چکیده

ریزالور حسگری است که برای تعیین موقعیت گردان یا خطی مورد استفاده قرار می‌گیرد. طراحی بهینه این حسگر، نیازمند یک مدل دقیق و درعین‌حال سریع است. چنین مدلی برای ریزالور خطی، باید قابلیت در نظر گرفتن اثر انتهایی را هم داشته باشد. لذا، در این مقاله یک مدل تحلیلی بر اساس روش زیرناحیه برای ریزالور خطی ارائه می‌شود. این مدل نه‌تنها اثر انتهایی طولی بخش متحرک و ساکن را به خوبی در نظر می‌گیرد؛ بلکه اثر دندانه و شیاردار بودن این دو بخش را نیز مورد توجه قرار می‌دهد. نتایج مدل ارائه‌شده، با نتایج روش اجزای محدود و نتایج آزمایش عملی روی نمونه ساخته‌شده حسگر، مورد ارزیابی و تایید قرار می‌گیرد.
