایم ونقش این دوعامل را درانتخاب تابع ویولت مادرباتوجه بهماهیت سیگنال اصلی ازلحاظ گذرا ویاپایدار بودن بررسی نموده ایم درادامه توابع ویولتی را که درزمینه عیب یابی ماشین آلات مکانیکی کاربرد شایع تری دارند را باذکرمنابع ومثالها مورد بررسی قرارداده ایم باتوجه به نتایج تحقیق مشخص شده است که تابع ویولت دابچیز تقریبا شایع ترین کاربرد را دارد
